How to defeat the trio of Crown Chemical Co. apothecaries in Shadow Fang Keep (World of Warcraft)

This is for the achievement "Tough Love"

You received a "cologne neutralizer" and a "perfume neutralizer" out of the box the guy gives you at the beginning.

The trio uses cologne and perfume to damage you. They spray them and it places colored circles on the ground, the circles dmg anyone near the circles every second dealing a lot of damage.

When there is a green circle on the ground, that is cologne damage, make sure you have the cologne nuetralizer on. It will damage you continuously each second that you do not have it on. and are near these color circles.

The purple circle is perfume. Use the perfume neutralizer when there are purple circles around to avoid perfume damage.

Other than using the neutralizers correctly, this fight is tank and spank. The adds have very low health so anyone can kill them in 1 shot.

Your best bet is to use a neutralizer and stand on the color you are immune to.
