I read about this - sometimes it can be just a side-effect of stretching (if so skin preparations will relieve it), and other times it can be a symptom of stress to your liver, which can be quite serious (and won't be helped by moisturiser or other skin treatments). Can't remember what the specific name of it is. You should see your dr or midwife about it as well.

It's not that what your naturopath has given you won't help, and yr doc might be happy for you to keep taking it, but depending on what she's given you, some naturopathic liver cleansers/tonics may not fix the problem quickly enough, especially when dealing with pregnancy.

Good luck!
