Herbs for Mild Depression

Herbs can help to adjust brain chemistry in a healthy, non-addictive and holistic way, according to Kathi Keville in the book "Herbs for Chronic Fatigue." Unlike chemical medications, herbs won't impair attention, concentration or reaction time. Several herbs can help in treating mild depression, although there is no scientific evidence to illustrate their efficacy. You should always consult your physician prior to taking herbal supplements.

St. John's Wort

St. John's Wort contains several components, many recognized as having pharmacological properties, according to C.M. Hawken in the book "Natural Treatments for Depression." These compounds include flavonols, flavanones, carotenoids, xanthones, dianthrones, carboxylic acids, sequiterpenes and monoterpenes, Hawken says. Hypericin is the most notable compound present in St. John's Wort and is thought to be the agent most responsible for the herb's antidepressant abilities. It works by increasing blood flow to stressed tissue resulting in a tranquil mind state. Hawken recommends a dosing of 200 to 1,000 mg of extract per day.

Siberian Gingseng

Siberian gingseng is also known as the "stress-busting" herb in that it helps to treat mild depression and associated psychological ailments, according to Gabriel Cousens and Mark Mayell in the book "Depression-Free Life." Similar to other ginseng herbs, the Siberian form is also an adaptogen, meaning it strengthens, normalizes and regulates bodily systems, Cousens and Mayell say. More than three-dozen compounds in this herb affect both the mind and body, with glycosides known eleutherosides being responsible for the psychological benefits.

Licorice

According to James Duke in his book "The Green Pharmacy," licorice is at the forefront of antidepressant herbs due to its plenitude of compounds that help to fight mild depression. At least eight constitutents in licorice are monamine oxidase inhibitors, which act to block depression. Duke recommends adding licorice extract to herbal teas up to three cups per day.
