Tetrahydropalmatine is the primary isoquinoline alkaloid of the Chinese medicinal herb, corydalis yanhusuo. This rare product contains over 98% pure
L-Tetrahydropalmatine. Even other pure THP products, if you can find them, are usually only about 80-95% pure. Pure THP is nearly tasteless. We also offer corydalis rhizome along with 20:1 and 40:1 extracts.
Corydalis Yanhusuo is an herb in the papaver family that is used in traditional Chinese medicine to invigorate the blood and relieve pain. It is also a particularly potent sedative that can be useful for insomnia. It is also reported to be a very effective natural pain killer without the addictive properties of many prescription drugs. Do not use if pregnant or nursing or without the approval of a doctor or healthcare professional.
