Valerian Root: Benefits, Uses, Effects and Safety Explained
A natural approach to calm your mind, ease discomfort, and restore restful nights.
What Is Valerian Root?
Valerian root is a herbal supplement derived from the Valeriana officinalis plant, traditionally used for centuries as a natural remedy for various health concerns including insomnia, anxiety, headaches, and menstrual issues. Originating from Europe and Asia, valerian root has become increasingly popular in the United States, with its usage rising alongside growing interest in alternative and complementary medicine.
- Valerian root comes in forms such as capsules, teas, liquid extracts, and dried powders.
- It is most often consumed for its sedative and calming effects.
- Commonly found in sleep aid products and blends for stress relief.
The plant’s roots, rhizomes, and stolons are used medicinally, containing several active compounds that are believed to impact the nervous system.
Valerian Root: Key Potential Health Benefits
While valerian’s effects have been studied for centuries, scientific research is still in progress to understand its mechanisms and potency. Based on current evidence, valerian root may offer the following potential benefits:
1. Promotes Sleep and May Ease Insomnia
Valerian root is most widely recognized for its use in improving sleep quality and managing insomnia. Modern studies suggest valerian may help some people fall asleep faster, enhance sleep depth, and reduce nighttime awakenings.
- Valerian increases levels of the neurotransmitter GABA (gamma-aminobutyric acid) in the brain, which helps quiet nervous system activity. Increased GABA is associated with relaxation and sleep initiation.
- Some research shows valerian’s sedative effect is mild and may be more noticeable in people experiencing regular sleep difficulties.
| Sleep Impact | Evidence Strength | Typical Dosage |
|---|---|---|
| Falling asleep faster | Moderate | 400–900 mg before bed |
| Improved sleep quality | Moderate | 400–900 mg before bed |
| Reduced nighttime awakenings | Limited | 400–900 mg before bed |
*Note: While studies do show sleep improvements, many have methodological limitations. Results may vary depending on individual biology and response.
2. Reduces Anxiety and Supports Stress Management
Valerian root has a long tradition as an anxiolytic (anti-anxiety) remedy and continues to be explored for its potential to alleviate anxious feelings and stress responses.
- Emerging research suggests valerian can reduce symptoms of anxiety, stress, and some mood disorders, potentially by boosting GABA and affecting serotonin receptors.
- Studies in specific groups (e.g., hemodialysis patients, individuals with OCD) show reductions in anxiety after regular valerian supplementation.
- May help modulate brain activity associated with the perception of stress.
What others are reading
Valerian root should not be used simultaneously with certain prescription medications for anxiety, such as benzodiazepines, barbiturates, or opiates, due to possible interactions.
3. May Support Women’s Health (Menopause and PMS)
Women’s health is another major area where valerian root shows promise:
- Menopausal symptoms: Studies show valerian may reduce the severity and frequency of hot flashes in menopausal and postmenopausal women.
- Premenstrual syndrome (PMS): Valerian may help ease both emotional and physical symptoms of PMS such as cramps, mood swings, irritability, and sleep disruptions.
For those unable to use hormonal therapies to manage menopausal symptoms due to underlying health risks, valerian root may offer a gentler alternative, though more high-quality research is needed.
4. Potential Relief for Restless Legs Syndrome (RLS)
Restless legs syndrome is a neurological condition causing uncomfortable sensations and an irresistible urge to move the legs, often disturbing sleep.
- An 8-week study indicated valerian could reduce RLS symptoms and associated daytime sleepiness with daily supplementation of 800 mg.
- Mechanism may be linked to GABAergic effects and muscle relaxation.
5. Possible Aid for Headaches and Pain
Though not extensively researched in humans, valerian root is used anecdotally to ease headaches, menstrual pain, and general discomfort.
- Animal studies hint valerian could help with chronic and acute pain, particularly when combined with other botanicals.
- Users often report subjective improvement in pain symptoms.
Other Areas of Interest
- May help children with concentration and hyperactivity difficulties when used carefully and combined with other herbs.
- Possible improvements in OCD-related symptoms as suggested by some pilot studies.
- Has antioxidant properties that may contribute to overall brain health.
How Does Valerian Root Work?
The exact mechanisms responsible for valerian’s effects remain under investigation. Researchers have identified several active compounds believed to be responsible:
- Valerenic acid and valerenol: Thought to impact GABA receptors and nervous system relaxation.
- Valepotriates (iridoids): May contribute to sedative and anxiolytic properties.
- Flavonoids, lignans, and essential oils: Antioxidant and anti-inflammatory effects.
- GABA: Present in low levels, supports calming neurotransmission.
Valerian root appears to modulate the way the brain processes signals for relaxation, stress, and sleep through its impacts primarily on GABAergic activity, along with possible actions on serotonin and other chemical pathways.
Valerian Root: Dosage and Forms
Valerian root is available in several supplement types, allowing users to tailor intake to their preferences and needs.
- Capsules/Tablets: Convenient; typically 300–900 mg per serving.
- Dried tea blends: 2–3 grams per cup, steeped 10–15 minutes.
- Liquid extracts/tinctures: Dosage varies; follow package instructions.
- Powdered root: Can be mixed into foods or drinks.
Optimal dosage varies by age, health status, intended purpose, and product. Most studies use 400–900 mg taken 30–120 minutes before bedtime for sleep improvement. Lower doses may be sufficient for mild stress or anxiety.
Possible Side Effects and Safety Considerations
Valerian root is considered generally safe for most adults when used in recommended quantities for short periods. However, as with all supplements, some may experience side effects or interactions:
- Drowsiness (especially if taken during the day)
- Headache
- Dizziness
- Stomach upset or nausea
- Fatigue
- Potential for vivid dreams or grogginess upon waking
Rarely, allergic reactions or severe side effects can occur. Consult a healthcare provider if new or challenging symptoms develop.
Safety tips:
- Avoid operating heavy machinery or driving after valerian use until you know your personal response.
- Do not combine with alcohol, sedatives, sleep medications, or certain anxiety drugs unless supervised by a physician.
- Pregnant and breastfeeding women should avoid valerian root unless directed by a medical provider.
- Children and adolescents: Use only under professional guidance.
Long-term safety beyond several months of regular use is not well studied; intermittent use is generally advised.
Can You Take Valerian Root Every Night?
Most studies and expert guidelines suggest valerian can be used nightly for up to several weeks or a few months to manage specific symptoms (e.g., insomnia, PMS, menopause). For chronic, ongoing use, discuss plans with a licensed healthcare professional.
- Intermittent use may lower risks of tolerance, dependence, or diminishing effects.
- If sleep problems persist longer than 2–4 weeks, consult a doctor to rule out underlying conditions.
Do not abruptly stop high-dose, prolonged use; tapering may be advisable to minimize withdrawal-like symptoms.
