In my personal experience everything that comes from a realized individual is supreme medicine. Even corpse salt from a high Lama is a wonderful medicine for ones practice.
The best example I have is from being plumber. I was fixing the sewer pipes of a high Lama. He had not been informed of my work and took a shower while I was working on it. As I was scrambling around I noticed the water seemed to have a luminous quality. I had no idea who was using the water but reached out and touched it. Instantly my mind was calm and vast like space. Like I had spent many weeks in deep retreat. It stayed like that for a few days. It did not matter what I did. My mind did not move. Erotic thoughts, sleepiness or watching TV it all felt the same.
I asked the Lama about it. He said that yes it was normal, but Lama's usually do not give those kind of blessings. It does not last and he considered it showing off.
If that is what bath water will do I can't imagine how powerful those other substances mentioned would be.
