Mistletoe (Part Two): Druids And German Cancer Patients Swear By It

Modern interest in mistletoe as a possible treatment for cancer began in the 1920s. For centuries, it had been used as something of a cure-all, but when mistletoe's immunostimulant properties were confirmed, the Druids' reverence for the healing power of this parasite got some scientific validation. Since then, lots of studies have been done in Germany, where many cancer patients augment conventional treatment with mistletoe extracts. In the lab, it kills certain cancer cells, while boosting the

Mistletoe (Part One): A Parasite That Can Hurt Or Heal

It turns out that the poison of the calabar bean is absorbed in the mouth, where a guilty person might try to hold the beans, to avoid swallowing. For the guileless who swallowed them whole, the emetic

Usnea: Bearded Medicine

You might have brushed by it in the forest, where this hairy-looking symbiosis between algea and fungi perches on tree limbs. The look of the lichen usnea explains its nicknames: "old man's beard," "tree's dandruff," "women's long hair," and "beard lichen." For centuries, it's been considered a handy medicinal. People grab some to dress wounds, or take it internally for infections or oral inflammation. But in the 1990s, when manufacturers of weight-loss drugs started adding sodium usniate (usnic
