9.Hibiscus
This flower, which originally came from ancient Egypt, produces a red brew full of antioxidants. Some small studies have found that it can lower blood pressure. Could it also cut cholesterol? It shows promise, but researchers want to investigate it more. As long you as you drink it in moderation, it’s considered safe.
10.Echinacea
Coneflower (its common name) is known as a cold remedy, but science doesn’t really back that up. It does seem to boost the immune system, and researchers are studying it as a treatment for the flu. If you’re pregnant or have allergies or asthma, it’s best to steer clear. It can also affect how well certain drugs work.
