Herbal Supplements 101: What They Are and What to Know Before Trying One

Herbal supplements — remedies derived from plants — have been used across cultures for centuries, and many are popular again today. But “herbal” and “natural” don’t automatically mean well-studied or risk-free. Here’s what’s worth knowing.

Common herbal supplements people try

Chamomile and valerian are traditionally used for relaxation and sleep. Turmeric is associated with anti-inflammatory properties. Ginger is commonly used for digestion. Ashwagandha is popular for stress support. Research on each varies in strength and quality.

Evidence varies a lot between herbs

Some herbal supplements have a reasonable body of research behind them; others rely mostly on traditional use with limited modern studies. It’s worth looking into the specific evidence for any herb you’re considering, rather than assuming “herbal” means “proven.”

“Natural” doesn’t mean risk-free

Herbal supplements can still interact with medications, affect blood pressure, blood sugar, or blood clotting, and cause side effects — particularly at high doses or combined with other supplements.

Quality and sourcing matter

Herbal products can vary in potency and purity between brands. Look for third-party testing and reputable manufacturers, just as you would with any other supplement.

Talk to a doctor before combining with medication

This is especially important if you’re pregnant, nursing, managing a chronic condition, or taking prescription medication — herbal supplements are not automatically safe to combine with everything.
