Ash plant for Herbal Naturopathy: properties, benefits, uses, side effects

Ash is a medicinal plant known since ancient times for its laxative, diuretic, anti-inflammatory, antirheumatic, antiarthritic property and for its sap, manna. Let’s find out better.

Properties and benefits of Ash

Ash is a medicinal plant with strong medicinal properties. The fruits, leaves, roots and bark of ash have slightly laxative, diuretic, anti-inflammatory, antirheumatic, antiarthritic properties.

These properties are due to the presence of coumarins (fraxin, fraxetine, frassinol, esculetin) and flavonoids (quercetin, rutin, hydroxyframoside), which inhibit the production of endogenous inflammatory mediators such as prostaglandins.

From the sap that flows from the wounds of the ash trunk is extracted manna, known since ancient times. Manna is a natural laxative with different therapeutic properties, such as: fluidifier, expectorant, emollient and cough suppressant, decongestant and calming in chronic bronchitis, laryngitis and pharyngitis.

Manna is also used in cosmetics for its characteristic of making the skin smooth and soft and reducing wrinkles.

How to use

Ash is used against joint pain, cellulite and water retention. Its leaves also have an antidiuretic, antirheumatic action and are useful against difficult digestion.

With ash you can make an infusion (2 g of dried leaves in 100 ml of boiling water) or a decoction (2 g of bark in 100 ml of boiling water).

The bark of ash is useful against rheumatism, arthritis, gout and fever. The fruits, on the other hand, have a laxative action.
