It should be safe,if you think poison, but homeopatically thinking, its not safe, it can act supressive, and then we may have a risk for inflamations of the brain, and its not homeopathy, its a herbalists trick.
Homeopathy is individualization. not shotgunterapie, or supressive therapie, or symptome therapie like this is.
To find a fitting remedy, we need his disease historie, etc, take a look at other postings, it will give you a idea of what we need, in order to prescribe.
