Hmm… we have a conundrum here: We use E Jiao (donkey hide) a fair amount and are looking into alternatives for each of the formulas that use it. As well, in general, we have more and more trouble importing any animal products. We are trying to use Sheng Di Huang instead and also exploring with our distributors other options. Sheng Di has many of the qualities of E Jiao – if you need E Jiao we can do it.

Here you can read about the problem on the Guardian web site.
