What is it
The Oak (Quercus robur), also called Farnia, is a majestic tree, which can even reach 50 meters in height and is characterized by slow growth and proverbial longevity.
Thanks to the presence of tannins in the bark it was used in ancient times for the treatment of diarrhea, hemorrhoids and wounds.
Activities
The main activity of the oak is astringent. It also exerts healing action, anti-inflammatory (especially on the mucous membranes), slightly antiseptic, sebum-regulating, anti-ulcer and antisecretory.
Why is it used
Oak extract is used in many areas in which astringent, anti-inflammatory and healing activity is useful, such as diarrhea, gingivitis and inflammation of the oral cavity, gastric acidity and also sores and skin lesions, fistulas and fissures, hemorrhoids and varicose veins.
It is also used against dandruff.
How to use it
It can be used in different forms:
| Young bark extract | 1% for indoor use, 10% for outdoor use |
| Mother tincture prepared from fresh bark | In alcoholic solution (at 65°) or aqueous (for external use, at a concentration of 10%) |
Another mode of use is in decoctions and herbal teas, in case of gastrointestinal infections and diarrhea.
Effects
Toxicity is very low. Side effects may be related to prolonged use and/or high doses and consist mostly of nausea, vomiting and gastrointestinal inflammation due to tannins.
Precautions
The use must be under medical supervision. There are no special warnings outside of a use with the recommended methods.
Interactions
Interactions can occur with alkaloids and heavy metal salts (in the past, oak extract was used as an antidote for this type of poisoning).
