Why will herbal medicines block guai and herbal foods won ?
The medicines are concentrated. They are usually distilled or extracted and contain lots more of whatever plant it is. The liver processes the small amounts of salicylates in cooking to salicylate tagged with glycine, which apparently weakens the offender. When herbal medicines or plant concentrates are taken by mouth, there are often sufficient salicylates to overwhelm the liver’s capacity to glycinate and thus, the kidney gets a dose. So the herbal medicines are out, and herbal seasonings are in. The same principle holds for herbal teas. Herbal teas you buy in the grocery store are OK, because they’re weaker. Herbal teas from health food stores that are strong and medicinal are concentrated and too high in salicylates.
