Hello-  I am taking my mare on a trip the end of June and she is likely going to be cycling during the week we are gone.  Prior to her being bred 3 years ago she was always a really easy horse to get along with.  Non herd bound.  However anytime since foaling that she is cycling she is a real winch to ride, herd bound.  Is there an addititive that I can give her so she is easier to get along with this year.  Just a temporary additive.  Something to add to her feed.

MVP Mystic Mare Powder – a raspberry leaf powder supplement. Or see if you vet will give a one time progesterone shot.

All those herbal and natural remedies are not worth the money I'm my opinion. Have your vet give you regumate and deal with it at a hormone level. It works. My mare was absolutely miserable and I tried all the herbs, raspberry leaf junk. She has been a happy happy girl for 3 years now on regumate. 

I just sold a mare that was awful when she was cycling.  She'd just get cranky and heck and she would hip check everything she came close to (fences, trees, horse trailers, whatever).  I put her on the Phytosan CBD about 3 weeks before she left my place and she was cycling hard.  I noticed a much improved attitude within 2 days.  I chatted with the gal I sold her to and she said she went into full blown heat about 4 days after they got her home and she was cranky.  I offered to bring her some of the Phytosan  but she opted to try some CBD drops she had on hand.  said she noticed a difference by the end of the day. 

Not saying its an answer for all the cranky mares but it sure worked for this one. And is relatively cheap to try.
