Popularly known as winter cherry, Ashwagandha (Withania somnifera) is a widely used herb due to its numerous medicinal and restorative properties.

Ashwagandha protects cells from oxidative damage and stress-related diseases such as depression, high blood pressure and cardiovascular conditions. Being an adaptogen, it improves a person’s ability to cope with stress.[1,2,3,4,5,6] It also improves lower limb muscular strength and neuro-muscular co-ordination.[7]

Besides this, ashwagandha’s antimicrobial properties and antibacterial activities protect against potentially dangerous bacteria, including Salmonella—a bacteria that causes food poisoning.[8]

Ashwagandha For Underactive Thyroid (Hypothyroidism)
Ashwagandha improves the functioning of the thyroid gland by increasing the secretion of T4 and T3 hormones in the blood, thus reducing lipid peroxidation—the process by which free radicals remove electrons from lipids (fats) in the cell, causing cell damage.[9,10]

Ashwagandha scavenges free radicals to prevent damage to vital organs such as the thyroid gland, heart, liver, skin, and almost all cells of the body.[11] This relieves the body from fatigue, depression, constipation and muscle cramps—all of which are symptoms of hypothyroidism.

How To Take It

  • Ashwagandha can be taken as a fluid extract or supplement. Talk to a naturopath to determine the correct dosage for you.
  • To make ashwagandha tea, pour boiling water on five ashwagandha leaves and let them infuse for 10 minutes. Drink one cup of this decoction in the morning and one in the evening for better results. However, do not have more than two cups per day as a high dose of ashwagandha can lead to thyrotoxicosis (excess of thyroid hormone in the body).[12]
