There is currently a mysterious bout of Chinese seeds arriving upon unsuspecting US postal customers. A leading theory has something to do with “brushing”  {i.e. a bogus foreign padding of positive reviews on a site like Amazon]

My limited working theory is that they could be an ancient Chinese herbal remedy to fix the common “quality control” failures in toy engines. Add a few seeds to the fuel tank , or squeeze some seeds for lubricating oil that was absent. Jam some seed in the screw holes to keep the screws from backing out.  Could be they are just a generous offer to achieve customer satisfaction?

Anybody got the seeds yet?
