peyote (sh) and dermatitis (sh)


peyote (sh)




Either of two species of the genus Lophophora in the cactus family, native to North America, almost exclusively to Mexico.

The body of the peyote cactus is spineless, soft, usually blue-green, and only 3 in. (8 cm) wide and 2 in. (5 cm) tall. The more common species, mescal (L. williamsii), has pink to white flowers. L. diffusa, more primitive, has white to yellow flowers and a yellow-green body. Well known for its hallucinogenic effects (primarily due to the alkaloid mescaline), peyote figures prominently in old and recent religious rituals of certain American Indian peoples. The sale, use, or possession of dried mescal buttons (flowering heads) or live plants is prohibited by law in many places.

dermatitis (sh)




or eczema

Inflammation of the skin, usually itchy, with redness, swelling, and blistering.

Causes and patterns vary. Contact dermatitis appears at the site of contact with an irritating substance or allergen. Atopic dermatitis, with patches of dry skin, occurs in infants, children, and young adults with genetic hypersensitivities (atopy). Stasis dermatitis affects the ankles and lower legs because of chronic poor blood flow in the veins. Seborrheic dermatitis appears as scaly skin, most often on the scalp (dandruff) and areas rich in sebaceous glands. Neurodermatitis is apparently caused by repeated scratching of an itchy skin area.
