Did You Know?

Narasimha Rasayanam Benefits

The wide-ranging benefits of Narasimha Rasayanam include:

Poor Digestive System

Narasimha Rasayanam packed with herbs like Terminalia chebula and decoctions like Triphala holds the ability to not only improve the functioning of the digestive system but also to cure it of various disorders like constipation. However, for people with a very weak digestive system, this medicine might not be the ultimate remedy due to its high-fat content.

Gaining Weight

Narasimha Rasayanam improves metabolism and digestive system functioning. This, in turn, improves the nutrition intake of the body which might otherwise get excreted unused. Improved metabolism also indicates an improved appetite which is necessary in case someone aspires to gain weight. A small dosage is recommended for people with a weak digestive system.

For Physical Strength And To Boost Immunity

Often known as ‘Man-lion tonic,’ Narasimha Rasayanam is majorly used to decrease debility. It works as a rejuvenative agent and hence also limits ageing as it reduces weakness of muscles and bones. It creates a stable and firm body (sthira anga). This herbal ghrita is often used as a health tonic due to its ability to provide all-round benefits to the body.

The immunomodulatory function of the drug ensures the body is able to fight infections and flu efficiently.

Issues Related To Bones

Narsimha Rasayana is effective in balancing the Vata dosha which mostly causes disorders related to joints. It is also known to be an effective remedy when suffering from osteoarthritis. Osteoarthritis is a painful disorder caused due to reduction of synovial fluid in the joints which is responsible for smooth sliding and gliding of joints. Narasimha Rasayana stimulates the production of synovial fluid and helps in reducing joint pain.

Sexual Wellbeing

Narasimha Rasayanam as mentioned in Ashtanagahridayam is helpful in improving sexual wellbeing. Loss of libido can be cured by its regular intake as it is a natural aphrodisiac. It is also known to be beneficial in case one is suffering from erectile dysfunction.

Hair Growth and Baldness

People suffer from hair issues like premature balding due to different issues like genetic factors, increasing stress and pollution. Narasimha Rasayanam is there to the rescue in all such cases as one of the well-known benefits of it is its wondrous effects on hair growth. It has the ability to slow the greying of hair, increase hair growth and even to rejuvenate the hair. Even in disorders like alopecia, the doctor might suggest this medicine as a remedy. Taking the rasayanam orally in required dosage and regularly massaging the scalp with medicinal oils like Nilibhrigandi oil can help produce desired results.

Side Effects And Precautions

Although no major side effects of Narasimha Rasayanam are known, the following issues can occur if a person is unable to digest it properly:

  • Bloating
  • Dizziness
  • Diarrhoea
  • Nausea and vomiting
  • Palpitation

Being a ghrita (a medicine with butter as a base), Narasimha Rasayanam must not be consumed if suffering from the following conditions:
