What is purslane? What is it used for?

Although regarded as a weed in the United States, purslane is a well-known plant able to tolerate almost any kind of soil or weather. It grows up to 20 inches high, with purple or green stems; greenish, tear-shaped leaves; and yellow flowers that open only when sunny.

The aerial parts of the plant (branches, leaves, flowers, etc.) are used medicinally by being washed, steamed (or treated with boiling water), and left to dry in the sun.

In traditional Chinese medicine, purslane is used to remove toxic heat and substances, and to arrest bleeding. Among the Western conditions purslane treats are dysentery; boils and sores; eczema; hemorrhoidal bleeding; and abnormal uterine bleeding.

How much purslane should I take?

The amount of purslane being used depends on the condition(s) being treated. Many practitioners recommend 9-15 grams of dried purslane, or 30-60 grams of fresh purslane for oral administration. Larger amounts can be grounded into a paste to apply to the skin.
