利用:種は、食べれる。山椒に似ている。若い葉っぱも食べれる。

Medicinal usage :

The pericarp is anaesthetic, diuretic, parasiticide and vasodilator[176]. It is used in the treatment of gastralgia and dyspepsia due to cold with vomiting, diarrhoea, abdominal pain, ascariasis and dermal diseases[176]. It has a local anaesthetic action and is parasiticide against the pork tapeworm (Taenia solium)[176]. The pericarp contains geraniol. In small doses this has a mild diuretic action, though large doses will inhibit the excretion of urine[176]. There is a persistent increase in peristalsis at low concentration, but inhibition at high concentration[176]. The resin contained in the bark, and especially in that of the roots, is powerfully stimulant and tonic[82].

薬効:  果皮は麻酔、利尿剤、 寄生虫駆除剤、 そして血管拡張薬となる。
胃痛と消化不良に効く。有鉤条虫 (Taenia solium)の駆除に効く。 果皮にジェラニョール(geraniol) があります。摂取量が少量の場合、利尿作用がありますが、多量に摂取すると反対に作用し、尿が出なくなります。皮などからの脂は、強い興奮剤と強壮剤となります。
