Usnea Lichen Uses and Benefits

Usnea is a kind of lichen that grows abundant on trees. Lichens are not plants, rather they are organisms composed of fungi and algae. Usnea lichens grow and thrive symbiotically with trees. It loves to thrive on sick or old and moribund trees, causing some people to blame usnea for the death of their trees. City trees rarely have usnea because it is very sensitive to air pollution.

Detailed Information on Its Benefits

The primary pharmacological content in usnea lichen is usnic acid. Usnic acid works against several gram-positive bacteria. Usnic acid inhibits a certain process called oxidative phosphorylation which is crucial for the bacteria’s metabolism. Usnic acid is yellow and bitter, thus deterring animals from grazing on usnea lichens. Because usnea lichen is highly medicinal, it is not recommended to be taken continuously. In traditional Chinese medicine, it is used routinely and periodically, only when a person exhibits certain ailments. It is used mostly as a topical medication, although some consume usnea internally. The use of usnic acid in weight loss is still disputed. Nevertheless, usnic acid is effective for the aforementioned purposes.

Like mushrooms, usnea lichen has the tendency to absorb and retain heavy metals in the environment. If exposed to vehicular exhaust, they would absorb its toxins after which they would cease from thriving. For safety purposes, acquire usnea only from a reputable seller.
