Is there any way to thicken a cold sauce???

I've made a garlic/herb/mint sauce using natural yoghurt as the base, but its too runny. Is there anyway to thicken it by stirring something in without the need to cook it. Is it ok to use cornflour without cooking it?

Thanx

I'd be wary of gelatin because of lumps (leaf gelatin might be OK) and cornflour needs to be cooked out.

Some shop bought mayonaise might work and shouldn't ruin the flavour if used carefully.

arrowroot perhaps?

Thanx for the replies,

After reading up, what I need is something called Guar Gum, that most commercial sauce makers use to thicken things. Its supposed to be a sort of emulsifier which can supposedly be purchased for home use, but I can't seem to find it anywhere, lol.
