Saw palmetto is a popular "natural" choice for urinary symptoms from an enlarged prostate, but high-quality studies show little or no real benefit. Men are urged to talk with a doctor first, both to rule out serious causes and avoid misplaced hope.

Vaginal probiotics contain live microorganisms and come in oral and suppository forms. Some ads claim these products can prevent or treat infections. But the vagina regulates its own bacterial mix, so vaginal probiotics aren't necessary.

An endometrial biopsy is the only way to rule out endometrial (or uterine) cancer. Any vaginal bleeding a year or more after a woman's final period raises the possibility of uterine cancer. The biopsy involves using a suction tube to gather cells from the uterine lining.

Elderberry syrup or tea may help reduce the duration and severity of cold and flu symptoms, but the evidence for these benefits is uncertain. Claims that elderberry products can prevent viral infections or boost immunity are unproven.

Daily nasal irrigation (nasal rinses) may reduce symptom severity and the duration of a cold. It can also relieve the congestion caused by sinus infections and allergies. By means of a squeeze bottle, neti pot, or battery-powered system, saline is inserted into one nostril and flows out the other.

After menopause, women develop heart failure at rates similar to men. But women tend to develop heart failure with preserved ejection fraction, which leads to more frequent hospitalizations. Women also have different risk factors for heart failure than men.

Fitness ideals for women have evolved to prioritize a strong body rather than a slim figure. Strength training counteracts age-related muscle loss and offers a wide variety of additional health benefits. Cardio boosts heart health, but can't substitute for strength training.

People's lips may appear thinner with age due to several factors, including lower production of collagen and elastin, proteins that provide plumpness to skin. Genes also play a role, as do habits such as smoking and excessive sun exposure.

A 2025 study suggests that adjusting the intensity of breast cancer screening based on individual risk factors is as effective as annual mammograms.

About half of Americans have herpes simplex virus type 1, which causes cold sores that can recur periodically. The virus can't be eliminated, but topical and oral treatments can help. In addition, people can avoid cold sore triggers such as stress or fatigue.
