Learning how to treat a wound with homeopathic medicines can be quite straight forward. First, a wound can become infected quite easily. The use of the most appropriate homeopathic medicine will prevent any infection from occurring. It will also clear up an existing infection. The tissue of the wound are damaged and they need the best support to facilitating healing.
The homeopathic medicine Calendula can be effectively used both as an internal healing medicine as well as topically. This is unlike a close relative, Arnica. Arnica must never be applied topically to an open wound as it will cause irritation. To prevent that mistake, it is better not to have any Arnica cream or other topical treatment. Use it internally and it will do just as good a job, better in most cases.
However, the topical use of Calendula will compliment its internal use. If you only have Calendula as an internal medicine, then you can make a solution by putting one pillule in a container of clean, preferably filtered or spring water. This can then be used to wash the wound gently, or to spray into it, if it is too sensitive to clean.
This can also be used to soak the dressing before applying to the wound. Wounds heal better when exposed to the open air, so only cover it with a dressing as long as you need to, sometimes to protect it from further damage or from leaking onto your bedding.
Keep taking the Calendula for several days, to ensure the fastest healing of the wound. Other homeopathic medicines may be needed to complete the healing of damaged nerves and bones. But for a wounded, it's hard to better Calendula.
