AS THE CLASSICAL TEXTS AND THE API PRESCRIBE

Mocharasa, the dried gum, is the classical raktastambhana and is used in Pushyanuga churna.

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.

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 angaNiryasa (the gum, Mocharasa)
Mula (the root of a young tree)
Pushpa (the flower)
Kantaka (the thorn)
Why it mattersThe gum, Mocharasa, is the dravya most used. The root of a young tree, Semal musli, is a separate article, and the thorns from the young trunk are used externally.

Paryaya

MochaPicchilaKantakadhyaRaktapushpaSthiraayu

Kantakadhya, rich in thorns, names the conical prickles that cover a young trunk and are themselves used. Picchila, slimy, names the gum.

Classical references

Charaka Samhita
Sutrasthana, chapter 4 (Shadvirechanashatashritiya)
Shalmali is named among the dravya of the chapter.
Bhavaprakasha Nighantu
Vatadi Varga
Gives the rasa, guna, virya and vipaka of shalmali and describes the gum separately.
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

Mocharasa preparationsThe gum, used as its own dravya.

Shalmali PakNamed for the dravya.

Adulterants and substitutes

Mocharasa is a dried gum lump and is bulked with gum arabic, with tragacanth and with cheaper tree gums, none of which is visible once mixed. Semal musli, the young root, is substituted with Safed musli, which is Chlorophytum and a different family, because the names overlap in the market.

Identity

Matched live against the GBIF backbone on 28 September 2026 at 99 per cent confidence. Salmalia malabarica is a synonym. The tree whose red flowers cover bare branches before the leaves come, and whose gum — Mocharasa — is a separate dravya with its own name.

A WAY TO REMEMBER IT

Bombax is bombyx, silk — the seed floss. Ceiba is the Caribbean name for the related silk-cotton tree.

What the tradition holds

Shalmali is described in the Bhavaprakasha Nighantu, where the gum is treated separately from the tree. That is what the tradition holds and where it is written down, not a finding about what the gum does in a body.

Constituents. The gum carries tannins, mucilage and catechin. The root carries starch and mucilage.

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 on this dravya is limited and rarely distinguishes the gum from the root or bark.

Safety

No serious harm is documented for this dravya at traditional use, which is a statement about the absence of records and not a guarantee. The gum is grahi, so it can cause constipation, and its mucilage can reduce the absorption of medicines taken at the same time. The commonest practical problem is that a lump of gum sold as mocharasa may be largely something else. Anyone on medication, pregnant, or managing a diagnosed condition should speak to a doctor or a qualified practitioner first.

Side effectsConstipation
Digestive heaviness
ContraindicationsNo absolute contraindication is documented here. This is written deliberately rather than left blank.
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.
Any oral drug taken at the same time — the mucilage of Mocharasa slows absorption. Separate by two hours.
Antidiabetic medicines — mild lowering reported for Bombax.
Pregnancy and breastfeedingThere is not enough evidence to establish safety in pregnancy or breastfeeding, and a qualified practitioner should be asked first.

Growing it

ClimateTropical; a large deciduous tree, common across India.
SoilDeep, well-drained ground.
PlantingA tree, raised from seed. Fast-growing.
HarvestGum is collected from incisions in the bark and dried. Roots are lifted only from young trees, which kills them, so this is not a sustainable source at scale.
What is not statedThis library has not verified region-specific spacing, variety and yield figures against a named agricultural authority for every growing country, and does not state them rather than guessing.
