I grow and use
Lemon balm
Lavender
Rosemary
Several mints
Thyme
White pine needless
I just made a lotion for friends who are bug magnets using lemon balm, chocolate mint, lavender, rosemary and cinnamon. They tell me it works really well at keeping bogs from biting them.
I also made a lotion for respiratory issues as many of my family and friends have allergies or get sinus infections from the change from cold to hot weather we've been having lately.
That one has white pine needles, thyme and lemon balm in it. Great for sore throats, dripping noses or stuffed up noses.
I make a pain lotion for my husband who just shattered his knee in an accident in March that helps ease the pain and keeps the swelling down for him. Still experimenting with herbs on that one but always use lavender, Rosemary, coriander, and lemon balm in it.
I'm trying to find a lotion that will put him to sleep when he has trouble falling asleep. So far one blend makes him drowsy but does not put him to sleep.
