Product Overview

  • Herbal Supplement
  • Non-Irradiated
  • Kosher
  • Supports Healthy Liver Function

Milk thistle seed is used as a liver tonic, to "support healthy liver function" and overall well being. The hard, dark-colored seeds are ground and used to make a tea or tincture, encapsulated, or added to foods. The whole seeds are also sometimes added to foods.

Suggested Use

Grind milk thistle seed in a coffee grinder or spice mill, and add the ground seeds to shakes or cereals. Or encapsulate the ground seed, if preferred. To prepare milk thistle tea, add one cup of boiling water to one teaspoon of ground seeds, and steep for 15 minutes.

The ground seeds can also be prepared as a tincture using a menstruum of 50% alcohol and 50% water (or 100 proof vodka).

The whole seeds can be toasted and added to salads, breads and cereals.

Milk thistle seed has been extensively researched for its protective effects on the liver. While formulations with concentrated levels of silymarin (70 to 80%) are being studied as a treatment for various liver problems (especially in Europe), the whole seed, with its much lower silymarin levels, is used as a liver tonic, to "support healthy liver function" and overall well-being. Chronic drug and alcohol abusers also use milk thistle as a supporting herb.


The Botanical Safety Handbook* classifies milk thistle seed as:
Class: 1: Herbs which can be safely consumed when used appropriately.
Per the German Commission E Monograph** for milk thistle seed, there are no known contraindications, side effects or drug interactions.

Tough to eat

Posted by 4783196213990435832 on Nov 30, 2016

I recommend getting this stuff already ground. I tried putting it in my grinder and it really didn't want to cooperate with me.

Put in my green smoothie

Posted by LantauMama on Oct 24, 2014

I put these in my green smoothie every morning - the Vitamix grinds the up perfectly so they are not even noticeable. Good for my liver according to my naturopath whom suggested I take it daily.

Good Tea; hard to crush seeds

Posted by 5142192348794453440 on Nov 06, 2013

I like milk thistle tea but I didn't realize how challenging it was to crush the whole seeds. I will not get them again. Like milk thistle tea good product.
