According to the definitions I have adopted, normal potatoes (solanum
tuberosum) are nightshades, and normal potatoes are not fruits. So, not all
nightshades are fruits.

I know a lot of bad things about normal potatoes, but haven't found much
about sweet potatoes. I know that sweet potatoes contain phytoalexins, and
that these substances can cause lung edema. They're hepatoxic to mice.
