Last reviewed by the teas.co.uk team in May 2026.

What is valerian

Valeriana officinalis is a flowering plant native to Europe and Asia. The root and rhizome are dried for use in tea or supplements. It is the root, not the flower, that carries valerian's characteristic aroma.

The taste problem

Valerian root has a distinctive earthy, musky flavour that:

many drinkers find unpleasant;
cannot be masked entirely;
is usually combined with chamomile, lavender or fruit notes to soften it;
becomes stronger the longer it steeps.

UK valerian tea options

Pure valerian (rare)

Some specialty retailers offer pure valerian tea bags.

Valerian-led blends

Pukka Night Time (oat flower, lavender and valerian).
Twinings Sleep with Valerian.
Heath & Heather Night Time.
Clipper Snore & Peace (chamomile and valerian).
Yogi Bedtime Tea.

How to brew

1 bag in 200ml just-boiled water.
Cover the cup and steep 7-10 minutes; valerian root is slow to give up its character.
Drink 30-60 minutes before bed.

Caffeine

None. Valerian is naturally caffeine free.

Pregnancy and children

Valerian is best avoided in pregnancy and while breastfeeding, and is not recommended for children under 12. A plain chamomile blend is the gentler evening option if any of these apply.

Good to know

It is sensible not to combine valerian with prescription sleep medication, other sedatives, or a lot of alcohol on the same night, as the combination can leave you groggy in the morning. Check with your GP if you take regular medication.

FAQ

How to brew valerian well

Brew at full boil for 7-10 minutes; valerian root is slow-extracting, so a quick brew leaves most of its character behind. Cover the cup to keep the aromatics in. For loose root, use a teaspoon of dried root per cup and simmer it gently in a saucepan for 8-10 minutes rather than just steeping, then strain, the simmer draws far more out of the woody root. Sweeten lightly with honey if you want to soften the earthy note. Drink 30-60 minutes before bed, and give it a week or two of regular evening use rather than judging it on the first cup.

Curator's note: valerian is one of the better evidenced sleep supportive herbs. Distinctive flavour but real effect. Worth keeping a valerian based sleep blend for difficult sleep nights. Lee, Teas.co.uk, Tunbridge Wells.

The bottom line on valerian

Valerian is the herb at the heart of most UK sleep blends, with the trade-off of an earthy taste that takes some getting used to. Worth a try if you want a traditional evening wind-down cup, ideally as a nightly habit rather than a one-off. Skip it if you cannot get on with the taste, are on prescription sleep medication, or are pregnant.
