Some medications for anxiety relief can have uncomfortable side effects. So, at times, people with anxiety consider herbal remedies as alternatives. Examples include chamomile, valerian, and more.
Talking with a doctor before reducing or stopping prescription medication or starting an herbal supplement is important. Many medications derived from ingredients in herbs can be potent, cause side effects, and interact with other medications.
Here, we describe nine herbs and supplements that could help alleviate anxiety.
Different herbs can affect the body in different ways.
For example, some ashwagandha can reduce levels of the stress hormone cortisol in the blood. Long-term exposure to high circulating cortisol levels can increase a person’s risk of developing anxiety.

Ashwagandha or Withania somnifera is among a group of herbs called “adaptogens.”
Adaptogens affect systems and hormones that regulate a person’s stress response. Ashwagandha has a long history of use in traditional Indian, or Ayurvedic, medication.
The 8-week study involved 58 participants with perceived stress. Each participant randomly received one of three treatments: Ashwagandha extract at doses of either 250 milligrams (mg) per day, 600 mg per day, or a placebo.
The participants who took ashwagandha showed less cortisol than those in the placebo group. They also experienced improved sleep quality.
Participants who took 600 mg of ashwagandha reported significantly reduced stress levels. However, participants who took the lower dose of ashwagandha did not report a stress reduction.
People can take ashwagandha as a tablet or in liquid tincture form.
Chamomile is a flowering herb similar in appearance to a daisy. People can use two types of chamomile medicinally: Roman chamomile and German chamomile.
Some people use chamomile in the following forms to help relieve stress and anxiety:
- skin cream
All 93 participants received 1,500 mg of chamomile daily for 12 weeks. Some continued taking chamomile for 26 weeks, while the remainder switched to a placebo.
Researchers observed that those participants who continued taking chamomile were no less likely to experience a relapse of GAD symptoms than those switching to placebo. However, when relapse did occur, the symptoms were less severe.

It is important for anyone taking any type of medication to check with their doctor before consuming chamomile teas or supplements.

They must also be aware that herbal remedies can take longer to start working than prescription medications.
If a person needs more advice about an herbal product, they can consult a qualified herbalist about brand, strength, and quantity.
