AS THE CLASSICAL TEXTS AND THE API PRESCRIBE
| Beeja churna | 1–3 g |
| Pushpa kwatha | 50–100 ml |
| Niryasa | 0.5–1 g |
| Anupana | Takra · Ushnodaka |
| Kala | Pragbhakta |
The SEED is the anthelmintic and is the part with the narrow matra; the gum is a stambhana.
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.

| Prabhava | The texts name palasha beeja among the first dravya for krimi, and its action against worms is treated as prabhava. |
| Doshakarma | Kaphavatahara. Being ushna it increases pitta. |
Katu, tikta and kashaya with ushna 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 | Beeja (the seed) Pushpa (the flower) Twak (the stem bark) Niryasa (the gum, Kamarkas) |
| Why it matters | The seed is the medicinal article and is used against worms. The flower, the bark and the red gum — Kamarkas — are separate articles with different uses. |
Kimshuka means what-parrot, from the flower's resemblance to a parrot's beak — the identification is in the name. Yajniya records its use in ritual; the wood is used for the sacred fire.

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.
| Palasha Beeja Churna | Named for the seed. |
| Krimighna Vati | Palasha seed is among the dravya. |
| Kamarkas | The gum, used as a separate article. |
Butea superba and Butea parviflora are collected and sold under the same name. The gum, Kamarkas, is adulterated with cheaper gums and with resin, which is hard to see in a dried lump.

A WAY TO REMEMBER IT
Butea honours the Earl of Bute. Monosperma means one-seeded — the pod holds a single seed. Palasha is the flame of the forest.
Palasha is named among the Krimighna dravya in the Charaka Samhita and described in the Bhavaprakasha Nighantu with its several parts distinguished. That is what the tradition holds and where it is written down, not a finding about what the seed does in a body.
Constituents. The seed carries palasonin and proteinaceous material; the flower carries butein and butin, which give the orange dye.
| 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 separates the seed from the other parts, which the tradition treats as distinct. |
The seed is the strong part and it is not a gentle article. Taken in quantity it causes vomiting and digestive upset, and it has a documented action on fertility — palasonin has been studied for antifertility activity, which is why this entry does not treat it as neutral for anyone trying to conceive. Worm infection is also a laboratory diagnosis rather than a guess, and the wrong thing may be being treated. The flower and bark are milder. Anyone on medication, pregnant, or managing a diagnosed condition should speak to a doctor or a qualified practitioner first.
| Side effects | Nausea and vomiting Digestive upset Loose stool |
| Contraindications | Pregnancy. Anyone trying to conceive, in light of the above. |
| Interactions | No specific interaction is documented here. Anyone on regular medication should still tell their doctor what they are taking. |
| Pregnancy and breastfeeding | Not to be used in pregnancy or breastfeeding. |
| Climate | Tropical, in dry deciduous forest; extremely hardy. |
| Soil | Wide range including poor, dry and saline ground. A legume. |
| Planting | A tree, raised from seed. |
| Harvest | Flowers collected in spring. Pods collected when dry and the single seed removed. Gum tapped from the bark. |
| What is not stated | This 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. |
