Now why would you want to do that? Does the horse have worms in its system? Check with a veterinarian first to see if your horse does have worms, and if it does, give it dewormer (which is a kind of medicine). Your veterinarian will also tell you which dewormer is safe for pregnant mares and which are not.
Routine check-ups, and the vet will give you specific dates for shots to prevent aborting and worming medicine and supplements. The vet can give you more detail, but that is what you do when your horse is pregnant: check-ups and shots and you may alter their diet with special pregnant mare feed/supplements.

Horses give live birth and are pregnant for about 11 months, about 340 days.
I don't think this is something that is a regular equine medicine. Talk to your vet before you give your horse any medicine even if its 'natural'.
