Hi,
I suggest you please before starting any kind of medicine, try meditation, relaxation, Yoga and some techniques which help you to back to the moral life. As I know Crona unfortunately can effects on heart and blood pressure and also hypertension. So you don't need any medicine to reduce them, you need some activities to bring you back to normal...
Please don't rely on any medicine and start Yoga and meditation. They are like magical treatment...
Do take care!
Next Steps
