Joly takes an innocent-until-proven-guilty approach with his treatments, so he’s super into studying traditional treatments, from acupuncture to meditation. He even has his own herbal garden, so he can try out traditional herbal teas and medications. A few of his teas and medications are of his own concoction because even if the traditional formulations don’t work, perhaps new formulations will.
(Joly prepares a specific tea formulation for Combeferre every week, because Combeferre asks for one and Combeferre does stay awake an inordinate amount of hours to study all that he does. Joly worries.)
