Mostly harmless
I assume that a 1X solution is a ten-fold dilution of the mother tincture. Sheikh has posted elsewhere recently that to prepare a mother tincture of belladonna, you put the plant itself into a water/alcohol mixture and leave it to infuse for a while (several weeks, perhaps? I'll have to look for the post in question). So in this case, your 1X preparation will obviously contain much less than 10% of chemicals from the belladonna. Of course, it's impossible in this scenario to say exactly how much there will be.As far as I know (correct me if I'm wrong), homeopathic remedies are generally administered via a number of drops, so maybe it could be assumed that each drop is 0.1g of liquid (as a wild stab in the dark), and hence a single drop dose of a 1X solution could contain up to 10mg of active ingredient (assuming 0X is pure ingredient). That's a non-negligible amount in real terms.
