How It Works

Botanical names:
Lomatium dissectum

How It Works

According to obscure sources, lomatium is reputed to have antiviral effects. One source suggests the constituents tetronic acids and a glucoside of luteolin may be potentially antiviral.2 However, little is known about how these compounds act or if other ones might be as important.

How to Use It

Lomatium extracts with the resins removed (often called lomatium isolates), 1–3 ml per day, have been recommended. Lomatium tincture, 1–3 ml three times per day, can also be used, but it may cause a rash in susceptible people. The tincture should not be used unless a very small amount of it is first tested for a reaction. However, even very small amounts can cause a reaction in sensitive people.
