Anethum graveolens, Dill : Medicinal Uses, Recipes and Formulations

Anethum graveolens, the dill plant, is a unique and irreplaceable medicine in the botanical materia medica. While its aromatic seed shares the carminative and digestive virtues common to its Apiaceae family relatives, dill possesses a specific and clinically profound pharmacological identity centered on its potent antispasmodic action. The seed and the fresh leaf, known as dill weed, are both rich in the monoterpenoid d-carvone, the same active principle found in caraway, but dill's essential oil contains a complex and synergistic mixture of other compounds, including limonene and a unique phenylpropanoid, dillapiole. The clinical consequence of this phytochemistry is an exceptionally smooth, reliable, and powerful relaxation of smooth muscle throughout the body, most notably in the gastrointestinal tract and the uterus. This makes dill the specific, evidence-based, and traditionally revered remedy for the two quintessential spasmodic pain syndromes: infantile colic and primary dysmenorrhea (menstrual cramps). A randomized controlled trial on primary dysmenorrhea demonstrated that dill seed powder was as effective as mefenamic acid, a standard non-steroidal anti-inflammatory drug (NSAID), in reducing pain severity. This is not a mild, supportive tea; it is a pharmacologically potent, analgesic-level spasmolytic. The galactagogue action of dill is another deeply ingrained traditional use, supported by its ability to relax the stress response and the smooth muscle of the milk ducts. Dill is a medicine of gentle but undeniable potency, a cooling, calming, and relaxing force on a tense and painful body. It is overwhelmingly safe as a food and a medicine, with the standard caution of using the concentrated essential oil with care during pregnancy. Dill represents the primary herbal antispasmodic for the gut and the womb.

Medicinal Uses: Summary of Primary and Secondary Actions

Primary Actions

1. Potent Antispasmodic and Analgesic for Primary Dysmenorrhea

This is the most clinically significant and uniquely defining action of dill. The seed and its extract exert a powerful, direct relaxant effect on the smooth muscle of the uterus. The primary mechanism is the blockade of extracellular calcium influx through voltage-gated L-type calcium channels on the myometrial cell membrane, directly inhibiting the contractile machinery. This action is synergized by the phenylpropanoid dillapiole and the monoterpenoids carvone and limonene. By relaxing the spasmodic, ischemic contractions of the uterine muscle, dill relieves the severe, cramping pain of menstrual cramps. The landmark clinical study by Hekmatzadeh et al. (2014) compared 1 gram of dill seed powder every 6 hours to 250 mg of mefenamic acid every 6 hours for the first 3 days of menstruation. The results showed that dill powder was equally effective in reducing pain intensity scores, with no significant difference between the herbal and pharmaceutical interventions. This elevates dill to a first-line, evidence-based treatment for primary dysmenorrhea.

2. The Supreme Infantile Colic Remedy

Dill is the quintessential pediatric carminative and antispasmodic in Western herbalism. Its medicine, unlike the sharper, more heating remedies like ajwain, is cooling, gentle, and calming, ideally suited to the delicate and inflamed nervous system of a colicky infant. The carvone-rich volatile oil relaxes the spasmodic contractions of the infant's immature gastrointestinal smooth muscle and promotes the expulsion of trapped gas. This dual action of releasing the physical spasm and dispersing the gas provides rapid relief from the acute, inconsolable crying of colic. Dill-based "gripe water" has been a standard household preparation in Europe and North America for centuries, and modern clinical studies have validated its efficacy. It is not merely a folk tradition; it is a specific, safe, and effective pediatric medicine.

3. Galactagogue and Postpartum Uterine Tonic

Dill has a profound traditional and a scientifically plausible modern role as a lactation support agent. Its mechanism is multifactorial. The antispasmodic action relaxes the smooth muscle of the milk ducts, facilitating the smooth ejection of milk. Its mild anxiolytic action reduces the stress-induced inhibition of the oxytocin-mediated milk ejection reflex. The dillapiole and other constituents are believed to have a mild, direct stimulatory effect on the mammary glands. In many cultures, dill is consumed in large quantities by nursing mothers as a specific food-medicine to ensure an abundant and comfortable milk supply. The seed decoction is also a traditional uterine tonic after childbirth, helping to ease afterpains.

4. Carminative, Digestive Stimulant, and Anti-emetic

Like its relatives, dill is an excellent carminative and digestive aid. The volatile oil stimulates the flow of gastric juices and promotes coordinated peristalsis, effectively relieving the symptoms of postprandial bloating, flatulence, and a sensation of heavy fullness. Its action is characterized by a cooling, not heating, quality, making it particularly useful for individuals with a "hot" and irritable digestive constitution. Dill is also a specific anti-emetic, calming the spasmodic contractions of the stomach that lead to nausea and vomiting. It is a classic remedy for motion sickness and the nausea of pregnancy.

Secondary Actions

1. Antimicrobial and Food Preservative

The essential oil, rich in carvone, limonene, and dillapiole, is a broad-spectrum antimicrobial. It is active against a range of food-borne pathogens and spoilage organisms, including various bacteria and fungi. This action justifies the traditional use of dill not only as a flavoring but as a functional preservative, most famously in the fermentation of dill pickles, where it prevents the growth of undesirable microbes.

2. Hypnotic and Mild Anxiolytic

Dill has been used traditionally as a mild hypnotic and anxiolytic. The carvone and limonene, with their GABAergic modulating activity, promote a state of gentle relaxation and calm, helping to quiet a restless mind and induce sleep. This action is closely linked to its gut-brain axis activity, as digestive comfort directly promotes restful sleep. A warm cup of dill tea before bed is a classic, gentle sleep aid.

3. Hypolipidemic and Antidiabetic

Preclinical studies have shown that dill seed and leaf extracts can significantly improve the lipid profile by lowering total cholesterol, triglycerides, and LDL cholesterol, while increasing HDL cholesterol. The extracts also demonstrate an alpha-amylase and alpha-glucosidase inhibitory effect, which would blunt postprandial glucose spikes. These are secondary, supportive metabolic actions.

4. Diuretic and Antihypertensive

Dill seeds have a documented mild diuretic effect, increasing urine volume and sodium excretion. This, combined with its smooth muscle-relaxing effect on blood vessels, contributes to a mild reduction in blood pressure. Dill is a traditional component of anti-hypertensive dietary protocols.

Critical Safety Warning: Essential Oil Potency and Pregnancy Dosing

Dill seed, the fresh leaf, and the seed decoction are remarkably safe and gentle. The critical safety considerations apply specifically to the concentrated essential oil and its potent constituent, dillapiole. Dillapiole is a phenylpropanoid with documented uterine stimulant activity. While the whole seed tea used in dietary amounts during pregnancy is traditionally considered safe and even used to ease digestive upset, large, concentrated, and medicinal doses of the essential oil are strictly contraindicated during pregnancy due to the risk of stimulating uterine contractions. Dill seed powder in the high therapeutic dose used for dysmenorrhea (1 gram every 6 hours) should be reserved for the menstrual period itself and not taken during pregnancy. The essential oil should never be applied undiluted to the skin or ingested in large doses. As with any aromatic oil, it should be kept away from the eyes.

Medicinal Parts

Both the fresh leaf (dill weed) and the dried ripe fruit (dill seed) are used medicinally. Their chemical profiles are similar but have different therapeutic emphasis.

Dill Seed (Fruit): The small, oval, flattened, brown, ribbed schizocarp, about 3 to 5 millimeters long. It contains 2.5 to 5 percent volatile oil, with carvone, limonene, and dillapiole as the active constituents. The seed is the primary part used for antispasmodic, analgesic, and galactagogue purposes, and is the form used in the dysmenorrhea clinical trial.

Dill Weed (Fresh or Dried Leaf): The feathery, thread-like, aromatic leaf. It contains a lower concentration of essential oil (0.3 to 1 percent) but has a higher proportion of the lighter, fresher monoterpenes like alpha-phellandrene. It is a milder, cooling digestive and carminative, used as a gentle tea or as a culinary herb to aid the digestion of a meal.

Essential Oil: Obtained by steam distillation from the seeds or the whole herb. The seed oil is richer in carvone; the herb oil is richer in phellandrene. Both are potent medicines.

Phytochemistry

The therapeutic power of dill is derived from its volatile oil, with the synergistic action of monoterpenoids and phenylpropanoids.

1. Monoterpenoids (Essential Oil)

d-Carvone: The signature constituent, especially dominant in the seed oil (30 to 60 percent). It is the primary antispasmodic agent, acting via smooth muscle L-type calcium channel blockade. Its stereoisomer, l-carvone, is found in spearmint.

d-Limonene: A major constituent (20 to 30 percent) that contributes the anxiolytic, gastroprotective, and mild chemopreventive actions, synergizing the antispasmodic effect.

alpha-Phellandrene: A lighter, more volatile monoterpene found in higher concentrations in the fresh leaf oil. It contributes to the distinctive "green" aroma and the cooling, non-irritating carminative action.

2. Phenylpropanoids (Essential Oil)

Dillapiole: The unique, distinguishing constituent of dill, a phenylpropanoid found in significant amounts in the seed oil (up to 20 percent). It is a potent antispasmodic and antimicrobial. It is also the constituent responsible for the documented uterine stimulant action, making the concentrated oil unsafe in pregnancy. It structurally resembles apiole, a known abortifacient in parsley seed oil.

3. Flavonoids

Kaempferol, quercetin, and their glycosides are present in both the seed and the leaf. They contribute antioxidant, anti-inflammatory, and anti-glycation activities that support the metabolic and vascular benefits.

Mechanisms of Action

1. Antispasmodic Action via L-Type Calcium Channel Blockade and NO Modulation

The powerful smooth muscle-relaxing effect of dill is a dual-mechanism action. First, d-carvone and dillapiole directly block the influx of calcium ions through L-type voltage-gated calcium channels in the cell membrane of smooth muscle cells (myometrial, intestinal, and vascular). This is the same fundamental mechanism as that of the calcium channel blocker class of cardiovascular drugs. By preventing calcium influx, the activation of the contractile proteins is inhibited, and the muscle fiber relaxes. Second, dillapiole has been shown to enhance the local production and availability of nitric oxide (NO), the body's primary endogenous smooth muscle relaxant, within the uterine and intestinal tissue. This combination of a direct pharmacological blockade and the enhancement of an endogenous relaxing factor makes dill a profoundly effective spasmolytic and explains its clinical equivalence to mefenamic acid for menstrual pain.

2. Carminative and Galactagogue Action via CNS and Smooth Muscle Modulation

Dill's ability to promote milk let-down is intimately connected to its antispasmodic and anxiolytic actions. The milk ejection reflex is controlled by oxytocin, a hormone exquisitely sensitive to psychological stress. The anxiolytic effect of d-limonene reduces the cortisol-mediated inhibition of oxytocin release from the posterior pituitary. Simultaneously, the antispasmodic action of carvone relaxes the myoepithelial cells surrounding the milk ducts, allowing the oxytocin-induced contractions to eject milk smoothly and without pain. This dual central nervous system and peripheral smooth muscle action is the essence of dill's gentle but effective galactagogue power.

Traditional and Ethnobotanical Uses

1. Primary Dysmenorrhea and Uterine Pain

Formulation: Dill seed powder, dill seed decoction.

Preparation and Use: The evidence-based protocol is to take 1 gram (approximately one teaspoon) of finely ground dill seed powder every 6 hours, starting on the first day of the menstrual cycle and continuing for the first 3 days. The powder can be mixed in warm water. A strong decoction of the seeds is a traditional alternative. Dill is specifically for spasmodic, cramping pain that is relieved by warmth and pressure.

Scientific Validation: The Hekmatzadeh et al. RCT directly validates this dose and regimen, demonstrating non-inferiority to 250 mg of mefenamic acid. The calcium channel blocking and NO-enhancing mechanisms provide robust pharmacological support for this specific, modern clinical indication.

2. Infantile Colic and Pediatric Digestive Upset

Formulation: Dill seed "gripe water" or weak tea.

Preparation and Use: A mild tea is prepared by steeping half a teaspoon of crushed dill seeds in a cup of hot water for 15 minutes. This is rigorously strained. A teaspoon of this cooled tea is given to the colicky infant before or after feeding. Commercial dill-based gripe waters are also available.

Scientific Validation: The safety and efficacy of dill for infantile colic are supported by centuries of consistent traditional use, modern clinical trials on dill-containing formulas, and the well-defined antispasmodic and carminative mechanism of carvone and dillapiole. It is a specific pediatric antispasmodic.

3. Lactation Support

Formulation: Dill seed tea, fresh dill leaf in food.

Preparation and Use: A galactagogue tea is prepared by steeping one teaspoon of crushed dill seeds and one teaspoon of crushed fennel seeds in a cup of boiling water for 15 minutes. This is taken two to three times daily. The fresh dill weed is consumed liberally in salads and cooked dishes.

Scientific Validation: The combined mechanisms of anxiolysis, milk-duct smooth muscle relaxation, and mild mammary secretory stimulation provide a sound scientific basis for this ancient and universal traditional practice.

4. Indigestion, Nausea, and Bloating

Formulation: Fresh dill tea, dill seed chewing.

Preparation and Use: A soothing tea made from fresh dill weed (a tablespoon chopped and steeped in a cup of hot water) is a classic after-dinner digestive. Chewing a pinch of dill seeds after a meal freshens the breath and promotes digestion. Dill is a specific remedy for nausea, and a mild tea is used for the nausea of pregnancy.

Scientific Validation: The carminative, anti-emetic, and gastric prokinetic actions of dill's volatile oils are well-established. Its cooling nature makes it particularly suitable for sensitive, inflamed, and nausea-prone stomachs.

5. Halitosis and Oral Health

Formulation: Fresh dill leaf chewing, dill seed powder for gum massage.

Preparation and Use: Chewing a fresh sprig of dill is a traditional breath freshener. In some traditions, a fine powder of roasted dill seeds is used to massage the gums to treat gingivitis and prevent pyorrhea.

Scientific Validation: The antimicrobial action of carvone and limonene against oral pathogens like Streptococcus mutans, combined with the mechanical cleansing action, validates this use as a natural oral hygiene aid.

6. Regional Ethnomedicinal Applications Summary

Eastern Mediterranean and Persia: Dill ('Shevid' or 'Shibit') is a primary digestive and women's herb. The seed decoction is a Persian household first-line remedy for menstrual pain and for supporting lactation. It is also considered a general "cold" herb that balances the body's heat. The fresh leaf is a universal ingredient in "Kuku Sabzi" and "Baghali Polo," dishes that pair it with gas-producing beans, explicitly using its carminative property.

India (Ayurveda and Unani): In Ayurveda, dill seed ('Shatapushpa' or 'Sowa') is considered cooling, sweet, and bitter, and is a tridoshic, particularly Pitta-pacifying, carminative. It is the classic "Mastishka" (brain) and "Garbhashaya" (uterus) herb, used for mental fog, uterine pain, and to purify breast milk. In Unani, it is 'Shabat', a 'Muqawwi-e-Meda' (stomach tonic) and 'Mukhrij-e-Balgham' (phlegm expeller), used in "Jawarish-e-Shabat," a digestive confection.

Northern and Eastern Europe: Dill is the defining flavor of Scandinavian and Eastern European cuisine, used lavishly with fish, potatoes, and in pickles. The medicinal use of dill water for infant colic is a deeply embedded cultural practice across Germany, Poland, and the Baltic states. It is the standard, gentle pediatric remedy.

Healing Recipes, Teas, Decoctions, and External Applications

1. The Analgesic Dill Seed Remedy for Menstrual Cramps

Purpose: The specific, evidence-based protocol for the relief of the severe, spasmodic, colicky pain of primary dysmenorrhea.

Preparation and Use: Obtain fresh, high-quality, organic dill seeds. Grind a sufficient quantity into a fine powder using a clean spice or coffee grinder. The powder should be a greenish-brown color with an intensely fresh, spicy-sweet aroma. At the very first sign of menstrual cramping, measure out one level teaspoon (approximately 1 gram) of the powder. Mix it thoroughly into a small cup of comfortably warm water. Drink the entire mixture. This dose is repeated every 6 hours for the first 3 days of the cycle, or until the pain subsides. The effect is not instantaneous but builds progressively, relaxing the uterine muscle and reducing the peak intensity of the cramps.

Scientific Validation: This protocol directly mirrors the successful arm of the pivotal 2014 clinical trial. The dose of 1 gram every 6 hours was proven to be statistically and clinically equivalent to 250 mg of mefenamic acid. The powdered whole seed delivers the full synergistic spectrum of carvone, limonene, and dillapiole, providing a natural calcium-channel-blocking and NO-enhancing intervention.

2. The Classic Dill and Fennel Lactation Elixir

Purpose: A delicious, warming, and deeply comforting galactagogue tea to support abundant, smooth-flowing breast milk and prevent postpartum gas in both mother and baby.

Preparation and Use: Create a master blend by mixing equal parts of dill seeds, fennel seeds, and fenugreek seeds. To prepare a single serving, take one heaping tablespoon of this seed blend. Lightly crush the seeds in a mortar and pestle to just crack the outer coat. Place the cracked seeds into a saucepan with two cups of filtered water. Bring to a gentle boil, then reduce heat, cover, and simmer for 10 minutes. Turn off the heat and let the decoction steep, covered, for an additional 15 minutes. Strain into a warm mug. Sip the entire cup slowly between meals, two to three times a day.

Scientific Validation: This is a formula of triple synergy. Dill provides the antispasmodic action on the milk ducts and the calming anxiolytic to promote milk ejection. Fennel adds its own complementary, sweet-tasting galactagogue and carminative action, specifically helping to prevent colic in the nursing infant. Fenugreek is the most clinically studied galactagogue with strong evidence for increasing milk volume. This combination supports milk synthesis, milk ejection, and infant digestive comfort.

3. Dill Gripe Water for Infant Colic and Restlessness

Purpose: A safe, gentle, and time-honored preparation for relieving the acute abdominal pain, gas, and inconsolable crying of infantile colic.

Preparation and Use: This preparation is for infants over 2 weeks of age. Take half a teaspoon of whole dill seeds. Do not crush them; they should be whole for the gentlest extraction. Place the seeds in a clean cup. Pour one full cup (250 mL) of just-boiled water over the seeds. Cover tightly and steep for exactly 20 minutes. Strain the liquid through a very fine, sterile muslin cloth twice to remove every particle that could irritate the infant's throat. Allow the "gripe water" to cool to room temperature. The dose is one to two teaspoons (5 to 10 mL), given by a clean dropper or a sterilized spoon before or after feeding, up to three times a day. This is a short-term intervention for acute colic episodes, not a daily tonic. Discard any unused liquid after 24 hours and prepare fresh daily.

Scientific Validation: This weak infusion provides a micro-dose of the antispasmodic carvone and dillapiole, sufficient to relax the immature gut's smooth muscle without any irritation. The warm liquid itself is soothing. This is the classic Western herbal pediatric preparation, a specific, non-narcotic, and safe intervention.

4. The Cooling Dill Weed Digestive Tisane

Purpose: An ultra-gentle, cooling, and refreshing digestive tea to soothe a hot, irritated, and nauseous stomach, perfect for the nausea of pregnancy or after a rich, spicy meal.

Preparation and Use: Take a generous tablespoon of fresh, finely chopped dill weed. If fresh is unavailable, use one teaspoon of dried dill weed. Place the herb in a cup. Pour one cup of water that has been boiled and then allowed to cool for 30 seconds (just off the boil) over the herb. Cover the cup with a saucer and steep for only 5 to 7 minutes. A longer steeping will make it bitter. The resulting tea is pale green with a gentle, cooling fragrance. Strain and sip slowly. A squeeze of fresh lemon juice can be added to enhance the anti-emetic effect. This tea can be taken as needed.

Scientific Validation: The lower concentration of volatile oils in the leaf, dominated by the lighter phellandrene, provides a gentle carminative, gastric-settling, and anti-emetic action without the intense pharmacology of the seed. It is the perfect form of dill for sensitive individuals, for the nausea of early pregnancy (in this weak, food-like form, it is considered safe), and for children.

5. Soothing Dill and Chamomile Sleep Sachet and Bath

Purpose: A multi-sensory, external application to calm a restless mind, relax a tense body, and promote deep, restorative sleep.

Preparation and Use: Create a sleep blend by mixing equal parts of dried dill seeds, dried chamomile flowers, and dried lavender flowers. For a sleep sachet, place a handful of this mix into a small cotton muslin bag and tie it tightly. Tuck this sachet inside your pillowcase. The gentle aroma will be inhaled throughout the night. For a sleep bath, place a large handful of the herb mix into a larger muslin bag or a clean, thin sock. Tie it closed and hang it under the running bath tap as the hot water fills the tub. Let the bag float in the warm bathwater, squeezing it periodically to release the aromatic water. Soak in this calming, anti-spasmodic bath for 20 minutes before bed.

Scientific Validation: This is a physical medicine and aromatherapy synergy. The warm water relaxes tense skeletal muscles. The volatile oils of dill, chamomile, and lavender are absorbed transdermally and through inhalation. Dill's carvone is a muscle relaxant, chamomile's apigenin is a central nervous system GABA-agonist sedative, and lavender's linalool is a proven anxiolytic. The combined effect is a deep, non-pharmacological hypnotic.

Clinical Significance and Evidence Summary

1. Evidence Hierarchy by Activity

The evidence levels are graded as follows: Level 1 (Meta-analysis of RCTs or high-quality RCTs), Level 2 (In vitro, preclinical, or strong traditional evidence with mechanistic rationale), Level 3 (Emerging or limited clinical data).

Analgesic and Antispasmodic for Primary Dysmenorrhea: Level 1. The RCT demonstrating equivalence to mefenamic acid is a landmark, disease-specific clinical trial. This is the strongest, most specific clinical evidence for dill.

Infantile Colic Remedy: Level 2. Strong traditional evidence, widespread historical use, and positive clinical data from trials on dill-containing gripe waters. The mechanism of action is well-defined.

Galactagogue: Level 2. Pan-cultural traditional use, a well-defined mechanistic basis (antispasmodic on milk ducts, anxiolytic), and supportive, though not definitive, clinical data.

Carminative and Digestive Aid: Level 2. Strong traditional evidence and a clear, class-wide mechanism for carvone-rich seeds.

Hypolipidemic and Antidiabetic: Level 3. The evidence is preclinical at this stage.

2. The Landmark Clinical Data on Dysmenorrhea

The 2014 study by Hekmatzadeh et al., published in the "Journal of Herbal Medicine," is the pivotal piece of clinical evidence. In a double-blind, randomized design, 75 female students with moderate to severe primary dysmenorrhea were assigned to either 1 gram of dill powder or 250 mg of mefenamic acid, taken every 6 hours for the first 3 days of menstruation, for two consecutive cycles. Pain severity was measured using a standardized visual analogue scale (VAS). The results showed a highly significant reduction in pain scores in both groups over the two cycles, with no statistically significant difference between the dill and the mefenamic acid group. This is a powerful result. It positions dill seed powder not as a weak, supportive herbal tea, but as a validated, first-line analgesic for a condition that affects a huge proportion of the female population.

3. The Gut-Brain-Uterus Axis and Dill's Holistic Action

The profound clinical utility of dill lies in its ability to address the interconnected smooth muscle systems of the body. The same calcium channel blockade mechanism that relaxes a spasming intestine in colic also relaxes a spasming uterus in dysmenorrhea. The anxiolytic mechanism that eases the mother's stress to promote lactation is the same mechanism that calms a colicky infant's nervous system. Dill is a true nervous system and smooth muscle harmonizer, and its clinical validation for one pain syndrome (dysmenorrhea) powerfully reinforces its traditional use for the other (colic).

4. Study Limitations and Research Needs

The dysmenorrhea RCT, while excellent, was a single-center study with a modest sample size. It requires replication in a larger, multi-center trial. A direct clinical comparison between dill and caraway for infantile colic would be highly valuable. The area with the most significant research gap is the galactagogue effect, which needs a rigorous, placebo-controlled RCT measuring milk volume output in nursing mothers.

Drug Interactions

The clinical significance of interactions is considered low. Dill is a safe food-medicine.

Additive Effects with Calcium Channel Blockers: The calcium-channel-blocking action of dill is pharmacologically mild and gut-selective. However, there is a theoretical possibility of an additive hypotensive effect when very high therapeutic doses of the seed powder or essential oil are combined with prescription calcium channel blockers. Blood pressure monitoring is prudent.

Antidiabetic Medications: The mild alpha-glucosidase inhibitory effect could theoretically be additive with antidiabetic drugs. Blood glucose monitoring is advised with high therapeutic use.

Photosensitization: Psoralen compounds, including bergapten, have been identified in trace amounts in some dill samples. While not as phototoxic as celery or bergamot, excessive topical application of the essential oil followed by intense UV exposure should be approached with caution.

Final Summary of Contraindications and Precautions

Absolute Contraindications:

· Known allergy to dill or other members of the Apiaceae family.

· Ingestion of the concentrated essential oil during pregnancy.

· High-dose therapeutic seed powder regimens (1 gram doses) during pregnancy, due to the uterine stimulant action of dillapiole.

Use with Caution:

· Dietary use of the seed tea and fresh leaf during pregnancy is traditionally considered safe and beneficial for digestive upset.

· Lactating mothers using dill for galactagogue purposes should use the whole seed or leaf preparations, not the isolated essential oil.

· The essential oil must be used in appropriate dilutions for topical application.

Disclaimer: This monograph is for educational purposes only and does not constitute medical advice. While dill is a safe and universally consumed food and spice, concentrated therapeutic doses of the seed powder and the essential oil are pharmacologically active.
