Milk Thistle in Ayurveda: A Comprehensive Overview
Botanical Name:Silybummarianum
Common Names: Milk Thistle, St. Mary’s Thistle, Blessed Thistle
Sanskrit Name (commonly used in Ayurveda): While Milk Thistle is not traditionally native to Indian Ayurveda, it is sometimes referred to as “DugdhaKantak” or is used under its botanical name, Silybummarianum, in integrative Ayurvedic practice.
Ayurvedic Perspective on Milk Thistle
Milk Thistle, traditionally used in Western herbalism for over 2,000 years, has gained increasing recognition in modern Ayurveda due to its potent liver-supportive properties. While not originally listed in classical Ayurvedic texts, its pharmacological actions and energetics can be interpreted using Ayurvedic principles.
Pharmacological Properties in Ayurveda
- Rasa (Taste):Tikta (bitter), Kashaya (astringent)
- Veerya (Potency):Sheeta (cooling)
- Vipaka (Post-digestive effect):Katu (pungent)
- Guna (Qualities):Laghu (light), Ruksha (dry)
These properties contribute to its detoxifying, anti-inflammatory, and hepatoprotective actions in the body.
Action on Doshas
Milk Thistle helps balance the Pitta and Kaphadoshas due to its bitter and astringent tastes and cooling nature. It may mildly aggravate Vata when used in excess, due to its drying quality.
- Pitta: Reduces (due to its cooling and bitter properties)
- Kapha: Decreases (because of lightness and astringent and bitter flavors).
- Vata: Could rise as a result of lightness and dryness.
Key Constituents (Phytochemistry)
- Silymarin complex (main active compound): a group of flavonolignans known for hepatoprotective effects.
- Silibinin (Silybin): Most bioactive part of the silymarin complex.
- Flavonoids and polyphenols: Contribute to its antioxidant and anti-inflammatory actions.
Traditional and Modern Uses
Milk Thistle is renowned for its effects on the liver and digestive system, and is used in Ayurvedic-inspired formulations for a range of disorders, especially those involving excess Pitta or toxins (Ama).
