MEDICINAL PROPERTIES OF HOLM OAK
The medicinal properties of this tree come from its wealth in tannins, especially its acid. Tannins play a healing role in accelerating the wound healing and performing hemostasis (stopping the flow of bleeding).
The healing occurs by the formation of crusts by binding proteins with tannins and create a "dry" environment that prevents bacterial growth. By constricting blood vessels, they help blood clotting and, therefore, they contribute to the healing of wounds.
Besides, tannins have many more uses in herbal medicine for external use. These principles have applications in cosmetics and are useful for external skin care, helping to cure pimples, blackheads or contributing to the elimination of the fat in the skins that present excess of it, etc.

Toxicity of the oak
HOlm oaks and related plants of the genus Quercus (oak, kermes oak, etc) have a very high amount of tannins, especially in the cortex, where they can reach up to 20% and a smaller proportion in the leaves and fruit (acorns)
The tannins are irritating for intestinal mucosa and can cause vomiting and even ulcerations. It is recommended, therefore, to use preparations for internal use only under supervision of the physician and never exceed the recommended dose.
Preparations in case of gastritis or gastroduodenal ulcer should never be taken internally. The treatments of preparations for internal use will not have to extend over the 4 days. The use of preparations with this plant can be contraindicated in case of taking supplements of pectin, iron or some preparations with alkaloids.
For external use, the application should not be performed on very large wounds or extend them beyond the 15 or 20 days. Nor should baths with these preparations of this plant when patients present infections, fever or heart problems.
