What is Valerian Root?
Valerian root is an herbal remedy derived from the Valeriana officinalis plant, which is native to Europe and Asia. It has been used for centuries to treat a variety of ailments, most notably for its calming and sedative effects. Today, valerian root is widely available in various forms, including capsules, teas, and extracts.
How It Works
Valerian root works by increasing the levels of gamma-aminobutyric acid (GABA) in the brain. GABA is a neurotransmitter that promotes relaxation and reduces anxiety.
Some of the active ingredients in valerian root function similarly to benzodiazepines, which are commonly prescribed for anxiety and sleep disorders. This makes valerian root a natural alternative for those looking to manage these conditions without pharmaceuticals.
Benefits of Valerian Root
- Sleep Aid: Valerian root is widely recognized for its sedative properties, making it a popular natural remedy for insomnia and sleep disturbances. Some studies indicate that it may help reduce the time it takes to fall asleep and improve overall sleep quality.
- Anxiety Reduction: Valerian root may also help overcome anxiety symptoms. Preliminary studies suggest it has anxiolytic effects—relieving stress and anxiety without the addictive properties associated with some prescription medications.
- Menopausal Symptom Relief: Research indicates that valerian root may help reduce the frequency and severity of hot flashes in menopausal women.
- Support for Other Conditions: Valerian root has been explored for its effects on various other conditions, including:
- Obsessive-Compulsive Disorder (OCD): Some studies suggest it may reduce compulsive behaviors in individuals with OCD.
- Menstrual Symptoms: Valerian root may alleviate symptoms associated with premenstrual syndrome (PMS) and painful menstruation.
- Restless Legs Syndrome: It has been shown to improve symptoms in individuals suffering from this condition.
- Obsessive-Compulsive Disorder (OCD): Some studies suggest it may reduce compulsive behaviors in individuals with OCD.
Side Effects of Valerian Root
- Dizziness and Drowsiness: Users may experience dizziness or excessive drowsiness the day after taking valerian root.
- Headaches: Some individuals report an increase in headaches after using valerian root.
- Stomach Upset: Gastrointestinal issues such as an upset stomach, diarrhea, or increased bowel activity may occur. This laxative effect has been noted in some studies, with a higher incidence of diarrhea among those taking valerian compared to placebo groups.
- Mental Dullness: Users may experience feelings of mental fogginess or sluggishness, especially at higher doses.
- Vivid Dreams: Some people report experiencing more vivid or unusual dreams while taking valerian root.
- Dry Mouth: A dry mouth is another side effect that some users have noted, although this effect has not been studied extensively.

Valerian Root & Weight Loss
Valerian Root and Weight Management
Research suggests that poor sleep can lead to weight gain due to increased cortisol levels, which can drive cravings for unhealthy foods. Valerian root is thought to help improve sleep quality, which in turn may aid in weight loss efforts.
By reducing stress and improving sleep, valerian may help control cravings and support healthier eating habits. Some studies indicate that valerian root can increase levels of gamma-aminobutyric acid (GABA) in the brain, which promotes relaxation and may reduce the urge to eat in response to stress.
Anti-Obesity Effects in Animal Studies
A study investigated the anti-obesity effects of valerian root extracts in mice. The results showed that valerian root extract suppressed the formation of fat cells and reduced body weight and fat accumulation when the mice were fed a high-fat diet. The extract also influenced the expression of genes related to fat storage and metabolism, suggesting that valerian root could be a useful ingredient in preventing obesity.
Valerian Root & Blood Sugar Management
Valerian Root and Blood Sugar Regulation
A study investigated the effects of valerian root on blood sugar levels in diabetic humans. The study found that neither bilberry fruit nor valerian root alone achieved the lowering and regulation of blood sugar levels. However, the combination of the two, taken 30-45 minutes after each meal, was effective in reducing and regulating blood sugar levels in diabetic subjects who were also maintaining a diabetic diet.
Valerian Root & Hormone Balance

Stress and Hormonal Balance
Valerian root is known for its calming effects and can be used to manage stress levels. High stress can increase cortisol levels and disrupt the body’s hormonal balance. By reducing anxiety and promoting relaxation, valerian root may help stabilize hormone levels in the body.
Phytoestrogenic Properties
Valerian root contains phytoestrogens, which are plant compounds that can mimic estrogen in the body. These compounds may play a role in balancing hormones, particularly in women experiencing menopause. By acting similarly to estrogen, valerian root may help alleviate hormonal fluctuations and associated symptoms.
Valerian Root & Menopause Management
Effects of Valerian Root on Hot Flashes
A clinical trial studied the impact of valerian root on hot flashes in menopausal women. In this study, 68 women experiencing hot flashes were divided into two groups: one received valerian root capsules (255 mg, three times a day) for eight weeks, while the other group received a placebo.
The results showed that women taking valerian experienced a significant reduction in both the severity and frequency of hot flashes compared to the placebo group. This suggests that valerian root could be an effective treatment for managing hot flashes in menopausal women, especially for those hesitant to use hormone therapy due to associated risks or concerns.
Menopausal Anxiety and Sleep Issues
Another study explored how valerian root could help with anxiety and sleep disturbances often experienced during menopause. The study found that valerian improved sleep quality and reduced anxiety symptoms in menopausal women. By addressing these issues, valerian may indirectly help manage other menopause-related symptoms such as better sleep and reduced anxiety.
