Botanical Index No. 111

Black Alder

alnus glutinosa

Safety & Contraindications

Not covered. None reported in PDR.“Hazards and/or side effects not known for proper therapeutic dosages”. Regrettably, PHR and still PH2 report hypericin, probably meaning hyperoside. Hyperoside is what was reported in my CRC Handbook of Medicinal Herbs and in Hager’s Handbuch der Pharmazeutischen Praxis, ed. 2. So far, I have not yet found hypericin reliably reported outside the genus Hypericum, but hyperoside is widely reported.
