Vick 's is a lot more effective, and a lot less PAINFUL. Have you by chance ever used a mustard plaster? If used improperly, not only can you BURN your flesh.But blister and permanently scar the area it's used on. But after looking at your avatar, maybe you SHOULD use one yourself! So few people remember the damage mustard gas alone caused in WW I let alone the most recent use of it in Iraq. Sorry to come on so harshly but ive seen the damage an improperly applied plaster can cause. :(
vicks is excellent but i find it too strong and sticky when put on your chest so smother it on a tissue, fold the tissue over and put it under your pillow case, so when you sleep at night you are breathing it in.
