Roots are used for impotency.

Roots are also used for chest pains, while dried ground rootbark is directly applied for toothache.

Bark is used as a tonic and blood purifier.

Monoamine Oxidase Inhibitory Coumarin from Zanthoxylum schinifolium :
A methanol extract of Zanthoxylum schinifolium stems at a concentration of 250 mg/ml showed potent inhibitory activity against monoamine oxidase (MAO) in a mouse brain. Activityguided separation and purification of the extract yielded lacinartin (1) as an active coumarin compound. Lacinartin showed sig- nificant inhibitory effects on MAO in a dose-dependent manner. The lC50 value on MAO activity was 9.2mM. The MAO-A (IC50 value, 5.7 mM) sensitivity to lacinartin was greater than that of MAO-B (IC50 value, 28.6 mM). An enzyme kinetic study revealed that lacinartin inhibited MAO activity by a non-competitive mode.
