1.Rooibos
It comes from a plant native to South Africa, and the drink there is called redbush tea. It’s caffeine-free and is often touted for its antioxidants. Some researchers believe, based on studies done on animals, that this herb may boost the immune system and help prevent cancer. They are also looking into whether it can benefit your heart and fight diabetes. Check with your doctor before you use it if you have a hormone-sensitive cancer or you’re on chemotherapy.
2.Chamomile
For centuries, people have used this flowering plant to ease upset stomach, gas, diarrhea, insomnia, and anxiety. Some research suggests that it may help relieve generalized anxiety disorder, but there’s not much evidence to back other claims. You shouldn’t drink it if you’re allergic to ragweed. It’s also known to interact with blood thinners, such as warfarin, as well as some other drugs.
