Ginkgo biloba, often touted as a memory enhancer, faces skepticism from numerous studies. However, the *American Journal of Medicine* highlights its effectiveness in treating intermittent claudication, a painful leg circulation issue. Research indicates that ginkgo modestly improves the distance patients can walk pain-free, mirroring the benefits of conventional medication. Yet, neither approach surpasses the advantages of regular exercise.
Ginkgo biloba boasts a wealth of antioxidants and active compounds that boost circulation. According to Varro E. Tyler, Ph.D., a pharmacognosy expert, ginkgo may also reduce blood clot formation and fortify blood vessels. While generally safe, ginkgo can elevate bleeding risk when combined with aspirin, warfarin, or other blood-thinning medications.
Kava is favored for managing short-term stress, like looming deadlines, and easing anxiety related to anticipated events or anxiety-induced insomnia.
Research supports these uses. A University of Exeter meta-analysis confirmed kava’s effectiveness in reducing anxiety. Kava’s active compounds may relax muscles by influencing brain receptors and suppressing stress hormones. While not addictive, long-term kava use isn’t recommended by herbal experts. High doses can cause drowsiness, posing risks while driving or operating machinery. Avoid combining kava with alcohol or sedatives.
Saw palmetto berry extract is a popular treatment for men’s urinary problems stemming from benign prostatic hyperplasia (BPH), or prostate enlargement. This non-cancerous condition involves inflamed prostate tissue that develops with age, affecting roughly half of men over 50 with symptoms like frequent urination.
A *Journal of the American Medical Association* (JAMA) study involving nearly 3,000 patients revealed that saw palmetto can improve urine flow and decrease nighttime urination. Some studies suggest it rivals the drug Proscar (finasteride), but without side effects like decreased libido or impotence. Saw palmetto doesn’t significantly shrink the prostate and doesn’t affect hormone levels, explaining the absence of Proscar’s typical side effects. Before using saw palmetto for BPH, consult a doctor to rule out prostate cancer.
