(Pro 16:24 KJV) Pleasant words are as an honeycomb, sweet to the soul, and health to the bones.
Do you have sick “bones” (6106)? There are five times the Hebrew word is used in Proverbs and six times the English word is used. At one end you can have rotten bones. At the other end you have healing and refreshment that come to the bones. Sick bones is not something I want.
I can surround myself with people who offer healing words. I can use healing words myself. My first reading was that this would come from others but on reading it again and checking the context I think it can also apply to our speech.
So? People should be healthier after they have been around us.
