Lots of people swear by herbal supplements. Last year, Americans spent $22.3 billion on herbs like echinacea, ginkgo biloba, Saint-John's-wort and goldenseal.
But a new study, published in the Mayo Clinic Proceedings, indicates many people also have no idea whether these touted remedies are effective. Worse, they're largely ignorant of the potential health risks.
And yet, more than two-thirds of supplements have never been clinically proven to be effective for the specific conditions they're advertised to ease or cure.
Supplements that offer no benefit but also do no harm are merely a waste of money. More worrisome, said Dr. Aditya Bardia of the Mayo Clinic, are supplements that can actually produce adverse effects, from nausea and vomiting to liver and kidney dysfunction.
Generally speaking, herbal supplements aren't regulated like traditional drugs. Randomized, controlled clinical trials aren't mandated before they can be sold. The researchers advise patients to always inform their doctors (and doctors should always ask) about herbal supplement use, because interaction with therapeutic drugs can result in worse health and, on occasion, death.

FOOT PROBLEMS IN OBESE KIDS
Add foot problems to the growing list of ailments for obese children. The American College of Foot and Ankle Surgeons says more overweight children have foot and ankle pain. The vicious circle of foot pain and obesity may hinder some children from progressing. Researchers say childhood obesity changes foot structure and results in instability when walking. Being overweight flattens the foot, causing heel pain. It also can increase the risk of stress fractures in the heel bones.
CAFFEINE AND WORKOUTS
While caffeine may offer a boost in long-distance activities, when it comes to short-term, high-intensity workouts, it may hurt performance, an International Journal of Sport Nutrition and Exercise Metabolism study says. Exercisers were given either caffeine (equivalent of three cups of coffee) or a placebo and evaluated on 60-second maximum-effort cycling tests. The caffeine group had higher blood levels of lactic acid produced by overworked muscles and took longer to reach peak power.
