Chemical Properties
Ivermectin is a nonhygroscopic compounds, which means that it does not
pick up water. This whitish yellow crystalline powder is non-soluble in
water, but it is soluble in Methanol. Although Ivermectin is highly
toxic to parasites, it has a very low toxicity to humans and animals.

Natural Abundance
Ivermectin is semi-synthetic. It is derived from the strain of bacterium Streptomyces avermectinius
which is commonly found. But seeing as the compound is not naturally
occurring, it cannot have a natural abundance.
