Herbs Causing Anxiety: What You Need to Know

When you reach for herbs causing anxiety, natural plant-based remedies that can unintentionally trigger or worsen anxiety symptoms, you’re not always getting calm—you might be getting a jolt. Many people turn to herbal supplements thinking they’re safe, gentle, and free of side effects. But some of these so-called natural solutions can mess with your nervous system just like prescription drugs—sometimes even more unpredictably. Licorice root, a common ingredient in teas and digestive aids can raise cortisol and blood pressure, making your heart race and your mind spin. Ephedra, once popular in weight-loss formulas and now banned in many places but still found in unregulated products is a stimulant that mimics adrenaline, and it’s known to cause panic attacks in sensitive people. Even green tea extract, often seen as a healthy antioxidant boost, can trigger anxiety if taken in concentrated pill form because of its high caffeine content.

It’s not just about stimulants. Some herbs interact with brain chemicals in ways you wouldn’t expect. Kava, used for relaxation but linked to liver damage and paradoxical anxiety spikes, can make you feel wired instead of calm after a few days. St. John’s Wort, famously promoted for mild depression, can interfere with serotonin and cause agitation, especially if you’re already on antidepressants. And then there’s ginseng, a popular adaptogen that can overstimulate instead of balance—especially if taken late in the day. These aren’t rare cases. People report jitteriness, racing thoughts, and sleepless nights after starting herbal regimens they thought were harmless. The problem? Most herbal products aren’t tested for mental health side effects the way pharmaceuticals are. Labels don’t warn you. Doctors don’t always ask about them. And you might not connect the dots until your anxiety is already out of control.

If you’ve been using herbal supplements for stress, sleep, or energy and suddenly feel more on edge than ever, it’s worth pausing. Track what you’ve added to your routine in the last 30 days. Cut one out at a time. See if your symptoms improve. You don’t need to quit all herbs—many are safe and helpful. But you do need to know which ones could be working against you. Below, you’ll find real stories and expert insights from people who’ve dealt with this exact issue. Some found relief by switching to safer alternatives. Others discovered their anxiety wasn’t just in their head—it was in their supplement bottle.
