Is it unethical and maybe have karmic consequences to send people healing without them specifically asking for it?

I use the elemental of the Aloe plant to give healing to me and my family but also to other people who I hear about who are suffering. I always state, only do this healing if it is in alignment with divine will and the law of karma. But, I seen on a Shamanic facebook page where a question similar was brought up and someone stated that sending healing without the person specifically asking for it is highly unethical.

What are your opinions on this?

Thanks
