Introduction from the next handbook I’m writing (raw and unedited)
Before you step out the door, so to speak, you really do want to have some basic knowledge of first aid, if your stepping out into the wilder parts, you really should have an advanced knowledge of first aid and be up to date on the current training and procedures available.
Carrying a decent pocket or small first aid kit is most advised, and like any other kit you carry, you should be familiar with its contents and confident in its use.
Addressing any injuries as soon as possible is most important. Taking care not to injure your self is paramount!
Any cuts, scrapes, splinters etc, should be cleaned out with plenty of fresh water if possible, sea water in cold climates, where micro toxins are at a low density will clean and also aid healing, but in warmer climates where algae blooms etc, may be present in high densities, the sea water may actually infect and cause the cuts etc to degrade, boiling any water to sterilise it, before cleaning a wound, is advised.
Seaweed plasters and poultices work effectively and the iodine amongst other healing properties, heals the wound and seals it from secondary infection.
Seaweed as it dries shrinks to a third (roughly) of its size, so a wrapped frond of seaweed around the finger say, will actually, as it dries tighten and hold fast, the original sticking plaster maybe?
True Dulse (the flat red one) is ideal for the job. The kelps are also great for the healing and protecting process, again though, if collected from warm seas, a quick blanch in boing water or over the flames to make them sterile is advised.
Toasted, baked, dried and powdered seaweeds are great to apply to cuts and stem the flow of blood, before healing and making a good barrier from further infection.
