Observations from Pottali kalpa

• Pottali paka should be done only on Mandagni in Vidruta Gandhaka as advocated by Acharyas. Gandhaka should attain Vyoma Varna as in this state Sulphur becomes solidified and will produce a good quality NON FRIABLE Pottali.

• Monitoring of Agni with a thermometer timely from 120oC to 220 C(Vyoma varna) is a must to attain correct paka.

Observations from Pottali kalpa

• During paka ingredients are saturated with gandhaka.• This helps in increase in shelf life • After consumption as it is less soluble and absorbs

gradually after ingestion, increases the safety of the drug. (aborts upadrava)

• Though during preparation Rasa is used, no traces of Rasa(mercury) are found in finished product. This suggests that Rasa acts as only Yogavahi(catalyst) in the whole process.

Benefit of Pottali.

• The ultimate advantage of Pottali over conventional Bhasmas is in its ability to preserve the therapeutic efficacy of Bhasmas for a long time, with out compromising on the basic quality parameters of Bhasma viz., nischandra, rekhapurna and varitara.

Benefit of Pottali. Conclusion

• Contrary to popular belief that Bhasmas have eternal potency, in practice it is observed that they also tend to degrade, become toxic if not preserved properly. Hence the need of pottali kalpana.

• Pottali kalpana should be looked at as advanced rasashastra (pharmaceutical technique) to increase the shelf life, therapeutic effects and safety of Bhasmas.
