Of course it is safe and wont harm you. It is only water. Good luck with treating cancer with it!

Seriously, stop pushing homeopathy as a cure. If one person stops having a real treatment to use homeopathic treatments you will have seriously harmed them. 

I like Big Pharma as little as anyone else but homeopathy is laughable. Do some math, by the time you stop diluting things there is **absolutely nothing**, sometimes not a single molecule of the active principke in that glass of water. And no, water doesn't have "memory".  

 If anyone stops using synthetic and toxic petroleum based  pharmaceuticals in favor of harmless homeopathy, they could only possible benefit from it, that is the point.

In regards to water having memory, there is quite a well known experiment showcasing that many different things can influence the structure of water. Call it "memory" or not but there definitely is something at work. https://www.youtube.com/watch?v=1qQUFvufXp4
