Lomatium dissectum (Syn. Leptotaenia multifida/dissecta)
Wild, celery-like herbaceous perennial native to the Great Basin and other drylands of the West. In nature, Lomatium grows on sunny slopes in rocky soil. Sow in outdoor nursery bed in the fall or midwinter. Expect germination in cold soil in spring. Naturally low germ rate. Plant 1 foot apart. Grows to 3 feet tall.
This is our most important indigenous, antiviral herb from the American Pacific Northwest; works where other antivirals fall short. The root is the part used.
Please note: Since many people are thinking that Lomatium is the best protection from "Avian Flu" and other newsworthy threats of pandemic influenza, then I thought to add a little more information on Lomatium history and using Lomatium in therapy. Probably our strongest native antiviral herb. During the last pandemic, first nations peoples were smart enough to use the fresh or dried root of Lomatium and survived unharmed while white folks who didn't know about lomatium did not survive. In therapy, lomatium is best to use with a liver/urinary stimulant such as dandelion to help avoid lomatium rash side effect. The lomatium rash side effect is a bothersome proliferation of raised red spots, not itchy, that usually appears on the torso, and lasts sometimes as long as three weeks after discontinuing use of the herb. When lomatium is taken along with dandelion and at recommended dosage, then this rash rarely occurrs. Meanwhile, even while the rash is doing its thing, the viral load in the blood is wiped clean...
Another note: Actually, I'm a little more excited about Baical Skullcap (Scutellaria baicalensis) for treatment of pandemic diseases. My experience is that the root of this plant, which has been used in Chinese medicine for a very long time as the herb Huang-qin, is extremely effective for treating contagious flu-like maladies. There is really no better anti-infection agent in herbalism, to my knowledge. The herb is more effective if grown in poor, sandy soil. Added advantages of Huang-qin over Lomatium are 1) lack of side-effects, 2) quick to germinate and easily grown throughout the temperate US 4) prettier 5) and can be harvested in the fall of first or second year 6) no side effects.
