Aloe vera (Asphodelaceae) Kumari, Korphad

Aloe vera (True Aloe, Medicinal Aloe)

1. Taxonomic insights

Species: Aloe vera (Syn: Aloe barbadensis miller)

Family: Asphodelaceae (formerly placed in Liliaceae)

Genus: Aloe

The Asphodelaceae family consists of many succulent, perennial plants, often storing water and bioactive compounds in their leaves. Several species beyond Aloe vera are sources of medicinal gels or bitter resins.

Related Herbs from the same family:

• Aloe ferox (Cape Aloe): Native to South Africa, it is a primary source of bitter aloes (a powerful purgative). It is commercially important and used in Western herbalism for its strong laxative properties derived from its leaf exudate.

• Kniphofia uvaria (Red Hot Poker): Primarily an ornamental plant native to Africa, some species within the Asphodelaceae family have limited traditional medicinal uses for conditions like coughs.

• Bulbine frutescens (Burn Jelly Plant): A South African succulent with gel-filled leaves used topically, much like Aloe vera, for burns, wounds, and skin conditions, demonstrating the family's prevalence of plants with mucilaginous healing gels.

• Eremurus spp. (Foxtail Lily): While not a major medicinal herb, it represents the ornamental diversity of the family.

2. Common Names:

Scientific Name: Aloe vera | English: Aloe, True Aloe, Medicinal Aloe, Burn Plant | Sanskrit: Ghritakumari, Kumari | Hindi: Ghikanvar, Guarpatha | Tamil: Katralai, Sotru Katrazhai | Telugu: Kalabanda | Kannada: Lolesara | Malayalam: Kattar vazha | Marathi: Korphad | Bengali: Ghritakumari | Gujarati: Kunvar | Arabic: Sabr, صَبْر | Spanish: Sábila | French: Aloès | German: Aloe, Wüstenlilie | Chinese: Lúhuì (芦荟) | Japanese: Aroe (アロエ) |

3. Medicinal Uses:

Wound Healing, Burn Relief, Anti-inflammatory, Antioxidant, Laxative (strong), Moisturizer, Immunomodulatory, Hypoglycemic, Anti-ulcer, Radioprotective.

Medicinal Parts:The leaf of the Aloe vera plant is the sole medicinal part, but it yields two distinct substances with very different properties.

• Leaf Gel (Parenchyma): The clear, mucilaginous gel found in the inner leaf filet. This is used for topical healing and internal soothing.

• Leaf Latex/Exudate (Aloin): The bitter, yellow latex (sap) found just beneath the leaf skin. This is a potent cathartic used for constipation.

4. Phytochemicals specific to the plant and their action.

Polysaccharides (Acemannan, Glucomannan): These long-chain sugars are the primary bioactive compounds in the gel. Their actions include powerful Immunomodulatory effects (stimulating macrophages), Wound Healing (promoting collagen synthesis and moisture retention), and forming a protective barrier on mucous membranes.

Anthraquinone Glycosides (Aloin, Barbaloin, Emodin): These compounds are concentrated in the leaf latex/sap. Their primary action is a strong Laxative (cathartic) effect by stimulating bowel peristalsis and increasing water content in the colon. They also have Antimicrobial properties.

Enzymes (Bradykinase, Carboxypeptidase): Found in the gel, these enzymes are responsible for its significant Anti-inflammatory and analgesic (pain-relieving) effects, particularly when applied topically. Bradykinase helps break down bradykinin, a key peptide involved in inflammation and pain.

Salicylic Acid & Sterols (Lupeol): These compounds contribute to the gel's Anti-inflammatory and Antiseptic properties. Salicylic acid is a well-known analgesic and anti-inflammatory agent.

Vitamins & Minerals (Vitamins A, C, E, B12, Zinc): These antioxidants and co-factors in the gel support its role in tissue repair, Antioxidant defense, and overall skin health.

5. Traditional and Ethnobotanical uses covering the Medicinal uses.

Daha Prashamana (Soothes Burning) & Vrana Ropana (Wound Healing)

Formulation: Fresh leaf gel.

Preparation & Use: The fresh gel is scooped from a split leaf and applied directly to burns (thermal, sunburn), wounds, cuts, and inflammatory skin conditions like eczema and psoriasis. It is left to dry on the skin.

Reasoning: The polysaccharides and enzymes provide a cooling, moisturizing barrier, reduce inflammation, and accelerate tissue regeneration through cell proliferation and collagen synthesis.

Vibandha (Constipation) & Grahani (Irritable Bowel - with caution)

Formulation: Dried latex (known as "Aloes" or "Kumari rasa" in specific preparations).

Preparation & Use: The bitter yellow latex is dried to form a resinous solid. In tiny, controlled doses (as per Ayurvedic formulation), it is used as a potent purgative to clear severe constipation (Vata imbalance). Note: It is rarely used alone in Ayurveda due to its harsh action and is often combined with corrective spices.

Reasoning: The anthraquinones (like aloin) irritate the colon lining, causing strong contractions and fluid secretion, leading to a powerful laxative effect. Prolonged use can be habit-forming and damaging.

Pitta Shamaka (Pacifies Pitta) & Raktashodhaka (Blood Purifier)

Formulation: Fresh gel consumed internally.

Preparation & Use: A small quantity (1-2 tablespoons) of fresh, well-washed gel (to remove all traces of bitter latex) is taken with water or in juices. It is used to cool excess Pitta, manifesting as acid reflux, skin inflammation, or irritability.

Reasoning: Its cooling, moistening, and anti-inflammatory properties help balance the Pitta dosha. Its mild detoxifying effect is attributed to liver support and antioxidant action.

Stri Rogadhikara (Gynecological Disorders)

Formulation: Kumari Asava (a fermented liquid preparation).

Preparation & Use: Aloe vera gel is a key ingredient in this classical Ayurvedic tonic. It is prescribed for menstrual irregularities, as a uterine tonic, and to support female reproductive health.

Reasoning: Aloe vera is considered a "Rasayana" (rejuvenative) for the female reproductive system (Stri Rogadhikara), likely due to its blood-purifying, anti-inflammatory, and hormone-modulating properties.

6. Healing recipes, Teas, Decoctions and Culinary use (if any):

Fresh Aloe Gel for Burns & Sunburn

Purpose: Immediate first-aid relief and healing.

Preparation & Use:

• Cut a thick, mature leaf from the plant. Slit it open lengthwise.

• Scoop out the clear inner gel, avoiding the yellow latex near the skin.

• Apply the gel directly to the affected area. Reapply as needed.

Kumari (Aloe) Digestive Juice

Purpose: To soothe acid reflux (Pitta imbalance) and support digestion.

Preparation & Use:

• Extract 2 tablespoons of pure inner gel from a leaf.

• Rinse it thoroughly to ensure no latex residue remains.

• Blend with 1 cup of cool water, a pinch of cumin powder, and a teaspoon of honey (optional).

• Drink 30 minutes before a meal. Start with small amounts to ensure tolerance.

Aloe Vera and Neem Skin Paste

Purpose: For acne, inflamed skin, or minor infections.

Preparation & Use:

• Mix 1 tablespoon of fresh aloe gel with 1/2 teaspoon of neem powder.

• Add a pinch of turmeric.

• Apply as a face mask, leave on for 15-20 minutes, and rinse with cool water.

7. Disclaimer:

CRITICAL: The internal use of Aloe vera requires extreme caution. The leaf latex/exudate (yellow sap) is a powerful irritant and cathartic. Long-term internal use of latex can lead to electrolyte imbalance, dependency, and potential kidney damage. Never consume the whole leaf or products containing aloin for extended periods. Use only the pure, thoroughly washed inner gel for internal consumption, and even then, in moderation. Topical use of the gel is generally very safe but may cause allergies in rare cases. Pregnant women, nursing mothers, children, and individuals with kidney or intestinal diseases should avoid internal use.

9. Further study: Plants that might interest you due to similar medicinal properties

1. Curcuma longa (Turmeric, Haridra)

• Species: Curcuma longa | Family: Zingiberaceae | Genus: Curcuma

• Similarities: Both are cornerstone herbs for wound healing and anti-inflammatory action. While turmeric is used more internally as a systemic anti-inflammatory, and aloe topically for localized healing, they are often combined in pastes for skin conditions. Both have significant scientific validation for their healing properties.

2. Simmondsia chinensis (Jojoba)

• Species: Simmondsia chinensis | Family: Simmondsiaceae | Genus: Simmondsia

• Similarities: While not a gel, jojoba oil is a liquid wax ester that mimics human sebum. Like aloe gel, it is a premier skin moisturizer and healing agent used in cosmetics and topical therapies for eczema, psoriasis, and wound care, representing a different botanical approach to skin health.

3. Plantago ovata (Isabgol, Psyllium Husk)

• Species: Plantago ovata | Family: Plantaginaceae | Genus: Plantago

• Similarities: Both are used for bowel regulation but in opposite ways. Isabgol is a bulk-forming, gentle laxative due to soluble fiber, while aloe latex is a stimulant cathartic. This highlights the important distinction: Aloe gel soothes membranes, while its latex aggressively stimulates them. Isabgol is the safer choice for chronic constipation.
