Healing...

It's one of those "white witch" staples. We all wish we could do it. And honestly we all can though don't expect some wolverine style super healing, or curing cancer.
All pagans should know a little bit of herbalism.
Tea tree oil and lavender oil to treat grazes, wounds (small) and skin conditions.
Honey and lemon to treat a sore throat.
Ginger and peppermint to treat a bad stomach.
Olive oil to help treat dry skin, especially on the scalp.
Salt to treat wounds and infections in the mouth, also good for soaking wounds anywhere else on the body.
Evening primrose oil to help joints and skin conditions.
Saint Johns wort for easing mild depression.
Lemon oil for killing airborne viruses.
The list is long and helpful and does fall under healing. But remember your doctors are there for a reason, herbalism is for colds not for broken limbs.

There is also the second for of healing. Energy healing. This includes the use of crystals and energy movement as aids to healing. I find these are more effective on emotional and spiritual conditions than physical. Those these can aid in easing light neuralgia.
Information on crystal healing is widely available these days so I'm not going to cover this so much today.  I will go into energy movement though.

Every being produces energy, turning food into heat and movement, it's all energy. Every sound vibration, every step we take, is all the transformation of one sort of energy into another. With enough practice we can start to recognise the flow of these energies. No, this doesn't mean you'll be able to jump tall buildings or push over trucks, but it does mean we can move negative energy out of our bodies.
Bodies are fragile things and can be knocked off balance easily. In energy healing we pull everything back to where it should be. If my arm hurts for no real reason I would identify the energy inside the electrical signals telling my brain my arm should hurt and move it away. It's not easy but it is helpful.
And this can be transferred to any pain or mild melancholy.
You can also put energy into spiritual wounds. Healing the effects of a psychic attack of example.

Well, I hope this has been helpful to you.
