Milk Thistle Tincture (Silybum marianum)

Alcohol-extracted tincture of Silybum marianum, Milk Thistle, the most-studied Western liver-supporting herb. The tincture format is significant for Milk Thistle because the active silymarin complex is poorly water-soluble - alcohol extracts it more effectively than tea, making the tincture a more potent delivery than tea preparations.

Why Tincture?

Milk Thistle's silymarin complex is poorly water-soluble - meaning that traditional tea preparations extract relatively little of the active compound. Alcohol extraction is significantly more effective; the tincture format delivers more of the active silymarin per dose than tea. For maximum potency, standardized extracts (with specific silymarin concentration) are widely available; the alcohol tincture is an intermediate between tea and standardized extract.

How to Use Milk Thistle Tincture

Typical use: 30-60 drops in a small amount of water, 1-3 times daily. Take with meals (silymarin absorption may improve with food, particularly fatty meals). Effects build over weeks of consistent use rather than from single doses.
