Yohimbine
An alkaloid that’s the active principle in yohimbe (bark of the African tree, Pausinystalia yohimbe). Yohimbine hydrochloride is sold as a prescription drug for erectile dysfunction. Yohimbine is also used to treat xerostomia (dry mouth).
Yohimbine (either in standardized form or as yohimbe bark extract) is frequently used in “male enhancement” products, as well as fat loss supplements. Yohimbine stimulates lipolysis by increasing blood flow in adipose tissue and blocking the activation of a 2-adrenoceptors on fat cells…although it works better in theory than in fact.
Yohimbine is associated with a number of adverse effects, and should be avoided by individuals with hypotension (low blood pressure), diabetes, and heart, liver or kidney disease.
See David Tolson’s article “Yohimbine Science” for more information.
Ellagic Acid
A polyphenolic antioxidant found in a number of plant foods, such as raspberries, pomegranates and walnuts. Ellagic acid is released from “ellagitannins” during digestion and/or food processing. Ellagic acid has shown anti-tumor effects in animal and cell culture studies, but it’s not known if there are similar effects in humans.
Ginger
Officially known as Zingiber officinale. Although the edible part is often called a “root” – it’s actually a rhizome, or underground stem. Ginger has both culinary and medicinal uses. The rhizome contains essential oils and bioactive components called “gingerols” and “shogaols” that have anti-inflammatory, anti-microbial and anti-tumor effects. Ginger is an effective treatment for nausea, as well as a mild thermogenic…which is why it’s frequently added to fat loss supplements. Other potential health benefits include improved glucose control + serum cholesterol/blood lipid levels.
