Hi my father has skin allergy, mouth ulcer and gas problems for 15 years my first question is whether virenchan is suitable for a man aged 60 yrs. my father wants to undergo virechan therapy to remove his skin allergy problems. he is very weak. his daily diet is restricted to 2-3 chapatis, a bowl of porridge, banana and chiku. he has piles problem. if he undergoes virenchan therapy, how many days will it take and are there any side effects.? whether virenchan therapy is different in different Ayurveda hospitals? he had been given iron injections in august 2017 to increase haemoglobin. pls provide some inputs as to whether he should undergo.
