In Sri Lanka, I got really interested in nostril snakes. They are common in Sri Lankan masks, which are used for fun, skits, and to ward off demons and bring good fortune. Apparently the snakes are for protection and power, so don't be snake judgy.
I think this one is Naga rakshna, which is for power, fertility and protection, which I wouldn't always group together. (In real life, there can be nostril worms, but not snakes)
I love the snakeliness very much. I wanted to buy one to ward off the evil spirits who keep breaking our air conditioner, but Barry made ridiculous protestations like they were "ugly" and "creepy", including the smaller ones.
Anyway, the glorious masterpiece below is the Sanni rakshna which embodies all of the 18 diseases. The fun friends include being possessed by demons, fire fever, snakebite and leprosy. They allow you to confront the disease and scare it away, from how I understood it. Seems worth a try alongside the recommendations of a medical professional.
You can see that going down here, I guess, although the masks are kinda missing. I should have asked more questions.
The less fancy masks are used for storytelling and performances.
Which still seem like they could be scary as fark for children.
Sweet dreams!
