[spottysox]

Help dd (6) just ate a crystal given to her by her friend. It is made from Quartzite rock and potassium aluminium Sulphate does anyone know if I should take her to hospital
the friends dad said the instructions said drink water and get medical advice( waiting for nhs to call back) but thought the all knowing MN may be quicker. It was the size of a small pea if that makes any difference
Thanks

When ds ate a Karvol capsule a few months ago, NHS direct were very helpful and phoned their poisons unit to find out what we should do.

I'm sure they will do the same for you.
