Depends on the manufacturer. Some come as a green syrup with a minty taste. Then there is
Hurry Heal brand CLW potion, which comes in cherry flavored red.
There are also white pastes and red or green ointments. Mint, vanilla, or rose scenting as an added touch.
Last there are CLW ointment impregnated bandages.
Pills and capsules are becoming increasingly popular. Color depends on who makes it. Most are generic brands, as CLWs are not patentable.
Oddly enough, natural vanilla is banned as a CLW potion flavoring. Vanilla flavored CLW potions react strongly with alcohol, producing stupor and in some cases coma and even death. Artificial vanilla is safe to use with CLW potions, but takes on the flavor of burnt meat.
Pastes and ointments come in jars, pills and capsules in plastic bottles. While potions come in glass bottles. There are usually 20 pills or capsules per bottle. 4 to 6 doses in the other forms. Though Costco does sell an economy sized container of its house brand CLW ointment, good for 20 doses. Still pricey, though not as expensive as in a standard D&D world.
Most have a shelf life of 6 months before losing potency. Some store brands become toxic soon after the end of shelf like, and most all take on a nasty flavor.
Uncle Saul's Wound Eraser was pulled from the market because samples past the expiration date were shown to become carcinogenic
Polymorphy Other potions, with the change being random according to body part. (Elephant head and mouse body with some form of carcinoma, that sort of thing.) Uncle Saul's alchemy degree was later found to be from a diploma mill and he is now doing time at the Federal prison at Leavenworth Kansas for fraud, malignant enchanting, causing grevious bodily harm, and homicide. (200 year sentence, which means at his age he'll have another 165 years to serve in the Federal prison system's spirit incarceration facility before he is released.)
