Should I take it?
Lobaria pulmonaria is a member of the lichen family. Lichens are fungus plants that grow together with algae--usually on trees or rocks. Lobaria pulmonaria is a large, flat, greenish or brown lichen that vaguely resembles oak leaves. It grows on broad-leaf trees, especially oaks, in cool, mountainous regions of Africa, Australia, Europe, and North America. Its spongy texture and many-lobed appearance reminded ancient healers of the human lungs, so it was used widely to treat respiratory ailments such as asthma and coughs. Today, Lobaria pulmonaria is relatively rare--an endangered species in many parts of the world.
To be used in herbal and homeopathic medicine, the whole Lobaria pulmonaria lichen is dried and crumbled into light-brown flakes. It may also be powered and made into tablets or capsules. Dried Lobaria can be steeped in hot water for a tea or it can be made into a liquid extract when soaked in alcohol.
Dosage and Administration
No recommendations for dosing amounts or intervals are available in the scientific literature. If Lobaria pulmonaria is used, the directions on the package that is purchased should be followed.
Summary
Lobaria pulmonaria may have a slight relaxing effect on the lungs and it also seems to make mucus less thick and sticky. It has been taken orally for asthma, bronchitis, and coughing. Currently, both prescription and non-prescription drugs are much more effective than Lobaria pulmonaria, so its use is discouraged.
Risks
No absolute prohibitions are placed on the use of Lobaria pulmonaria in recommended amounts. However, since very little is known about it, taking Lobaria pulmonaria is not recommended.
Side Effects
Even though no side effects have been reported with the use of Lobaria pulmonaria, its use is not recommended.
Interactions
No interactions have been reported between Lobaria pulmonaria and prescription drugs, non-prescription drugs, other herbal supplements, or foods. However, because few reliable studies of Lobaria pulmonaria have been conducted, not all of its possible interactions with drugs, foods, and other dietary supplements may be known.
