Ashwagandha is one of the powerful herbs of Ayurveda. It is used as a remedy in Ayurveda for a wide variety of diseases like anxiety, depression, insomnia, weight gain, weight loss, etc. It helps enhance immunity, muscle strength, bodybuilding, and sexual stimulation and works as an antioxidant.  

Botanical name:  Withania somnifera 
Family:  Solanaceae

Medicinal qualities of Ashwagandha

Ayurveda explains the pharmacology of the herbs in terms of taste and quality. As per ancient Ayurvedic texts, Ashwagandha has the below-mentioned qualities:
Taste: pungent, spicy, bitter and slightly astringent  
Qualities: oiliness, unctuousness, lightness (easy to digest) 
Taste conversion after digestion: Undergoes pungent taste conversion after digestion. 
Potency: Hot  
Effect on Tridosha: Balances Tridosha, especially Kapha and Vata. 
Ashwagandha being hot, nourishing, and unctuous, helps to counter the cold and dry qualities of Vata Dosha. 
It has spicy, bitter, and light qualities, that are opposite to Kapha Dosha.  
Because of its hotness and spicy taste, it improves digestion strength and also promotes Pitta Dosha.  

Part of Ashwagandha used

• The root is the main used part. 
• The leaves are often used in weight loss therapy. 
• It’s Kshara – An Alkali: The whole plant of Ashwagandha is burnt in the open air, ash is mixed with water thoroughly and left undisturbed for a couple of hours. The supernatant water is decanted out and the precipitated power is collected, heated, dried, and powdered. This Alkali is used for the purpose of weight loss.  

 Dosage of Ashwagandha: 

• Ashwagandha Powder
  3 grams once or twice a day, given with co-drinks such as honey, milk, water, yogurt, honey, and ghee.  
  It is processed with milk and water to prepare Ashwagandha Ksheera – a milk remedy that is given to improve strength and immunity in children. 
  Ashwagandha Capsule or tablet
  250 – 500 mg, once or twice a day, based on doctor’s advice. 

Is Ashwagandha consumed before or after food? 

When Ashwagandha powder, tablet or capsule is administered, some people feel a burning sensation if taken before food or on an empty stomach. Hence, it is best to take it 30 minutes after food. 

Ashwagandha milk remedy or Ashwagandha with ghee can be administered before food as well, based on your doctor’s advice. 

What is Ashtavarga and its Legal Substitute

There is a very famous group of 8 herbs, called Ashtavarga, known to carry very high rejuvenation and anti-aging qualities. But these herbs grow only in certain parts of Himalayas and are found very rarely. So, centuries ago, ancient Ayurvedic masters explained substitutes for these 8 herbs.  
Among them, these are the two herbs that are legally substituted with Ashwagandha due to the similarity in their qualities. This clearly proves the anti-aging prowess of Ashwagandha.

1. Kakoli-Roscoea purpurea
2. Kshirakakoli-Lilium polyphyllum – White Himalaya Lily

Ashwagandha’s (Withania Somnifera) Side effects

Ashwagandha and Hypothyroidism

A double-blind, randomized, placebo-controlled clinical trial in Ashwagandha has proven that treatment with Ashwagandha may be beneficial for normalizing thyroid indices in subclinical hypothyroid patients. 

Ashwagandha is useful in many of the symptoms of hypothyroidism such as – 

1. Fatigue: Ashwagandha boosts energy 
2. Mood and memory changes: Ashwagandha is useful to improve memory and to relieve depression 
3. Sore muscles and joints: Ashwagandha improves muscle and joint strength 
4. High cholesterol: Being a very good antioxidant, Ashwagandha helps to reduce cholesterol. 

Considering these benefits, it is very clear that Ashwagandha is very useful for the treatment of hypothyroidism. 

Increased hotness, gastritis

If used alone, for example, consuming only an Ashwagandha capsule with water tends to worsen gastritis in people with sensitive stomachs. It also causes constipation in a few. 

Because of its innate hot nature, people with Pitta dominance, feel increased hotness with the Ashwagandha capsule. 

But if it is taken along with milk or ghee, usually this side effect is very much nullified. 

Sedative effect: In a very high dose, it may have a mild sedative effect. Its sleep promotion effect can be more attributed to its anti-anxiety and anti-depression properties than to its sedative effect. 
Some people also observe constipation, loose stools, abdominal cramps, and drowsiness. 

It can be used safely for children and lactating mothers, under medical supervision. 

It is best to avoid this during pregnancy. 

Who should not take Ashwagandha? 

Being a Rasayana herb (anti-aging), as such there are no definitive contra-indications. However, the following symptoms should be noticed when you consume Ashwagandha. 

• Excess body heat – Give it 2–3 days to settle, if not, then stop it.  
• If you take it and then develop severe anxiety or unrest – stop it and consult a doctor. 
• If it makes you drowsy, avoid it in the morning.  
• If it upsets your stomach, you can give it a try for a couple of days to see if it settles down.
• If it causes diarrhea or constipation, you can continue for a couple of days to see if the side effects subside. 
• If it causes irregular heartbeat, stop it and consult your doctor. This is a very rare side effect.  
• If it lowers blood pressure/sugar, probably the dose is higher. Stop it and consult your doctor.
