4. Phytochemicals specific to the plant and their action.

Ricinoleic Acid: The main component (up to 90%) of castor oil. This unique fatty acid is responsible for the powerful Purgative action. It stimulates the intestines, promoting strong peristalsis and bowel evacuation.

Ricinine (Alkaloid): Present in the seeds and leaves. It is toxic and a primary reason for the plant's toxicity if seeds are ingested raw. It has insecticidal and potential central nervous system effects.

Flavonoids and Phenolic Compounds: Found in the leaves and roots. These contribute to the Antioxidant, Anti-inflammatory, and Analgesic properties, making extracts useful for pain and inflammation.

Tannins: Present in the bark and leaves, providing Astringent properties useful for wound cleansing.

Unsaturated Fatty Acids (besides Ricinoleic): Such as linoleic and oleic acid. These support skin health and have emollient properties.

5. Traditional and Ethnobotanical uses covering the Medicinal uses.

Purgative (for Severe Constipation and Purgation Therapy)

Formulation: Castor oil extracted from seeds.

Preparation & Use: A small dose (1-2 teaspoons for adults) of pure, processed castor oil is taken orally, usually with warm milk or water, to induce a thorough bowel purge. It is a key drug in Ayurvedic Panchakarma (Virechana).

Reasoning: Ricinoleic acid acts on the intestinal walls, stimulating prostaglandin receptors and causing strong contractions and fluid secretion, leading to defecation.

Anti-inflammatory & Analgesic (for Joint Pain and Arthritis)

Formulation: Poultice of leaves or oil application.

Preparation & Use: Warm castor oil is massaged onto inflamed and painful joints. Alternatively, a poultice made from warmed leaves is bandaged over the affected area (e.g., for rheumatoid arthritis, gout, or lower back pain).

Reasoning: The anti-inflammatory compounds in the oil and leaves penetrate the skin, reducing inflammation and providing pain relief.

Galactagogue (Promotes Lactation)

Formulation: Leaf poultice or mild oil consumption.

Preparation & Use: A poultice of the leaves is applied to the breasts to increase milk flow. In some traditions, a mild dose of a specific medicated castor oil preparation is consumed post-delivery for the same purpose under guidance.

Reasoning: The topical application is believed to stimulate milk flow, while the internal use (under strict supervision) may work by supporting overall purification and health.

Wound Healing and Skin Health

Formulation: Castor oil or leaf paste.

Preparation & Use: Castor oil is applied directly to chronic ulcers, boils, and burns to promote healing. A paste of the seeds (used with extreme caution due to toxicity) was traditionally applied to skin diseases like ringworm.

Reasoning: The oil is emollient and may enhance the penetration of other medicinals. Its antimicrobial and anti-inflammatory properties aid in cleansing and healing wounds.

6. Culinary uses- Decoction, teas, juices and Healing recipes.

WARNING: The seeds (beans) of Ricinus communis are highly toxic due to the presence of the poison ricin and should never be ingested raw. Only the professionally processed and detoxified oil is used for medicinal and external purposes.

Traditional Castor Oil Purge

Purpose: For deep cleansing (Virechana) in Panchakarma or for severe constipation.

Preparation & Use:

• This is a specialized procedure and MUST be done under the supervision of an Ayurvedic practitioner.

• Typically, 1-4 teaspoons of medicated castor oil is consumed with warm milk or ginger tea early in the morning on an empty stomach.

Castor Oil Pack for Pain Relief

Purpose: To reduce inflammation in joints and muscles.

Preparation & Use:

• Soak a flannel cloth in pure, cold-pressed castor oil.

• Place it on the painful area (e.g., knee, abdomen).

• Cover with a plastic sheet and place a hot water bottle on top.

• Leave it for 30-60 minutes. This can be done several times a week.

7. Disclaimer:RICINUS COMMUNIS SEEDS ARE EXTREMELY POISONOUS. INGESTING JUST A FEW SEEDS CAN BE FATAL. Only the professionally processed oil should be used, and that too with caution and professional guidance. Castor oil is a powerful purgative and can cause dehydration, cramping, and electrolyte imbalance. It should not be used by pregnant women, as it can induce labor, or by individuals with intestinal obstructions, appendicitis, or inflammatory bowel disease. Always consult a qualified healthcare provider before using castor oil therapeutically. This information is for educational purposes only.

9. Further study:1. Croton tiglium (Jamalgota): From the same Euphorbiaceae family. It is another drastic purgative, used in minute doses in Ayurveda. This highlights a shared phytochemical strategy within the family for purgative action, though the specific compounds differ (the purgative principle in Croton is croton oil).2. Aloe vera (Kumari): While from the Asphodelaceae family, the latex from its leaves is a well-known and strong purgative, providing a similar therapeutic endpoint for constipation, though through different phytochemicals (anthraquinone glycosides).
