Lebanese Oak
Quercus libani
Quercus libani, commonly known as the Lebanese oak, is a tree native to the Mediterranean region. While its traditional medicinal uses are not well-documented, it has been observed that Q. libani faced significant decline in the Northern Zagros forests of Iran, possibly due to environmental stressors such as drought and charcoal disease. Scientific evidence indicates that Q. libani leaves can be beneficial for ruminants when treated with Klebsiella pneumoniae bacteria, which increases their nutritive value without altering leaf structure. However, there is no substantial scientific evidence supporting its use in traditional medicine or any known safety concerns or drug interactions related to this plant.

What the science says
- Drought stress intensified the negative effects of charcoal disease on both Quercus infectoria and Q. libani seedlings, with Q. libani showing more pronounced changes in antioxidant markers.
- Quercus libani faced the most severe decline among three oak species monitored in the Northern Zagros forests of Iran.
- Three Prionchulus species, including one new species, were described from a natural ecosystem in Lorestan Province, Iran.
- Bacterial treatment with Klebsiella pneumoniae increased the crude protein content and improved fermentation parameters in Quercus libani leaves without changing other chemical compositions.
