Ma Chi Xian马齿苋
Portulacae Herba · Purslane
Overview
The fleshy, sour-tasting succulent eaten as a vegetable from China to the Mediterranean, and one of the standard herbs for damp-heat in the intestines. Sour and cold, it clears heat-toxin and cools the blood; its best-known use is dysenteric diarrhoea with blood and mucus, urgency and burning. Pounded fresh or decocted as a wash, it is equally at home on the skin, settling hot, weeping, itchy rashes and insect bites.

Cautions
Sour and markedly cold: not for a cold, weak Spleen and Stomach, nor for diarrhoea that is watery and cold rather than hot and urgent. Purslane is high in oxalate, so anyone with a history of oxalate kidney stones should limit it. Blood in the stool always needs a diagnosis — it should be investigated conventionally rather than treated as a passing complaint, and dysentery with high fever or dehydration is a medical emergency. It is contraindicated in pregnancy. Our dispensary data flags no toxicity and no allergy risk.
Contraindicated in pregnancy: Contraindicated in pregnancy — it is slippery and downward-draining, and is traditionally held to stir the uterus
