Oak in Herbalist: Properties of the Oak
The oak can be used under medical prescription for its disinfectant and anti-inflammatory activity in the treatment of diarrhea (decoction or capsules).
Biological activity
The oak, thanks to the tannins contained within its bark, is able to exert an astringent, anti-inflammatory, anthelmintic, antiviral and disinfectant action.
Thanks to its marked astringent action, the oak is used internally for the treatment of diarrhea (a use that has been officially approved).
Furthermore, the extract of oak taken internally in small doses is used as a stomachic remedy to favor, therefore, a correct digestion, although this use has not been approved.
Oak against diarrhea
As stated above, thanks to the astringent and disinfectant activity conferred by the tannins, the oak can be used as a remedy to combat non-specific diarrhea.
For the treatment of this disorder, the oak must be used internally and is usually taken in the form of a decoction.
Usually, it is recommended to take two or three cups of decoction per day (freshly prepared each time, soaking 1 gram of drug in cold water and then quickly bringing it to boiling). The maximum recommended dose is 3 grams of drug per day.
Oak against skin and oropharyngeal inflammation
The anti-inflammatory and astringent activities exercised by the oak are not only useful at the gastrointestinal level, but are equally effective at the level of the skin and mucous membranes. Therefore, this plant is a valid aid in the treatment of inflammations of the skin and mucous membranes of the mouth and pharynx.
For the treatment of the aforementioned diseases, the oak is used externally, generally in the form of a solution for rinsing and gargling. This solution can be prepared by boiling two teaspoons of finely divided drug in about three cups of water.
