* Siberian ginseng is one of only a handful of herbs that is an adaptogen, which means that it works to normalize bodily functions. It inhibits the adrenal stress response and works as an immune stimulant, particularly for fighting the effects of stress and [[depression]]. It aids the liver in detoxifying harmful toxins, including chemotherapeutic agents and radiation. Siberian ginseng also stimulates the activity of several immune system components: B and T cells, making it excellent for Chronic [[Fatigue]] Syndrome and other viral infections.
* Silver and silver compounds have an oligodynamic effect and are toxic for bacteria, algae, and fungi in vitro. The oligodynamic effect is typical for heavy metals, such as lead and mercury, but, among the elements that have this effect, silver is the least toxic for humans. But rgyria occurs in people who ingest or inhale silver in large quantities over a long period (several months to many years).
* [[Licorice]] may be used as a topical antiviral agent for shingles, ophthalmic, oral or genital herpes.
