Over the last month or two, a few people have told me that redwood trees secrete some sort of chemical that causes depression. One person added that Native Americans knew this and thought that evil spirits lived in redwood trees.
The people who gave me this info all strike me as good, credible people. They don't know each other (as far as I know); these were three entirely independent conversations.
Yet I find nothing when I google, for example "redwood trees depression."
Anybody out there know anything about this? I'm very curious what the scoop is, if there is one. Thanks!
