1. 性平, 味甘辛, 有小毒.

   Its nature is neutral, taste sweet and pungent, with mild toxicity. Castor seed is balanced in temperature and broadly usable, but its toxicity demands careful handling.

2. 治水脹腹滿, 催生.

3. 瘡痍疥癩, 去水癥浮腫, 尸疰惡氣.

   It addresses sores, scabies, and leprous lesions, removes water-mass swellings and edema, and dispels corpse-infusion and noxious qi. From skin ailments to deep-seated masses, it served as a versatile external remedy.

4. 葉似大麻而極大, 其子形如牛蜱蟲, 故以名之. 《本草》

   Its leaves resemble hemp but are much larger, and the seed shape recalls the cattle tick chong, hence the name. The character name bima itself was drawn from this seed's appearance. From Bencao.

5. 萆麻能出有形質之滯物, 善吸氣, 當是外科要藥.

   Castor draws out tangible obstructions and absorbs qi well, making it a key remedy in external medicine. It was especially prized topically for bursting boils and drawing out pus.

6. 鹽水煮, 去皮取仁. 《入門》

   Boil in salt water, then remove the husk and take only the kernel. This is the traditional processing that tempers toxicity and refines the medicinal nature. From Ipmun.
