I am 70 years old. I have been suffering from acute Smoker's Allergic Bronchitis. It's not COPD nor Asthma. Some 5 months back when I consulted an Ayurvedic Doctor, he prescribed me some medicines, the details of which are hereunder. LAKSHMI VILAS RAS to keep my nervous system and overall health intact.(One tablet one in the morning and one at night) AYUENZYME for the gastric problem and continuous burping.(Two tablets-morning and night) AROGYAVARDHINI BATI to keep my liver function intact. One tablet - Three times a day) SOMCO to check my uncontrollable dry cough. (Two tablets Morning and Night). Can I use these life-long or as long as I can? Is it harmful or do they have side-effects if I use them for years together?
