The Rauwolscine in Alpha-T2 is HCL i think is the synthetic form but the Rauwolscine (Rauvolfia Canescens L. [Leaf and Root]) is the plant
and a note this plant has few alkaloids in it so the label not says what USPlabs use in it.
Ten indole alkaloids, ajmaline, yohimbine, a-yohimbine, isoreserpine, corynanthine, deserpidine, reserpiline, isoreserpiline, aricine, and a new alkaloid, named lankanescine, have been isolated and identified from Rauvolfia canescens.
