Pangolins are remarkable creatures and they are endangered. Attempts to raise them in captivity have failed.
Like certain other (usually animal-derived) Chinese medicines, their legendary status is inflated. Furthermore, the market is flooded with plastic fakes.
No one needs pangolin scales in order to get well. Any trained herbalist can create an effective formula using other blood movers instead. If you buy this product, you fuel the demand for more. Stop using pangolin scales.
I provide the following information just for historical reference, and to understand, if you ever encounter Chuan Shan Jia in a prescription, what the intended action is, so that you can choose a suitable alternative.
