Hydrangea

Could you please tell me if there is any side effects of taking the herb hydrangea? I was told that it is useful for dissolving kidney stones and gallstones. If I suffer from gastritis, then could I take this herb?

Yes, hydrangea is used to dissolve kidney stones, and should not be upsetting in gastritis. For gastritis, you could add a soothing remedy such as Slippery Elm powder or Marshmallow root.
