My kid is 6 years old and 22 kg in weight he had a kasai procedure at the time of birth. Now he often lands up with bacterial infection during the change of season from summers to winters leading to cholangitis. Allopathy doesn't have any preventive treatment as per doctors to prevent it. Is there anything in ayurvedic or homeopathic to boost his immunity so that he can fight with bacterial infection. And any thing to take care of liver health also.
