==Chemical Composition==
The chemical composition of the volatile oil of Zanthoxylum rhetsa seed coat was analyzed by GC and GC/MS. Thirty-four compounds, accounting for 87.4% of the oil were identifed. The major compounds were terpinen-4-ol (32.1%), α-terpineol (8.2%), sabinene (8.1%), β-phellandrene (7.4%) and 2-undecanone (7.1%).<Ref name="Chemical Composition"/>

==How to plant/cultivate==
Seed - best sown as soon as it is ripe. Stored seed may requires up to 3 months cold stratification, though scarification may also help. Germination should take place within 6 months, though it might take another 12 months. Prick out the seedlings into individual pots when they are large enough to handle and grow them until large enough to plant out. Cuttings of half-ripe wood. Root cuttings, 3cm long, planted horizontally in pots. Good percentage. Suckers, removed when the plant is dormant, and planted direct into their permanent positions. <ref name="Cultivation details"/>
