Can anyone explain the difference between Ephera Sinica, Ephedine HCL and pseudoephedine? Thanks.
ephera sinica is a spelling error, but if you meant ephedra sinica, consider it a genus (plant family name), also known as Ma Huang, Mao and a few other names. The ephedra alkaloids are extracted from these plants and standardized for a “x” amount of ephedrine (1 of 5 alkaloids).
Ephedrine HCL is synthetic ephedrine and pseudoephedrine is an isomoer of ephedrine that is used in cold medicines.
