Ashoka in other languages
Introduction
Ashoka (Saraca asoca) — the "remover of sorrow" — is Ayurveda's foremost herb for the uterus and women's health. Its bark cools and tones the female reproductive system and is the base of the classical Ashokarishta.
Classification
Of the Fabaceae family, Ashoka is grouped among the uterine-toning and Raktastambhaka (styptic) dravyas. Its astringent-bitter taste and cooling potency pacify Pitta and tone the Artavavaha channel.
Uses & benefits
Ashoka is Ayurveda's principal drug for the uterus, named in the texts as Stri-rogahara. It is used in excessive or painful menstruation, in Asrigdara (menorrhagia) and in the general management of uterine weakness. The bark is prepared as a decoction or taken as Ashokarishta, which is its commonest form.
Ashoka for heavy menstrual bleeding
Its best-established use. Strongly astringent, it is the classical drug for Asrigdara — excessive menstrual flow — and the reason Ashokarishta exists.
Ashoka for painful periods
Used in dysmenorrhoea for cramping pain, usually within a compound rather than alone. It calms the uterine muscle rather than acting as a painkiller.
Ashoka for irregular cycles
Taken over several cycles to regularise timing where periods are unpredictable. It is a tonic to the reproductive tissue, so it works slowly.
Ashoka for leucorrhoea
Its astringency checks white vaginal discharge, a classical indication that appears across the Nighantus.
Ashoka as a uterine tonic
Classical texts describe it as acting specifically on the Garbhashaya (uterus), which is why it appears in almost every traditional women's formulation.
Ashoka after childbirth
Used in the post-partum period to help the uterus return to tone and to reduce prolonged bleeding.
Ashoka for bleeding piles
The same Raktastambhaka (bleeding-arresting) action applied to haemorrhoids and other Raktapitta conditions.
Ashoka for skin complaints
Applied externally and taken internally in inflammatory skin conditions, on the classical principle that cooling the blood clears the skin.
Ashoka in Ashokarishta
The lead drug of the best-known women's tonic in the Ayurvedic pharmacopoeia, taken as a fermented liquid after meals.
Ashoka for pelvic discomfort
Used for a dragging or heavy sensation in the pelvis associated with menstrual disorders, again as part of a compound.
Dosage — how much to take
Bark powder 3–6 g or decoction; Ashokarishta is the common preparation. Follow your Vaidya's advice.
Dosage varies with age, constitution and condition — confirm with a qualified Vaidya.

Frequently asked questions
What is Ashoka used for in Ayurveda?
Ashoka bark is used almost entirely for women's reproductive health: heavy menstrual bleeding, painful and irregular periods, leucorrhoea, and as a uterine tonic after childbirth. It is the lead herb in Ashokarishta, the classical women's formulation.
How long does Ashoka take to regulate periods?
Classical practice expects two to three menstrual cycles before judging the effect. It works as a tonic to the reproductive tissue rather than as an immediate corrective, so it is taken continuously rather than only around the period.
What is the dose of Ashoka?
Bark powder 3–6 g per day, or decoction 40–80 ml twice daily. As Ashokarishta, typically 15–30 ml with an equal quantity of water after meals, twice daily, or as your physician directs.
Can Ashoka be taken during pregnancy?
Not without a physician's supervision. Ashoka acts on the uterus, which is precisely why it needs care in pregnancy. Its post-partum use is a separate indication and does not imply it is safe during pregnancy.
Does Ashoka help with PCOS?
It is often included in formulations for PCOS because of its effect on cycle regularity, but it does not address the metabolic side of the condition. PCOS needs a broader approach and proper diagnosis rather than a single herb.
Are there side effects of Ashoka?
Well tolerated at classical doses. Being astringent, prolonged heavy use may cause constipation. Persistent heavy bleeding always needs medical investigation to rule out fibroids or other causes — do not self-treat it indefinitely.
Is Ashoka an endangered tree?
Saraca asoca is under real pressure from bark collection and is listed as vulnerable in India. Look for products from cultivated or sustainably harvested sources, and be aware that adulteration with Polyalthia longifolia bark is common.
