There are many herbs which aid the body’s healing processes. Some of these are multi-purpose and others specific. All can be mixed into sachets which, when carried, help the body’s healing powers. Some are used in incense form, others added to the bath.
Having said this, when a serious condition or severe symptoms occur, obtain medical attention immediately. Herb magic—as with all magic—must be backed up with appropriate and timely actions in the physical world. For example, you cannot perform a spell to pass a test and expect to do so without studying.
Similarly, don’t expect magic to heal you unless at the same time you take care of yourself physically. This means getting medical help when needed.
