Brews
Griss has a multi generational collection of medicinal recipes that work on dragons and to everyone’s surprise with a slight adjustment for weight, they also work on humans. One of the reasons that holds true, at least in my writer’s imagination is because they have similar systems; respiratory, muscular, vascular, digestive. They bleed red blood and while their genitals are recessed among their males and only emerge during arousal, they are similar in function. That also allows both species to use the same contraceptive brews.
