OOOHHH! I love this topic! I got lots, but I'll only start with ones I've had personal results with!
These are aromatherapy remedies.
Your kid just cracked his/her head or lip open (my son did both, one week after the other). A cold compress is the first resort while on your way to the hospital. What works even better: A cold compress made up of water, with a few drops of lavender (soothing, reduces bleeding and bruising), chamomile (anti-inflammatory and calming) and tea tree (major anti-infection agent) essential oils. Kept in the fridge and pulled out when needed. Worked like a charm...stopped the bleeding, there was practically no bruising or swelling same day or following, and he stopped crying and calmed down pretty fast! My home is never without this compress blend now.
Feel a cold coming on...sniffles, cough, flu, congestion? 3 drops of tea tree oil rubbed onto the base of each foot at bedtime each night until syptoms are gone (only 1 drop per foot for children). The feet hold the nerve endings to the entire body, and tea tree is famed for killing infection and bacteria. I have used it since I discovered that use for it on both myself and my kids (at least 6 months now) and none of us has had a cold symptom remain after the first day or two, let alone the fact that it never evolved into a full cold/flu.
Mice, small rodent and other similar pests? Mint essential oils such as peppermint or spearmint. Here is what I did when I had a mouse trying to move in to our house: Got a 120 ml. spray bottle, and mixed water, rubbing alcohol (for disinfecting since I have children), spearmint and peppermint oil (about 25-50 drops each to make it good and strong), laid a narrow strip of wax paper around the base of the wall where he was spending most of his time and put drops of the pure essential oils themselves all around it, put some on cotton balls and taped them by his entrances, and sprayed the entire area (under my sink,) with the blend I made every night before bed. I haven't seen him since, and I stopped using it months ago! For some reason rodents and the like don't like the mint oils at all...
Have a headache, muscle aches or tension? Menthol crystals (about a 1/4 tsp.) melted in just a few drops of a carrier oil, blend that half and half with peppermint oil in a 5 ml. dropper bottle. Massage a few drops of the blend into arthritic joints, sore muscles, or the back of your neck or on your temples for headaches (just watch those eyes, this stuff will make your eyes water)!
Ok, that's all I can think of off the top of my head. I'm sure I've got more, but I'll leave it at this for now! Ohhh, I love this topic, thanks for posting it Parasuco!
