Medicinal Parts:The most commonly used parts of the Sonchus oleraceus plant in medicine and food are the young leaves, stems, and the latex (milky sap).

• Leaves: The primary part used, consumed as a cooked green vegetable or used in decoctions. They are the source of most medicinal benefits.

• Stems: Young, tender stems are cooked along with the leaves.

• Latex (Milky Sap): Applied topically in traditional medicine for warts, skin ailments, and wounds.

• Whole Aerial Parts: Often harvested during the flowering stage for medicinal preparations.

4. Phytochemicals specific to the plant and their action.

Sesquiterpene Lactones (Sonchuside A & B): These are characteristic bitter compounds. Their actions include potent Anti-inflammatory, Antioxidant, and Cytotoxic (against certain cancer cell lines) effects. They are also responsible for the plant's bitter digestive tonic property.

Flavonoids (Apigenin, Luteolin, Quercetin derivatives): Common in Asteraceae, these compounds are strong free-radical scavengers. Their actions include Antioxidant, Anti-inflammatory, Cardioprotective, and potential Anticancer activities.

Phenolic Acids (Chlorogenic Acid, Caffeic Acid): These are widespread antioxidants. Their actions include Hepatoprotective (protecting liver cells from damage), Hypoglycemic, and Anti-inflammatory effects.

Terpenoids and Sterols (Taraxasterol): These compounds contribute to the plant's Hepatoprotective and Anti-inflammatory profile. Taraxasterol is also known for its wound-healing properties.

5. Traditional and Ethnobotanical uses covering the Medicinal uses.

Yakrit Vikara (Liver Disorders) & Raktashodhaka (Blood Purifier)

Formulation: Leaf decoction or cooked greens.

Preparation & Use: The leaves are consumed regularly as a cooked vegetable or a bitter decoction is made from the aerial parts. This is used traditionally to treat jaundice, liver congestion, and to "cleanse" the blood, manifesting as clearer skin.

Reasoning: The bitter principles and phenolic acids stimulate bile flow (cholagogue), aiding digestion and liver detoxification, while antioxidants protect hepatic cells, confirming its Hepatoprotective and antioxidant actions.

Jwara (Fever) & Daha (Burning Sensation)

Formulation: Leaf infusion or juice.

Preparation & Use: A fresh juice or light infusion of the leaves is given to help reduce fevers, especially those accompanied by a feeling of heat and inflammation.

Reasoning: The plant's anti-inflammatory and febrifuge properties, likely from its sesquiterpene lactones and flavonoids, help modulate the body's inflammatory response during fever.

Stanyajanana (Galactagogue) & Balya (Strength Promoter)

Formulation: Cooked leaves as a nutritious green.

Preparation & Use: Nursing mothers in various cultures consume the cooked greens in soups or stews to support healthy milk production. Its general nutritive content also makes it a tonic for weakness.

Reasoning: It acts as a nutritive tonic rich in vitamins and minerals. The mechanism for its galactagogue effect is not fully defined but is a consistent traditional use.

Vrana (Wounds) & Skin Afflictions

Formulation: Topical application of latex or poultice.

Preparation & Use: The white latex (milky sap) from the stem or leaves is applied directly to warts, cuts, or minor skin infections to promote healing.

Reasoning: The latex contains compounds with Vulnerary (wound-healing) and potential antimicrobial properties, helping to dry out warts and protect minor wounds.

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

Sonchus oleraceus is primarily a wild edible green, celebrated for its nutritional and medicinal value in many foraging cultures.

Liver-Cleansing Bitter Decoction

Purpose: To support liver function, especially after overindulgence or in cases of mild jaundice.

Preparation & Use:

• Take a handful of fresh or dried Sonchus leaves and stems.

• Boil in 3 cups of water until it reduces to 1 cup.

• Strain. This bitter decoction can be consumed in small doses (1-2 tablespoons) before meals. Due to its strong bitterness, it is often taken with a little honey.

Sautéed Sowthistle Greens (Dudhi ki Sabzi)

Purpose: A nutritious and detoxifying side dish.

Preparation & Use:

• Blanch the young leaves and tender stems to reduce bitterness.

• Sauté with cumin seeds, garlic, onions, and green chilies.

• Add turmeric and salt. Cook until tender. Serve as a side dish with rice or roti. Often cooked with lentils (dal) for a balanced meal.

Soothing Skin Latex Application

Purpose: For warts and minor cuts.

Preparation & Use:

• Break a fresh stem or leaf to exude the white, milky latex.

• Apply this latex directly onto the wart or around (not inside) a minor cut.

• Repeat 2-3 times daily for warts until they dry up. For cuts, apply once as a protective layer.

7. Disclaimer:

Sonchus oleraceus is generally safe when consumed as a food in moderate quantities. However, due to its potent bitter and diuretic properties, excessive medicinal use may cause stomach upset or interact with diuretic medications. The latex can be a skin irritant for some individuals and should not be ingested raw in large amounts. Pregnant and breastfeeding women should consult a healthcare provider before using it medicinally.
