My mothet has a constipation problem ever since she had an heart attack 1.5 years back. She tried many treatments allopathic homeopathic and ayurvedic like pilex, zandu nityam, Triphala with no or negligible result. She recently on the advice of a doctor started taking 3 to 4 spoons of milk and 3 to 4 drops of almond oil in it daily before sleep in night. Yes the results  were remarkable. Daily morning clear motion. She took it for 6 consecutive days. My question is this safe for prolonged use? Are there any side effects of it.?will it adverse effect  any. Second will this treatment work with permanent cure and long term cure
