My notes on Mahuang (from multiple WWW sources) are below.

 

It is said to enter LU & BL. Under ACTIONS (3), it says: Expel

Water; Diuretic~Antioedema (pseudoephedrine in raw Mahuang);

Antienuresis; Reduce Swelling (General);

 

Surely this indicates a KI (and possibly adrenal) effect?

 

Best regards,

Phil
