A Note on this Materia Medica

Each botanical write up is compiled from my notes taken at various herbal schools, favorite herb books and personal experience. This information is for general health and information only. Nothing contained in the herbal monographs should be taken as medical advice. People passionate about living a holistic lifestyle and the uses of plant medicine will find something of interest here. This project is dedicated to my love of herbs and a place where I can share with others who feel the same. This is a work in progress and as I go through my notes and continue my studies I will be updating and adding new herbs. Thank you for being here!

Habitat and Botanical Description: 

Usnea is not a plant, but a lichen, a symbiotic relationship between an algae and a fungus. Usnea can be found worldwide with localized concentrations of individual species. Moss like in nature, it can be found hanging on the branches of conifers, oaks, fruit trees throughout the northern hemisphere and prolifically in the PNW as it prefers moist habitat with high humidity, fog or rain. Usnea lichen has long, flexible gray green threads and readily identifiable by its elastic central cord running through the middle. A characteristic unique to this genus.

Medicinal Uses:

Usnea is energetically cooling and drying and can be used at the first signs of heat, inflammation, and infection. The constituent usnic acid is found in all lichens contains of anti-microbial and antibiotic properties which makes it a great addition to your home apothecary. Usnea has an affinity to the lungs. It has an ability to relax smooth muscles, especially in the bronchi for colds, flu, pneumonia, bronchitis, tuberculosis. Usnea contains immune modulating polysaccharides beneficial for lingering coughs and colds. Usnea disrupts the cellular mechanics of gram-positive bacteria like streptococcus and staphylococcus but leaves our natural microbiota unharmed. There is little to no effect with gram-negative bacteria such as e coli.

Usnea also has an affinity for the urinary tract.  Its anti-septic properties disinfect but contain no resins and tannins that can irritate or exacerbate infections. Usnea has a diuretic effect and strong antibacterial properties that help issues like bacterial vaginosis. Usnea should be consumed internally as well as externally with sitz bath in these circumstances. It can be used in the same way for its anti-fungal properties on the skin and genitals. Common female reproductive imbalances like vaginal candida and combines well with yerba Santa or sweet root and other strong anti-fungal in tea or tincture form taken internally and added to the bath. Usnea is beneficial following the use antibiotics to prevent the growth of candida. When preparing a douche, soak the usnea in alcohol then decoct in water (or 1/2 oz tincture to16 oz water).  Strain well. The common name old man’s beard or witch’s hair points both to its appearance and to its use, following the doctrine of signatures as a tonic to the hair and the scalp. Useful for dandruff, cradle cap, beard rot, crotch rot and jock itch.

Usnea is a vulnerary and an overall all-purpose first aid remedy. All usnea species can be used interchangeably. To use usnea on a wound, dilute the tincture, use the powdered herb, prepare a wash made from tea, or in a salve.

Harvesting:

Harvest the entire thallus of the lichen at any time of year hanging from the branches and trunks of their tree hosts. Lichens are very slow growing so as a sustainable practice, the intact lichen should be collected from the forest floor after heavy winds, leaving what remains in the trees to continue to grow. Recently fallen or partially dried material is generally considered fresh because of its strong antibiotic and antibacterial properties. Be sure to harvest away from roadsides as lichens are accumulators of heavy metals. They are pollution sensitive and are not found growing significantly in cities for this reason. An abundance of lichen is often an indicator for the environmental health of the area.

Contraindications:

Usnea should be used with caution as it does have some fever suppressing attributes. Little to no effect on gram – bacteria. When simmering alcohol to prepare tincture it is best to use an electric stove. There have been some reports that’s the constituent usnic acid may cause hepatotoxicity, but the evidence is inconclusive.
