Shilajit is so valued in the Orient that it is tough to get the "good stuff" because the Japanese and Chinese snag the majority of production from India before it reaches the West. I first tried this when I ordered the Kidney Stone Remedy kit at stoneremedy dot com-- this is the exact formulation they use in their remedies, at a REALLY low price here on Amazon (lower than anywhere else I've found). If you Bing or Google the key words stone remedy, the above formula at stone remedy dot com comes up in ORGANIC (not advertised) search results above 21 million results-- Amazon will save you hundreds over those offers with the Jarrow formula. Buying it at Amazon is fast (especially if you are Prime), and the dating is very fresh, although frankly Shilajit is one of the few herbs that get better with age. I've set up one of those automatic monthly order deliveries on Amazon to stay in stock. I used to get it at Vitacost also, but Amazon's service and price are WAY better, and shipping is free with Prime. I've had kidney stone problems on and off for years, including surgery and many of those agonizing hospital visits (often at $12,000 plus each time), and Shilajit has stopped them dead in their tracks. Of course I also have to drink a lot of water and keep calcium down and oxylates to a minimum (peanut butter, chocolate and raspberries gone-- my favorite foods! Dropping the spinach wasn't as tough ;=)), but the fulvic acid and Shilajit-- which is an age old tar acid from the Himalayas-- has been the key for me. I can't honestly comment on all the other benefits claimed for this herb, which are many, but if you have, or know someone who has problems with Stones, check with your Urologist and then try this! Does no harm as a natural herb, but boy it sure zaps those stones before they get acute, at least for my type (calcium oxylate). Bless you if you've gone through it-- not fun, and I hope you never get another one
