The classical raktapradara and stambhana bark.

Reported from Sharangadhara Samhita and the Ayurvedic Pharmacopoeia of India. Laisha states what the texts prescribe; it does not recommend. No quantity here is adjusted for a particular person — not for agni, koshtha, bala, age, pregnancy, kidney or liver function, or anything already being taken.

Foreign matter

Symplocos racemosa bark. Several Symplocos species are traded together and the bark is difficult to separate on sight.

These are the marker and the identity test for this dravya, and they are not a test Laisha has run on anything. Laisha does not state the numeric limits here: the assay, ash and extractive figures must be read from the current edition of the Ayurvedic Pharmacopoeia of India, because a wrong limit printed here is a number a laboratory would act on. The entries in this library that DO carry figures carry them because each one was checked.

Why it mattersThe bark is the dravya. It was also a mordant for dyeing, which is why it was collected at scale long before it became scarce.

Classical references

Charaka Samhita
Sutrasthana, chapter 4 (Shadvirechanashatashritiya)
Lodhra is named among the dravya of the chapter.
Bhavaprakasha Nighantu
Vatadi Varga
Gives the rasa, guna, virya and vipaka of lodhra and distinguishes its kinds.
Sushruta Samhita
Sutrasthana, chapter 38 (Dravyasangrahaniya)
Included among the dravya grouped by action.

Rasa, guna, virya, vipaka and karma are recorded as the classical texts give them, with the text and section named so a student can open the book and check. Where an exact chapter and verse could not be confirmed, this library names the section rather than inventing a number.

Formulations it appears in

Adulterants and substitutes

Symplocos species other than racemosa are collected and sold as lodhra, and because the tree is threatened and the bark is in constant demand for women's formulations, substitution is routine. Bark of unrelated astringent trees is also used, and once dried and cut, astringency is the only property most buyers test.

Identity

Matched live against the GBIF backbone on 28 September 2026 at 99 per cent confidence. Assessed as threatened under collection pressure, and heavily substituted for that reason.

A WAY TO REMEMBER IT

Symplocos is symploke, an interweaving — the stamens are joined at the base. Racemosa means the flowers are in a raceme.

What the tradition holds

Lodhra is described in the Bhavaprakasha Nighantu and named throughout the classical literature for bleeding. That is what the tradition holds and where it is written down, not a finding about what the bark does in a body.

Constituents. The bark carries tannins in high proportion and the alkaloid loturine.

What the evidence says

StatusTraditional use is extensive and long recorded. Modern clinical evidence is limited.
SuggestedHealth Canada publishes monographs covering Ayurvedic ingredients and permits specific traditional-use claims, which reflects a regulator accepting a documented tradition rather than a body of clinical trial evidence.
Not establishedThere is not enough good clinical evidence to establish an effect on any named health condition. Long traditional use is not a substitute for that evidence, and this library does not present it as one.
The honest gapPublished work is limited and rarely confirms the species against the substitutes described above.

Safety

The important caution is the same as for ashoka, and for the same reason: this dravya is used where a woman is bleeding abnormally, and abnormal bleeding is a symptom with causes ranging from the trivial to the grave. Finding the cause comes before choosing a herb. It is tannin-rich, so constipating and capable of reducing iron absorption — which matters particularly in someone who is bleeding and may already be anaemic. Anyone on medication, pregnant, or managing a diagnosed condition should speak to a doctor or a qualified practitioner first.

Side effectsConstipation from the tannins
Digestive upset
ContraindicationsPregnancy.
InteractionsNo specific drug interaction is documented for this dravya. That is the honest state of the evidence, not a statement that none exists — most Ayurvedic dravya have never been studied for interaction. Tell the prescribing doctor it is being taken.
Iron supplements and any oral drug — tannins bind them and reduce absorption. Separate by two hours.
Oestrogen-sensitive conditions — the classical use in raktapradara is the reason to ask before combining it with hormone therapy.
Pregnancy and breastfeedingNot to be used in pregnancy without a qualified practitioner. There is not enough evidence to establish safety in breastfeeding.
Abnormal bleeding is a symptom, not a diagnosisThe presentation this dravya is traditionally used for has causes ranging from harmless to serious. Reaching for a herb instead of finding the cause is the hazard, and it matters more here because a bleeding person may already be anaemic and this bark reduces iron absorption.
Threatened and heavily collectedSymplocos racemosa is assessed as threatened under collection pressure for its bark, which is what drives the routine substitution described above.

Growing it

ClimateSubtropical hill forest, chiefly the Himalayan foothills and the Western Ghats.
SoilMoist, well-drained hill ground.
PlantingA small tree, raised from seed.
HarvestBark taken in strips from part of the trunk so the tree survives.
What is not statedAssessed as threatened under bark collection pressure. Cultivated material should be preferred where it can be had.
