Indian Valerian

BotanicalBest before bed

What is it

Indian valerian (Valeriana jatamansi, also called tagara) is a Himalayan species of valerian whose rhizome is used in traditional Indian medicine for sleep and anxiety. It is botanically distinct from the better-studied European valerian (Valeriana officinalis).

Evidence for 2 uses

AI-assisted evidence assessment — talk to your doctor before relying on any single supplement.

Sleep onset and quality

Limited Evidence

Small studies on V. jatamansi and broader evidence on V. officinalis suggest modest improvements in sleep quality, but trial quality is inconsistent and effect sizes are small. Most reviews conclude evidence is suggestive rather than definitive.

Anxiety

Mixed Evidence

Limited and mixed evidence from small trials and traditional use. Effects, when observed, are modest.

How it works

Like other valerian species, V. jatamansi contains valepotriates, sesquiterpenes (including valerenic acid analogues), and lignans believed to modulate GABA-A receptor activity and inhibit GABA breakdown. This is thought to underpin its mild sedative and anxiolytic properties. Most human evidence on valerian for sleep comes from Valeriana officinalis, not V. jatamansi. Small preclinical and a handful of small clinical studies on V. jatamansi suggest similar direction of effect, but the data are sparse and quality is variable.

Dosage

No established RDA. Traditional doses of the powdered root range from roughly 300 mg to 1 g taken 30-60 minutes before bed. Standardized extracts vary widely and labels should be the reference. There is no defined upper limit.

When and how to take it

Take 30-60 minutes before bedtime for sleep support. Daytime doses for anxiety, when used in traditional practice, are typically smaller. Effects may take 2-4 weeks of regular use to become noticeable.

2 commercial forms

Compare the main delivery options and what they’re best suited for.

Dried root powder (tagara)

Traditional Ayurvedic form, often combined with other calming herbs.

Active sesquiterpenes are reasonably absorbed orally; valepotriates are unstable and may degrade during storage.

Standardized rhizome extract

More consistent dosing than crude powder.

Standardization markers vary by manufacturer.

Safety

Generally well tolerated for short-term use. Reported side effects include morning grogginess, headache, dizziness, and GI upset. Long-term safety is not well characterized, and case reports of hepatotoxicity associated with valerian products exist, though causality is unclear.

Who should be cautious

Avoid in pregnancy and breastfeeding due to limited safety data. Use caution if you have liver disease or are taking sedative medications. Stop at least 2 weeks before scheduled surgery because of additive effects with anesthesia. Not recommended for children without clinical guidance.

Interactions

May potentiate the sedative effect of alcohol, benzodiazepines, barbiturates, opioids, and other CNS depressants. Theoretical interactions with substrates of CYP3A4 have been raised but are not well established for V. jatamansi.

Frequently asked questions

Is Indian valerian the same as European valerian?⌄

No. Both are in the Valeriana genus but are different species with overlapping but distinct chemistry. Most of the published sleep research uses Valeriana officinalis.

Will it make me drowsy the next day?⌄

It can, especially at higher doses. Start with a low dose and avoid driving until you know how it affects you.
