I personally visualize dark stagnant energy leaving the body and golden light from God/Universe filling up the empty spaces. Then visualize a golden cocoon of light that keeps illness at bay.
What you're asking is essentially a type of healing and energy work. The couple times I've asked the person needs to be aware and given you their consent for you to manifest good health on to them to be truely effective. Other times I believe that their mind/body/soul complex will accept your vibes or it will just go back to you if it doesnt. You can't out-manifest karmic wounds/disease--thats when a soul has made an intentional plan to have an ailment to learn something.
