It is a Homeopathic medication! It may be a waste of money since to be a homeopathic medication the active ingrediant is diluted to 1/10000000000000000000000000000000000000000000000000000000000000 (10 to the 60th power). At 10 to the 24th power (Avagadro’s constant) the solution has a 60% probability of containing one molecule of original material if one mole of the original substance was used.
No. If it were diluted as per homeopathic medicine it wouldn’t (ever) work and there wouldn’t be the olfactory side effects. The zinc is labeled as 1x and 2x in the product I have.
