Usnea is one of the gentlest yet strongest immune tonics in the herb world.
Usnea is a lichen; a combination of an algae and a fungus growing together. Also known as Old Man’s beard, it grows in little hair-like tufts, with the green algae covering the white string like fungus.
The way to identify Usnea is to pull a string apart and look for this white thread.
It has anti-inflammatory and analgesic properties.
Water does not extract the usnic acid, which is the primary medicinal component of Usnea; alcohol tincture is necessary.
