A staple of ayurvedic medicine, ashwagandha restores energy, fights disease and promotes healthy sleep. It’s been used as a medicinal herb to treat the body and mind for over 3,000 years. Recent studies indicate that one of the benefits is that it can improve memory. But can it treat Alzheimer’s?

What is Ashwagandha?

Native to dry regions of India, Northern Africa and the Middle East, ashwagandha has been around for millennia. It’s a relative of the tomato. Ayurvedic medicine looks to the plant’s leaves for therapeutic benefits, but Western cultures rely on its roots to make herbal remedies.

What Diseases Can Ashwagandha Fight?

According to the Chopra Center, studies have shown that ashwagandha provides a range of health benefits, from lowering cholesterol and stabilizing blood sugar to reducing inflammation and anxiety. In turn, these benefits help fight a number of diseases, including:

  • asthma
  • arthritis
  • chronic fatigue
  • anemia
  • infertility
  • depression
  • ulcers
  • high blood pressure
  • depression
  • some cancers

Ashwagandha also has shown to improve learning and memory. Ayurvedic practitioners recommend it as a brain booster and a remedy for forgetfulness.

How Can Ashwagandha Fight Alzheimer’s?

Studies

Researchers at Newcastle University have found that it inhibits the formation of beta-amyloid plaques. These plaques, considered toxic to brain cells, accumulate in the brains of people with neurodegenerative diseases, such as Alzheimer’s. Because the studies were conducted in test tubes, however, researchers emphasize that more testing is needed.

At the National Brain Research Center (NBRC), scientists tested the herb on mice with Alzheimer’s. After 20 days of treatment cognitive performance of the mice improved significantly. At the end of 30 days, their brain function had returned to normal and the amyloid plaques that had been present in the mice’s brains were reduced.

Moreover, the study showed that rather than altering brain chemistry directly, ashwagandha boosts a protein in the liver. This protein clears amyloid from the brain.
