Ashvagandha Powder


Malaise is a symptom of psychosomatic origin characterized by a general feeling of illness or lack of well-being and may be accompanied by discomfort, fatigue, lassitude, restlessness, loss of strength and lack of interest and drive. This symptom is usually a vague sense of ill-being and exhaustion seen in patients suffering from any significant febrile infection and metabolic or chronic disease.

The mechanism of development of malaise is not fully understood and probably it may result from excessive presence of reactive molecules called free radicals. These molecules cause oxidant injury to the body cells and inadequate supply of antioxidants in the diet lead to a decline in the levels of antioxidants with increasing age. The onset of malaise may be sudden or staggering depending upon the nature of the underlying disease.

Malaise associated with other symptoms indicates significant illness. The following is the list of conditions that mostly cause malaise:

  • (1) Acute infectious diseases like pneumonia, influenza, and viral fever.
  • (2) Chronic infectious diseases like AIDS, parasitic disease, hepatitis and tuberculosis.
  • (3) Organ-specific chronic diseases like heart failure, obstructive lung disease, kidney failure and liver disease.
  • (4) Autoimmune diseases like rheumatoid arthritis, sarcoidosis, and systemic lupus erythematosus.
  • (5) Endocrinal disorders like diabetes mellitus, dysfunction of the thyroid and adrenal glands.
  • (6) Various cancers like leukaemia, lymphoma, colon cancer and solid malignant tumours.
  • (7) Severe anaemia.
  • (8) Mental illness such as depression.
  • (9) Medication with anti-convulsant, anti-histaminic, psychotropic and beta-blocker drugs and multi-drug treatments.

Certain herbal medicines called Rasayana in Ayurveda are proven to have excellent anti-oxidant, immune-enhancer, anti-infective, anti-degenerative and anti-stress effects. Ashvagandha is one such medicinal herb, which helps in many ways in the restoration and maintenance of health and vitality and to reinforce the psychosomatic mechanisms involved in preventing and treating malaise of varied origin.

Ashvagandha Powder (Withania somnifera Dunal.)

Ashvagandha is a perennial shrub, found in waste lands, cultivated fields and open grounds throughout India. It is widely cultivated in India. The roots are collected in winter, washed and cut into short pieces.

It finds mention in almost all classical compendia of Indian medicine, particularly in the context of rejuvenation therapy. The plant is best known for its tonic, antistress and vigour- and vitality-enhancing properties. The root of the plant is used as such in powder form or in combination with other medicinal plants in various kinds of formulations mentioned in official formularies and pharmacopoeia of India.
