ACIDIC VALUES OF OILS

Dear Drs.,
I have a query regarding acid value of oil.
I understand that the higher the acid value of edible oil, it impacts the heart. But of what importance is acid value of oils like naryana taila or ksheerabala taila. And on what basis is it standardised in AFI?
Dear Dr Nitin,
If you see the composition of Ayurvedic oils they will have a base oil --like Sesame oil --which is on a higher acidic value or coconut oil --with medium chain fatty acids and a lower acidic value.
When we do a moorchana --we mix oleoresins of various herbs in the base oil .
The oleoresins may be alcoholic, phenolic, esters, ethers, terpenoids, ketones, sesquiterpenes which are complex organic compounds.
These compounds affect the overall ph of the oil.
So most of the oils which reduces vata and kapha-- should have a higher aciidc value
----while oils like ksheerbala which reduces pitta dosha or oils which work on rakta dhatu should have a lower acidic ph.
As of now there is no standardization because the chemistry is still poorly studied.
The more acidic oils (oils pacifying vata and pitta) will act as irritants leading to increased blood circulation to that specific area.
The same helps in washing off of toxins or antigen antibody complexes (Aam) and clearing of the vata channels leading to cleansing.The less acidic oils (pitta pacifying oils) soothes the tissue and provide rest to the already inflamed area leading to pitta shaman.

Dr.Nitin ji,

Acid value or the acid numbers are the European standards and is presumed that fats available in oils converts into fatty acids thus increases the acid numbers, but this can not be applicable on Tail standardization as Tail Murchhan is entirely different with modern oil preparations.

As far as standardization in AFI is concerned there is no specific method are described, only method of prepration of oil is standradize in general and specific references are given for the individual Tail process if some thing different is there.

Both Tail you mentioned here totally have pure classical references in AFI also.1.Ksheerr bala tail -अष्टांग संघ्रह -वात रक्त चिकित्सा-अध्याय २२:४५-४६.(AFI-Part-I)2.Narayan Tail-भैश्यज्य रत्नावली -वात व्याधि अधिकार (AFI-Part-I).There are certain parameters which are not possible to measure on modern scientific methods so are not necessary to standardize.

Thanks
