Got this for Rs 182 + 100 delivery charge - 250gm. It is in a glass bottle and packaging was excellent and Amazon delivery was prompt.
As for taste, didn't feel any hint of preservatives or any other chemical. There is no air tight tin foil on the opening but the cap was sealed externally by plastic cover. Manufacturing date was in November 2016 itself, the month which I ordered. (see attached pics)
As for health benefits, there are various purposes and benefits of this Amla rasayan and it works differently for different people. This can be observed only after a prolonged usage (at least 3 months) so don't expect any immediate results in short while out of it.
To add on, on my personal observation, after using for 4 days it did make my digestion better.
Excellent product. Good taste. The feel of purity is the main characteristic. We used it for our one-year baby. Thank you very much for making this quality product, that we expect from only the most trusted traditional Vaidyan (doctor), available online
