This is a safe sure step to take towards self healing. There is no toxicity, and there are no problems caused by taking regular dosages of a cell salt that is not needed -- it just won't work. As a general statement it is often said that you cannot overdose on cell salts or homeopathic remedies. However, we advise using cell salts as directed. Various situations have been experienced and reported from individuals taking too many cell salts all at once. Standard dosages are two dissolvable tablets, taken sublingually unless otherwise specified. Cell salts are designed to be administered over several months to cause a permanent effect so it should be clear that taking too many cell salts all at one time will not speed up the process. If you feel you may have taken too many cell salts and are experiencing trouble, consult a holistic practitioner immediately.
