I kept the card that was attached to my bottle of Superthrive. The address
is
VITAMIN INSTITUTE
5411 Satsuma Ave
North Hollywood, CA 91601
It is said to contain "vitamins, hormones, bio-usables. ...saves plants from
waiting to make many life-process complexes, carbon-hydrogen-oxygen groups."
No mention of snake oil.....but its ads still look like somthing out of the
1940s.
