It is very difficult when prescriptions make us feel worse, and there comes a time when we will seek any other choice.
@pkbluff1 There are natural blood thinners around, however if you have a condition like afib or blood clots, any switch should be made with EXTREME caution.
Supplements are unregulated, so you cannot always be certain of the dosage you are getting from them. Supplements act differently from prescription blood thinners, so you must be sure you bridge to the effective dosage. Also, make sure your doctor or a registered pharmacist checks any and all interactions between your other meds and the supplements. Finally, if you chooee a holistic practitioner, be sure they are well trained in anatomy, physiology, disease and treatment. Too often, people who advertise, and who proclaim themselves experts have very limited training, and are in fact simply promoters.

Also, the internet would not be my choice of a diagnostician or prescribed, especially for something as life threatening as stroke or heart disease.
