Benefits & side effects

TRADITIONAL VIEW, WITH SAFETY LIMITS

Hindi name: Pithavan

What the texts say Prishniparni does

What the evidence says. Traditional use is extensive and long recorded. Modern clinical evidence is limited.

Side effects and limits

Avoid or ask first: No absolute contraindication is documented here. This is written deliberately rather than left blank.

A traditional classification, not a recommendation. The full safety record is below.

Stands in 6 groups

A Samhita can only be read forwards, from the group to its members. This is the same list read backwards.

AS THE CLASSICAL TEXTS AND THE API PRESCRIBE

Churna3–6 g
Kwatha50–100 ml
AnupanaUshnodaka · Dugdha
KalaAdhobhakta

One of the Dashamoola and of the Laghu Panchamoola.

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

Uraria picta. Constantly interchanged with Shalaparni, its pair in the Dashamula.

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.

Prishni means spotted or dappled and parni means leaved: the name describes the mottled leaf, which is the identifying feature and the reason the English name is painted-leaf uraria.

Gives the rasa, guna, virya and vipaka of prishniparni.

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.

Adulterants and substitutes

This is the clearest example in Dashamoola of a name that means different plants in different places. In the north Prishniparni is Uraria picta. Across much of the south it is Pseudarthria viscida, and both usages are old and settled. Neither seller is lying. A student should know that a Dashamoola preparation made in Kerala and one made in Uttar Pradesh may not contain the same ten plants, and that this is documented rather than scandalous.

Identity

Matched live against the GBIF backbone on 28 September 2026 at 99 per cent confidence. One of the ten roots of Dashamoola, counted among the five lesser roots. In parts of the south Pseudarthria viscida is used under this name instead, and that substitution is discussed below.

A WAY TO REMEMBER IT

Uraria is oura, a tail — the flower spike is a long soft tail. Picta means painted, for the variegated leaf. Prishni-parni means speckled-leaf, saying the same thing.

What the tradition holds

Prishniparni is counted among the Laghu Panchamoola in the Sushruta Samhita. That is what the tradition holds and where it is written down, not a finding about what the root does in a body.

Constituents. The root carries flavonoids and alkaloids. Composition differs between Uraria picta and Pseudarthria viscida, which is the practical consequence of the naming problem above.

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 often does not say which of the two plants was used, which makes it difficult to read across studies.

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. It is almost always used as one of ten roots rather than alone. Anyone on medication, pregnant, or managing a diagnosed condition should speak to a doctor or a qualified practitioner first.

Side effectsDigestive upset
ContraindicationsNo absolute contraindication is documented here. This is written deliberately rather than left blank.
InteractionsNo specific interaction is documented here. Anyone on regular medication should still tell their doctor what they are taking.
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, in grassland and open forest.
SoilWell-drained ground.
PlantingGrown from seed; a legume.
HarvestRoots lifted from plants of at least a year, washed and dried in shade.
What is not statedUraria picta is under collection pressure from Dashamoola demand and is listed as threatened in several Indian states, which is a reason to prefer cultivated material where it can be had.
