People try flaxseed oil for many different conditions, including rheumatoid arthritis and high cholesterol. It is also tried for treating osteoarthritis, anxiety, benign prostatic hyperplasia (BPH), vaginal infections, dry eyes, “hardening of the arteries” (atherosclerosis), high blood pressure, heart disease & diabetes. Several studies indicate that flaxseed oil, as well as ground flaxseeds, can lower cholesterol, thereby significantly reducing the risk of heart disease. Taking flaxseed oil may also protect against angina (chest pain) and high blood pressure. In addition, a five-year study done recently at Boston's Simmons College found that flaxseed oil may be useful in preventing a second heart attack.
