High-Altitude Remedies

Only one herb has successfully passed the thin-air test: ginkgo biloba.


Besides acclimatizing and drinking plenty of fluids, can I use herbs to prevent altitude sickness? Which herbs are best?

Three separate studies have found that the herb is effective at preventing altitude sickness or reducing its intensity. It certainly won't work for every climber - people respond differently to herbs - but there's evidence it will help some. If you choose to try it, take 120 milligrams of ginkgo bilboa twice a day for 5 days before and during your ascent.
