MEDICINAL PROPERTIES OF OAK

NATURAL REMEDIES WITH OAK

Oak medicinal properties are derived from its richness in tannins and flavonoids that provide it with astringent, antiseptic, anti-inflammatory and hemostatic properties.

What is an astringent?

It is called astringent to any substance that constricts body tissues. It is primarily used in two ways:

- Internally to reduce secretions, reduce swelling and stop bleeding.

- Externally to "dry" skin, tightening the tissue or blocking fluid.

The astringent properties of oak are mainly due to the presence of tannins (gallic acid) and catechins.

What is an hemostatic?

It is called hemostatic to any compound capable of retaining blood flow. In natural medicine the hemostatic properties of certain plants are used to stop bleeding.

In natural medicine these properties are used for the following conditions:

OAK BARK PREPARATIONS FOR INTERNAL USE

Oak bark decoctions for the digestive system

Oak bark decoctions are suitable for the digestive system abnormalities as they can neutralize excess secretions which can cause numerous problems such as:

- Diarrhea: This plant can stop diarrhea by reducing the excess of fluid in the gut, which is useful if colitis or diarrhea. (Decoction of a teaspoon of ground bark for each glass of water. (5 g.) Drink 3 cups a day).

For childhood diarrhea some acorns can be toasted and pounded into a powder. Make a decoction of 3 gr. per cup of water.

- Gastritis: It helps improve the symptoms of the disease, by acting on an inflamed gastric mucosa. Gallic acid, besides being astringent, has anti-inflammatory properties because of flavonoids. (Decoction of a teaspoon of ground bark for each glass of water. (5 g.) Drink 2 glasses)

Do not exceed the dose and avoid treatment for ulcers because this plant can aggravate the disease. If a worsening, stop taking it and consult a doctor. The plant contains beta-sitosterol having ulcerogenic properties.

- Intestinal bleeding: People with intestinal bleeding can take the same mixture, provided that they have been diagnosed by a doctor and their ulcers do not present an evil character

- Urinary incontinence: The astringent properties of this plant can avoid this derangement (Decoction of a teaspoon of bark per cup of water for 10 minutes (three small glasses a day)

- Vaginal flow: The preparation above may be useful for the treatment of vaginal discharge.

Oak bark remedies for external use

Wealth in tannins and flavonoids gives the bark of this plant antiseptic, anti-inflammatory, astringent and hemostatic properties, which can be exploited for treating a number of conditions including:

- Pharyngitis: It reduces inflammation of the pharynx and helps eliminate germs that cause inflammation. (Decoction of 5 0 6 tablespoons of crumbled dried bark per liter of water. Make gargling)

- Sore throat: The same treatment is suitable to gargle in order to treat swollen tonsils.

- Rectal or anal problems: These same properties can be helpful in the treatment of rectal problems such as healing of hemorrhoids (Use the previous preparation to mix with water and perform sitz baths). Also for anal fistulas. (Decoction of a teaspoon of dried bark per cup of water. Wet a towel with the liquid and apply on fistula).

- Problems of the gums: The gums are body tissues that cover the teeth and portions near jaws. These tissues are subject to possible inflammation (gingivitis) with a clear disposition to bleeding (bleeding gums). (Mouthwashes made from macerating one tablespoon of fresh bark in a liter of red wine for 4 days help reduce gum inflammation and stop the outflow of blood)

- Mouth sores: Same rinses may be useful in the treatment of mouth sores.

- Nosebleeds: Oak is one of the best hemostatic, able to stop the flow of blood. This property can be used to stop nosebleeds in the even of epistaxis or frequent episodes of bleeding from the nose. (Crumble a bit of dry oak bark. Convert it into powder with a coffee grinder. Take a speck of dust between your fingers and insert it into the nose.)

- Cracks in the skin: The astringent properties of oak help to close the cracks in the skin in people who are prone to the formation of these grooves when their skin is very dry - chapping, cracks on breasts, cracked anus, etc. (Decoction of a spoonful of dried bark per cup of water. Apply the liquid to the affected area two or three times daily)

- Chilblains: Its astringency may be suitable for the treatment of chilblains (decoction of 200 g of dried bark per 4 liters of water for ¼ hour. Cool and realize hands or feet baths with the resulting liquid)

- Inflammation of the vulva: Very useful in the treatment of vulvitis. (Make vulva baths with the liquid from the decoction of a spoonful of dried bark per cup of water.)

Collection and preservation of oak bark and leaves

Oak bark should be collected in spring and leaves in summer. They should be dried in the shade and stored in cloth bags in a cool, dry place.

Can oak consumption be dangerous?

Oaks and related plants of the genus Quercus have a very high amount of tannins, especially in the bark, where it can reach up to 20% and a smaller proportion in the leaves and fruits (acorns)

The tannins are irritating for the intestinal mucosa 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.

Internal preparations should never be taken in case of gastroduodenal ulcer. Treatments for internal use should not be prolonged longer than 4 days.

External use applications must not be performed on very large wounds or extend them beyond 15 or 20 days. Patients who present infections, fever or heart problems should not perform any baths treatments with this plant.
