Cautions

contraindication Eye disorders that involve no stasis or stagnation
pregnancy Avoid in pregnancy
caution Raw bat droppings can harbour Histoplasma, the fungus behind histoplasmosis, and disturbing them releases spores; the risk lies in collecting, drying and handling raw guano rather than in a processed medicine
caution Bats are reservoir hosts for several virus families, so raw bat material and roost sites call for care
caution No published way to authenticate the material exists, so its species, contamination and microbial quality are unverified in commerce
