Definition of Pishti
The medicine prepared from detoxified and purified drug substance by grinding in the mortar and pestle with liquid medicine like rose water etc. is called Pishti in ayurveda.
Pishti is a fine powder of medicine that absorbs in human body easily and has similar efficacy like Bhasma medicines.
Some Pishtis are kept under the light of the moon for improving their cooling characters. The cooling characters mean it is likely to reduce the heat and burning sensation in the body. Some may be kept under sunlight.
The same purified drug substances can be used for making Pishti as used for making Bhasma. The difference is in preparation method and cooling potency.
Absorption & Assimilation
Like Bhasma, Pishti also has quick absorption and assimilation because of micro-fine particles. It is gentler in action than Bhasma medicines.
Gemstones are preferred for making Pishti than Bhasma because it is traditionally believed that making Bhasma can cause loss of money and peace of mind. However, Pishti calms the mind and improves mental energies.
