Take it nightly for about two weeks before deciding whether it works. It isn't a one-dose remedy.
It is stronger than passionflower and can leave some people heavy-headed in the morning.
The smell is genuinely unpleasant. That is normal and not a sign of a bad product.
Valerian is one of the few sleep herbs with a genuine place in classical Persian medicine, where it's called sonbol-ot-tib. Avicenna wrote about it for nervous complaints and for pain. The modern picture is honest but messy: several trials show people report falling asleep more easily and rate their sleep as better, but objective measurements in a sleep lab often show much less change than the person's own impression. Reviews conclude the evidence is modest and inconsistent. It is also slow — most traditional and modern practice expects two weeks of nightly use before judging it.
Known to botanists as Valeriana officinalis.

The Plant Itself
Valerian is a tall meadow plant with clusters of small pink-white flowers that smell sweet. The root doesn't. Dried valerian root has a heavy, earthy, unmistakable smell that most people describe as old socks. The root and rhizome are the parts used, dug in autumn of the second year. Related Iranian species grow wild in the Alborz mountains.
Family: Caprifoliaceae (honeysuckle family).

Why Herbalists Still Reach for It
Sleeping tablets carry real costs, especially past sixty: dependence, falls, foggy mornings. Valerian is one of the oldest alternatives with both a classical Persian pedigree and modern trials. It isn't as strong, and it doesn't work for everyone, but it's a reasonable thing to try first while you fix the other causes of bad sleep.
Sleep changes with age, and the medicines usually offered for it are the ones most likely to cause a fall at three in the morning. Valerian is a gentler option with a long record in Persian practice. It works best when it's one part of a whole approach: daylight in the morning, movement in the day, a dark and cool room, and a doctor's eye on anything that won't settle.
People commonly report falling asleep faster and sleeping better (subjective measures in multiple trials).
Does not cause dependence in the way prescription sedatives (medicines that make you sleepy) can.

What Persian Medicine Says
Persian medicine calls sonbol-ot-tib warm and moist. It was used for anxious restlessness, for trouble sleeping, for cramping pain, and for palpitations from nervousness. Avicenna listed it among the calming roots. In Iranian folk practice it's often combined with lemon balm and borage as an evening drink for the heart and nerves.
It was used: difficulty falling asleep; cramping pain, including menstrual cramps.
Traditional use for anxious restlessness.
Valerian appears in Persian, Greek, Arabic and European pharmacies alike — one of the genuinely shared medicines of the old world. Galen recommended it. In wartime Britain it was given for shell-shock and air-raid nerves. In Iran it remains a common pharmacy tincture (a liquid extract made with alcohol) sold under its classical name.

What Is In It
Valerenic acid is the marker compound, shown in laboratory work to act on GABA-A receptors, the brain's calming system.
Valepotriates: unstable compounds that break down as the root dries, which is why fresh and old products differ.
Isovaleric acid is the source of the notorious smell.
Lignans (fibre-linked plant compounds found in seeds) and flavonoids — minor constituents that may add to the sedative effect.

How It Is Prepared
Cold infusion (a drink made by steeping the plant in hot water): root steeped in cool water overnight, a gentler traditional method with less of the smell.
Nerve blend: valerian with lemon balm and borage flower.
Tea: one teaspoon of dried root steeped covered for ten to fifteen minutes, one cup before bed.

How It Is Prepared: Other Ways to Use It
Course: nightly for two weeks, then assess.
Take it thirty minutes to two hours before bed, every night for two weeks.
Blend it with lemon balm to soften both the taste and the smell.
Keep the rest of the bedtime routine steady — the herb works with habits.

Extracts, Capsules and Concentrates
Capsules and standardised extracts carry many times the amount you get from food, which is why the cautions below matter more here.
Tincture is the common Iranian pharmacy form, sold as sonbol-ot-tib drops.
Tincture: follow the label, taken in a little water in the evening.
Capsules: the easiest form if the smell is a problem.
Use a tincture or capsule if the tea smell defeats you.

Who Should Be Careful: The Rest of It
General caution:
Rarely, it has the opposite effect and makes a person restless. If that happens, stop.
Medication interaction:
Never mix with alcohol or prescribed sedatives.
Medication interaction:
Do not combine with sleeping tablets, benzodiazepines, or alcohol — the sedative effects add up.
Medication interaction:
Stop at least two weeks before surgery, as it interacts with anaesthesia.

Questions People Ask
Why does it smell so bad?
Isovaleric acid, which develops as the root dries. It is a sign of an ordinary, correctly dried root.
Can I take it just on bad nights?
You can, but most trials and traditional practice used it nightly for two weeks. Occasional use tends to disappoint people who then conclude it does nothing.
