AS THE CLASSICAL TEXTS AND THE API PRESCRIBE

| Kwatha | 50–100 ml |
| Anupana | Madhu · Ushnodaka · Tandulodaka |
| Kala | Adhobhakta |
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.

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.

| Prabhava | The texts treat lodhra as the chief dravya for raktapradara and name it in almost every formulation for bleeding in women. |
| Doshakarma | Kaphapittahara. Being ruksha it increases vata. |
Kashaya and tikta with sheeta virya and katu vipaka.
These are the actions the classical texts record. They are statements about what the tradition holds, and this library does not restate them as findings about a human body.
| Upayukta anga | Twak (the stem bark) |
| Why it matters | The bark is the dravya. It was also a mordant for dyeing, which is why it was collected at scale long before it became scarce. |
The texts distinguish several lodhra — Shabara lodhra is generally taken to be this species and is the one used medicinally, while other kinds were dye materials.

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.
| Pushyanuga Churna | Lodhra is a principal dravya. |
| Lodhrasava | A fermented preparation named for the dravya. |
| Nyagrodhadi Kwatha | Lodhra is among the dravya. |
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.
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.
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.
| Status | Traditional use is extensive and long recorded. Modern clinical evidence is limited. |
| Suggested | Health 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 established | There 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 gap | Published work is limited and rarely confirms the species against the substitutes described above. |
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 effects | Constipation from the tannins Digestive upset |
| Contraindications | Pregnancy. |
| Interactions | No 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 breastfeeding | Not to be used in pregnancy without a qualified practitioner. There is not enough evidence to establish safety in breastfeeding. |
| Climate | Subtropical hill forest, chiefly the Himalayan foothills and the Western Ghats. |
| Soil | Moist, well-drained hill ground. |
| Planting | A small tree, raised from seed. |
| Harvest | Bark taken in strips from part of the trunk so the tree survives. |
| What is not stated | Assessed as threatened under bark collection pressure. Cultivated material should be preferred where it can be had. |
