Tetrahydroberberine is a different kind of living thing that can be extended and divided into parts. Tetrahydroberberine is a kind of effective D2 receptor antagonistic force. Tetrahydroberberine has the ability to strengthen the stomach and relieve the pressure on the stomach[1][2][3].
Tetrahydroberberine (100 μM) blocks K(ATP) channels in sharply isolated dopaminergic (DA) neurons in rat substantia nigra pars compacta (SNc) and restores membrane hyperpolarization induced by 1 μM rotenone (HY-B1756)[3].
Tetrahydroberberine (30 μg/kg; IV) causes a dramatic increase in gastric regulatory capacity in beagle dogs, significantly enhances gastric contractility and shortens contraction intervals in rats, and enhances gastric motility function in the upper gastrointestinal tract[1].
