I'm not familiar with these two vines either. Through the search, I found that "Tetragona" belongs to the vine stem of Celastrus orbiculatus, also known as "Celastrus latifolia". Its functions are: expelling wind and removing dampness; Promoting blood circulation and dredging collaterals; Spatholobus suberectus belongs to the genus Chenopodium, which has the functions of relaxing muscles and tendons, activating collaterals, expelling wind and relieving pain. The two are not in the same category, but the effect is similar.

It's just that the standard in the process of drug production is unknown, and whether there is a situation that "broadleaf rattan" replaces "tetragonal rattan" is also unknown.

I can only answer to this extent at present, please forgive me.
