Also known as golden root or Arctic root, rhodiola (Rhodiola rosea) is an herb long used in traditional medicine in Russia and some European countries. Rhodiola is considered an adaptogen, a class of herbs said to help the body build resistance to stress.
Why Do People Use Rhodiola?
In herbal medicine, rhodiola is typically used in treatment of these health problems:
Benefits of Rhodiola
Although the health effects of rhodiola have yet to be extensively studied, research suggests that the herb may be useful in treatment of the following:
1) Stress-related fatigue
Regular intake of rhodiola may help fight fatigue and, in turn, boost mental performance in people struggling with stress-induced burnout, according to a study published in 2009. Study results also showed that the 30 participants taking rhodiola supplements for 28 days had a greater improvement in concentration than those who took a placebo pill for the same amount of time.
In a 2007 study, researchers had 89 adults with mild to moderate depression take 340 mg of rhodiola extract, 680 mg of rhodiola extract, or two placebo tablets every day for six weeks. Among those taking either dose of rhodiola, significant improvements in overall depression, insomnia, and emotional instability (but not self-esteem) were gained over the course of the treatment period. Study members taking the placebo tablets showed no such improvements. What's more, no serious side effects were reported by any participants.
Preliminary research suggests that rhodiola extract daily may help prevent arrhythmias (disorders of the regular rhythmic beating of the heart). However, rhodiola's heart-protecting properties need to be further studied before the herb can be recommended as a treatment for arrhythmia (a potentially serious problem that can lead to heart disease, stroke, or sudden cardiac death in some cases).
How to Use Rhodiola
Available in capsule, liquid, and tea form, rhodiola can be found in many health food stores. The extract is often sold in formulas that contain other adaptogenic herbs.
Although rhodiola is generally considered safe, it may trigger adverse effects like irritability and insomnia. If you're considering using rhodiola in treatment of a medical condition, make sure to consult a physician before you begin taking the herb.
