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.
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.
We also offer corydalis rhizome along with 20:1 and 4:1 extracts.
