Walk into a supplement store, and you're bound to see dozens of products with nature-inspired labels boasting ingredients called "botanicals."

But what are botanicals, really? Simply put, these substances consist of different parts of a plant, including the leaf, root, stem, and flower, are Mother Nature's pharmacy. They've been shown to help with everything from stomach issues to headaches and period cramps, plus they support the immune system and help fight stress.

"Bo­tanicals contain hundreds of unique compounds that work via multiple pathways in the body," says Tieraona Low Dog, M.D., a co-author of National Geographic Guide to Medicinal Herbs (Buy It, $22, amazon.com). Many botanicals are also adaptogens, and they adapt to the body's changing, stressful conditions and give our natural stress-management mechanisms an assist, says Robin Foroutan, R.D.N., an integrative medicine dietitian in Garden City, New York.

To address a condition like one of those mentioned above, experts say it makes sense to look to natural remedies, which are mild and usually don't have side effects. (For problems that need more powerful, targeted treatment, a drug may be called for; consult with your doctor.) Here are five science-backed botanicals to consider.

How to Use Botanicals Safely

While botanicals can be very safe, many interact with drugs, particularly if the plant is targeting the same condition as the drug, says Ginger Hultin, R.D.N., a nutritionist in Seattle who specializes in integrative health. Always check with your health care provider before you take a supplement. (More here: How Dietary Supplements Can Interact with Your Prescription Drugs)

Because botanicals aren't regulated by the FDA, they vary widely in quality. When buying them, look for third-party certification, such as NSF International or USP, or check ConsumerLab.com, which tests supplements. Experts recommend these brands: Gaia Herbs, Herb Pharm, Mountain Rose Herbs, and Traditional Medicinals.
