I have been having ephidrine( 23mg)green tea and an aspirin(for heart) for about 2 weeks. Have added horny goat weed by prolab and about 20mins after my skin starts itching and feels very hot.

Horny goat weed:
Niacin 80mg
Horny goat weed 500mg
Maca 4:1 250mg
Tribulus terrestris 250mg
Gingko biloba extract 120mg
Yohimbe extract 100mg

Anyone know of why these reactiona would occur? Im thinking maybe yohimbe
