i made up some potions that where in an alchemist's lab that my players bottled up: 2 yellow - Stimulates its drinker’s natural healing ability. The target regains 2d8 + 7 hit points. After an hour the creature becomes partially transparent and takes 1d6 psychic damage after a short or long rest. The transparent effect lasts 1d4 days.
1 orange - Upon drinking, all negative conditions are removed, health is restored to full, and any injuries are instantly healed. After 1 minute, the creature becomes unconscious for 1d4 hours.
