Parthiva · mineral origin · Maharasa

SHODHANA — NO MINERAL DRAVYA IS USED RAW

Heated red hot and quenched repeatedly in kanji, kulattha kwatha, gomutra, takra and tila taila, seven times in each, by the standard nirvapa method. Marana follows with gandhaka or with herbal media as the yoga requires.

Benefits & side effects

TRADITIONAL VIEW, WITH SAFETY LIMITS

What the texts say Vaikranta does

What the evidence says. Traditional use is documented in the Rasashastra texts. Modern evidence about this dravya is largely toxicological rather than therapeutic.

Side effects and limits

A silicate mineral, and silicates are not absorbed in the way the heavy-metal dravya are, so the toxicological concern here is smaller than for the arsenic and mercury minerals. The real risk is what is sold under the name: coloured glass and quartz pass every visual test. Anyone pregnant, on medication or managing a diagnosed condition should speak to a doctor or a qualified practitioner first.

Avoid or ask first: Not used in the raw, unprocessed state. This is written deliberately rather than left blank.

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

AS THE CLASSICAL TEXTS AND THE API PRESCRIBE

AnupanaMadhu · Ghrita

As bhasma, within a yoga. Never the raw mineral.

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.

Adulterants and substitutes

Coloured glass and quartz are sold as Vaikranta, and because the classical description is of a many-coloured crystal, colour alone is no test at all. The hardness and the eight-faced habit are the classical checks; an X-ray diffraction pattern is the modern one, and a supplier who cannot say which tourmaline species was used has not identified the mineral.

Identity

A silicate mineral of the tourmaline group, usually given as a complex boro-silicate of aluminium with iron, magnesium, lithium or sodium. The classical description is of a hard, many-coloured crystal resembling a diamond.

A WAY TO REMEMBER IT

Vaikranta is from vi-kranta, that which has stepped beyond - the mineral that stands in the place of the diamond. Tourmaline is from the Sinhala turamali, a name for mixed gem gravels.

What the tradition holds

Vaikranta heads the maharasa varga in the Rasa Ratna Samuccaya and is named there as the substitute for Vajra. That is what the tradition records and where it is set down.

Constituents. A silicate mineral of the tourmaline group, usually given as a complex boro-silicate of aluminium with iron, magnesium, lithium or sodium. The classical description is of a hard, many-coloured crystal resembling a diamond.

What the evidence says

StatusTraditional use is documented in the Rasashastra texts. Modern evidence about this dravya is largely toxicological rather than therapeutic.
SuggestedThe dravya has a defined place and a defined shodhana in the classical Rasashastra literature, and the processed form has a pharmacopoeial standing in India. That is a standard for the material, not evidence of an effect in a body.
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 analyses of preparations containing this dravya rarely record whether shodhana was performed or how, so a result cannot be attributed to the processed article rather than the raw mineral.

Safety

A silicate mineral, and silicates are not absorbed in the way the heavy-metal dravya are, so the toxicological concern here is smaller than for the arsenic and mercury minerals. The real risk is what is sold under the name: coloured glass and quartz pass every visual test. Anyone pregnant, on medication or managing a diagnosed condition should speak to a doctor or a qualified practitioner first.

ContraindicationsNot used in the raw, unprocessed state. 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 - the mineral dravya have almost never been studied for interaction with modern medicines.
Pregnancy and breastfeedingSafety in pregnancy has not been established, and no mineral bhasma should be taken in pregnancy except on the decision of a qualified practitioner who has examined the person.
