Teasel is a potent astringent and is often used as a diuretic and to arrest diarrhea. It stimulates the appetite, improves digestion, and, like other members of the thistle family, aids rejuvenation of the liver and gall bladder. However, it is also regarded as useful in the treatment of Lyme disease. Matthew Wood devoted an entire chapter to it in one of his books and it is one of the ingredients in the Stephen Buhner formula we produce under the name of Spiro Pro. Use very cautiously and check the directions before dispensing.
