Shirisha Powder for Eczema

          Eczema is a term that denotes different types of allergic skin inflammation usually of chronic origin. The symptoms of eczema commonly include itching, reddened and dry skin. Since the skin is itchy, prolonged scratching leads to a leathery thickening of the skin. Cracking and weeping of the skin may also occur and open sores may become infected.

Causes of eczema

          Though the causes of eczema have not been fully determined, the following list provides some insight as to the triggers for eczema:

  1. Family history: there is a genetic component to this disease.
  2. Irritants: exposure to industrial solvents, chemicals, vehicle lubricants, soaps, cement, detergents, cleaning products, rubber gloves and even cosmetic lotions and creams, etc.
  3. Allergy: strong reactions to some allergens can cause violent skin eruptions.
  4. Chronic dry skin: dry skin that is left un-moisturized can develop into eczema especially in cold weather.
  5. Poor circulation: more common in the elderly and affecting lower limbs.
  6. Obsessive compulsive disorder: habitually rubbing or scratching skin.
  7. Reaction to an infection: some fungal, parasitic, bacterial and viral infections can cause localized eczema.
  8. Stress: stress causes the immune system to be compromised causing increased susceptibility to skin conditions.
  9. Diet: some have found modification to diet extremely useful in maintaining remission periods.
  10. Unknown factors: some forms of eczema are triggered by unknown reactions of the immune system.

          Though eczema is very difficult to control, allergic component of eczema can be controlled to an extent by regular internal and external use of Shirisha, which is widely mentioned in Ayurvedic classics and used in clinical practice at large by traditional practitioners. Some do’s and don’ts include:

  1. Excessive intake of sour, salty and pungent foods and drinks, curd, milk, jaggery, sesame seeds, black gram and alcoholic beverages should be avoided.
  2. If there is oozing from the eczema site, efforts should be made to keep the site clean and dry. Whereas in dry eczema it is always advisable to keep the affected area moist and smooth with vaseline or an oily preparation.
  3. Avoidance of aggravating factors of eczema, and eating simple, soft, easily digestible food helps. Edible items of bitter taste; regular use of honey and peace of mind help in management of eczema.

Shirisha (Albizzia lebbeck Benth.)

          Shirisha consists of the powder of the bark of Albizzia lebbeck, a large, deciduous tree, which is found all over India up to 900 meters in the Himalayas. It grows wild especially in the moist and dry deciduous forests. The bark of the tree is thick and dark or brownish grey with numerous short irregular cracks. The seeds are oval or oblong, pale brown, smooth with a hard testa. Shirisha is described as one of the best Vishaghna (anti-toxin) drugs in Ayurvedic texts1. Clinical studies show that Shirisha acts as an antidote to animal poisons which are histaminic in nature and are also responsible for the production of allergic dermatitis, urticaria and anaphylactic shock2.


          Shirisha powder is prepared from its bark for oral use and decoction for washing the affected skin.
