5 Herbs for Anxiety – Experience Life
It can be difficult to catch a breath these days. Between our always-on work and media culture, an accelerated pace of life, and timeless challenges like raising kids and providing eldercare, life in the 21st century can be anxiety-provoking. To say the least.
“We live in unacceptably stressful times,” says integrative psychiatrist Henry Emmons, MD, author of The Chemistry of Calm. “People are so uniformly stressed that they are looking for quick relief, often in the form of alcohol or prescription drugs. We need better options.”
Fortunately, we have them — and have had them for some time. “Plants have been used to relieve anxiety for thousands of years because anxiety has always existed,” he explains.
Anxiety originates in the brain’s amygdalae, two almond-sized structures (one in each hemisphere) that modulate the body’s response to stress. Functional-medicine physician and herbalist Aviva Romm, MD, likens their function to a surveillance system: When we perceive danger, the body’s stress response sounds the alarm and releases a torrent of hormones, including adrenaline and cortisol. This prepares the body to fight, flee, or freeze.
The hypervigilance that accompanies this response is key to survival, Romm says. “But when the alarm gets stuck in the on position, hypervigilance turns into anxiety.”
This can take many forms. For some, it feels like a racing heart or a queasy stomach. In others, it creeps in like a fog of overwhelming emotions or a persistent sense of dread.
An estimated 40 million Americans experience these sensations often enough to be diagnosed with an anxiety disorder, such as social anxiety disorder, panic disorder, and generalized anxiety disorder, or GAD, which is the most common.
Best Herb for Acute Anxiety Relief
Kava (Piper methysticum)
The root of a plant native to the South Pacific, kava is perhaps the best-researched herb for anxiety relief. Randomized, double-blind, placebo-controlled studies show that kava significantly reduces anxiety. Most participants found relief when taking between 120 and 240 mg of the herb daily over a period of weeks, but it also works well as an on-the-spot remedy.
“Kava is the best example of an herb that matches the effectiveness of an antianxiety medication but without the side effects,” says Emmons. The herb acts fast, often in just 15 to 20 minutes. This makes it especially useful in acute situations — after a near accident, a heated conversation, or anytime the stress response kicks in.
Best of all, kava relaxes the muscles without sedating the brain. “Muscle tension can exacerbate, enhance, and amplify feelings of anxiety,” says Mazzarella. “But with kava, you literally feel the sensation of coming down.”
How to Use: When anxiety strikes, take a dropperful of kava tincture in a small glass of water. Your lips may tingle a bit.
Safety Note: Kava is a potent herb and has been linked to liver damage. Romm recommends using it primarily as an “emergency remedy” for panic or acute anxiety, like stage fright or a fear of flying.
“It is overwhelmingly safe for occasional use — a few times a month — and even daily use at very low doses,” she says. “For higher doses, taken regularly, I recommend working with a licensed practitioner. There is a remote risk of it affecting the liver.”
Best Herb for Insomnia
Passionflower (Passiflora incarnata)
Passionflower can relieve anxiety-induced insomnia. The herb’s flavonoids and alkaloids interact with GABA to gently muffle the body’s alarm bells. Emmons calls it “a potent and underutilized herb for sleep.” It’s Mazzarella’s favorite remedy for quieting circular thinking: “Most people find it both mentally and physically relaxing.”
In addition to relaxing the mind for sleep, passionflower can help calm anticipatory fear. In a recent study, researchers gave 40 dental-surgery patients 260 mg of passionflower 30 minutes before their procedures. The herb lowered signs of anxiety (measured by blood pressure and heart rate) as effectively as the pharmaceutical sedative midazolam but with fewer side effects.
How to Use: Nighttime waking is the most common sleep complaint that Mazzarella addresses in her clinic. She suggests placing a small cup of water with passionflower tincture on your nightstand. “That way, if you find yourself awake and lost in a worry loop, you’re prepared.”
Best Herb for Chronic Stress
Ashwagandha (Withania somnifera)
This adaptogenic herb helps the body rein in a runaway stress response by addressing chronically high cortisol and adrenaline. Romm calls ashwagandha “a nerve tonic that builds resilience and coping.”
In a review of five randomized controlled clinical trials, researchers noted significant anxiety relief among 400 participants who took daily doses of ashwagandha ranging from 120 to 1,200 mg for six to 16 weeks.
Over time, ashwagandha helps return the body’s stress response to baseline, says Mazzarella. It may especially benefit anxiety sufferers with a history of trauma, who often experience anxious hypervigilance. (For more on ashwagandha and other adaptogenic herbs, see “Ancient Healers: Adaptogens”.)
How to Use: Mazzarella recommends taking ashwagandha for at least three months. “People taking ashwagandha report an almost imperceptible upturn in mood and overall energy,” she says. “They’ll say, ‘I can handle things more easily’ or ‘Life is just better.’”
Best Herb for Restoring Mental Focus
Rhodiola (Rhodiola rosea)
Rhodiola has a history of use in supporting memory and mental focus, especially in northern locales, such as Siberia, where it grows wild. It’s also used to treat immune depletion resulting from overwork, chemotherapy, radiation, and other stressors.
Mazzarella likes Rhodiola for its fast-acting assistance with focus, especially for stressful tasks like studying for an exam or rushing to meet a deadline. It’s ideal for “a big push of cognitive labor,” she says.
Despite Rhodiola’s obvious appeal for people working long hours, research is scarce. But a small 2008 clinical trial at the University of California, Los Angeles, found that people with a generalized anxiety disorder who took 340 mg of Rhodiola extract daily for 10 weeks felt significant improvements — and experienced few side effects.
“Rhodiola is good for supporting and restoring a strained-adrenal system,” says Emmons, “especially if chronic stress has left you with brain fog.”
How to Use: Rhodiola can be mildly stimulating, so it’s best taken in the morning or early afternoon. Tinctures and capsules are both effective.
Best Herb for Mild to Moderate Anxiety
Chamomile (Matricaria recutita)
Chamomile is one of the oldest and most widely studied herbs. An estimated 1 million cups of chamomile tea are consumed worldwide every day. It can also be taken as a tincture.
“Chamomile is one of the safest calming herbs you can try,” says functional-medicine practitioner Mark Menolascino, MD.
Chamomile has many calming constituents, but one of the most potent is apigenin, a flavonoid that influences GABA.
Although chamomile is typically used for mild anxiety, new research hints that it can tackle moderate to severe symptoms too. In a 2016 study published in Phytomedicine, people with generalized anxiety disorder took 500 mg of chamomile three times daily for up to eight weeks. More than half-reported a “clinically meaningful” reduction in symptoms.
How to Use: Chamomile comes in many forms, but herbal tea is the most traditional form used to ease anxiety. Pour hot water over 2 to 3 heaping teaspoons of dried chamomile, steep for five to 10 minutes, then strain. Drink as needed throughout the day.
