Add contents to anywhere between 1 and 150 liters of water.
Fully submerge either wounds or dirty/stained areas of skin or clothing.
If used for healing, wait until wound closes and tingling stops, anywhere from 1 to 60 minutes. Deeper or more severe wounds may require multiple applications.
If used for cleaning, gently swish and rub the area until clean, usually less than 1 minute.
Dispose of water after use. Do not consume. Proven effective on cuts, scrapes, bruises, burns, lacerations, bites, gunshots, frostbite, and local infections.
(All told, when used for the intended purpose, submerging wounds in the treated water will heal up to 2 HP. It's also basically the best thing ever for washing out blood stains.)
