Cold and Cough: Cold and cough are generally caused by Kapha imbalance in the body, which leads to accumulation of excess mucus in the respiratory tract. Kantakari with its Kapha balancing properties helps in thinning the mucus as well as lowering its production in the body, thus treating the symptoms of cold and cough.

It also aids in diluting the bronchioles, thus decreasing the swelling of the respiratory tract and the production of mucus as well. Other than asthma, Kanthakari works to cure chronic bronchitis and pneumonia and prevent respiratory allergies, sinusitis, etc.

The Pachan (digestive) and Deepan (appetizer) properties of Kanthakari improve the digestive fire in the body, thus treating the problem of indigestion.

It also prevents excess acid production in the body. It gives quick relief in problems like acid reflux, heartburn, flatulence, stomach pain, constipation, etc.

Hair Loss: Vatta dosha is one of the main reasons for hair loss, which can also cause dryness of the scalp. Kantakari helps in maintaining Vatta balance in the body, and thus controlling the issue of hair loss and even dandruff. Regular application of Kantakari juice on the scalp not only helps in preventing hair loss but also in boosting hair growth.

Osteoarthritis: The Vatta-balancing property and Ushna potency of Kantakari help in curing osteoarthritis. Joint pain and arthritis are caused due to imbalance of Vatta in the bones and joints, where Vatta resides. Application of the paste of Kantakari on the affected areas helps in reducing the pain and other symptoms of arthritis.

Liver Disorder: The hepataprotective and antioxidant properties of Kantakari protect the liver from the damage caused by free radicals. The herb has the ability to regenerate new cells and improve the metabolism of the liver, ensuring its proper functioning.
