As a thin girl it's really hard to gain volume...

Wikipedia had this to say about extracting the actives:

The sarsasapogenin saponin can be extracted from the dried powdered root with 95% ethanol. After removal of the fat from the resulting gum, the glycosidic linkage is hydrolyzed with hydrochloric acid (approx. 2 M) and the resulting crude steroid is recrystallized from anhydrous acetone. The yield of pure sarsasapogenin from 225 kg of Smilax root is reported to be about 450 grams.

Thanks for sharing. That looks very professional. Maybe alcohol extract is a simpler home made version? I’ll just use more drops each time when massaging. The liquid extract sold online only is made from only 18 g Zhimu. That makes it not super attractive to me over an easily home made extract.
