They give nearly half the Toxicity of a HP potion, meaning despite healing you less they're more efficient and economic (not exactly more economic, HP Potion has no moss plants but 1 more scroom) to drink rather than HP potions if you're orderly. Once you reach 10 Orderly it will stop giving orderly and stop dealing damage and instead heal you by 25 HP.
If you are lower than 10 Orderly it will deal 10 damage when consumed and give you 2 Orderly.
