Hi! I am Erlinda Manahan, 59 years old, has a weight of 42 kgs and is 4 11 in height. I have been diagnosed with hypertension and is taking lossartan potassium 100 mg and ambesyl 20 mg. Now, it s almost a week that I have been bothered by itchy throat and cough. I have tried taking lemon with tea & honey, have tried taking pei pa koa but up to now I can not sleep at night because of that. What can I do?
