What is valerian?
Valerian (Valeriana officinalis) is a European medicinal plant traditionally recognized for its calming and sleep-promoting properties. Its roots contain the highest concentrations of active compounds: valepotriates, valerenic acids, flavonoids, and lignans.
Its use has been documented since ancient times and is recognized by the European Medicines Agency (EMA) for the relief of mild mental stress and sleep disorders. It acts on the brain’s GABAergic system, promoting relaxation without significant daytime drowsiness at usual doses. For herbal medicine in general, additional resources are available.
What are its recognized benefits?
Valerian is traditionally used to:
- Help you fall asleep: reduced time to fall asleep, as documented by several studies
- Improve sleep quality: fewer nighttime awakenings, deeper sleep
- Relieve nervousness and mild mental stress
- Relieve restlessness, irritability, and muscle tension
- Supporting hormonal changes (menopause, premenstrual syndrome)
The effects are cumulative: they take effect after 1 to 2 weeks of regular use, unlike immediate-acting chemical sleeping pills. Specific resources are available for sleep and stress in general.
In what forms should it be used?
Several dosage forms are available:
- Root tea: 1 teaspoon per 250 ml of simmering water, steep for 10 minutes; drink 1 to 2 cups in the evening (the strong taste is characteristic)
- Dry extract capsules: 300 to 600 mg in the evening for sleep, 150 to 300 mg 1 to 2 times a day for stress
- Tablets containing standardized valerenic acidextracts for a consistent dosage
- Mother tincture or hydroalcoholic extract: 30 to 50 drops in a little water (contraindicated for children)
- Combinations with passionflower, lemon balm, hawthorn, or escholtzia for a synergistic effect
A typical course of treatment lasts 2 to 4 weeks, followed by a 1-week break. For passionflower, lemon balm, andhawthorn in general, specific resources are available.
What precautions should be taken?
Valerian remains a potent herb that should be used only when appropriate:
- Pregnancy and breastfeeding: Use is contraindicated without medical advice
- Children: Not recommended for children under 6; use with caution and consult a pharmacist for children between 6 and 12 years of age
- Driving and operating machinery: exercise caution at the start of treatment; reflexes may be slowed
- Drug interactions: may enhance the effects of sedatives, sleeping pills, anxiolytics, antidepressants, sedating antihistamines, and opioids (medical advice required)
- Avoidalcohol during treatment (potentiating effect)
- Limited duration: Do not exceed 4 weeks without a break
- Possibleside effects: daytime drowsiness at high doses, mild digestive upset at the start of treatment, rarely headaches
Use does not lead to physical dependence at the recommended doses and for the recommended duration. For nervousness andanxiety in general, specific resources are available.
How can you incorporate it into your daily routine?
To fully benefit from its effects:
- Sleep: Take 30 minutes to 1 hour before bedtime
- Stress: Take 2 doses spread out throughout the day (after meals)
- Take for 2 to 4 weeks, with breaks in between
- Relatedsleep hygiene: regularsleep schedule, cool bedroom, screens turned off 1 hour before bedtime
- Regularphysical activity and limiting caffeine after 2 p.m.
- Heart coherence or meditation as a complementary approach for stress
Valerian remains a temporary aid and does not replace the need to identify the underlying causes of stress or insomnia. If symptoms persist beyond 4 weeks, or if you experience overwhelming anxiety or marked sadness, a medical consultation is necessary. Your pharmacist remains a valuable resource for recommending the most appropriate form of the product, identifying potential interactions, and providing guidance during the first few weeks, in addition to appropriate medical follow-up. For linden in general, specific resources are available.
