I definitely misspoke with this msg. BD508 is a equisetum tea. 
Equisetum tea is made through a 20min decoction and used as is, or is 
diluted homeopathically or is aged for a varying number of days -- or 
any combination of the foregoing. It has a high level of silica. I 
use it as an anti-fungal, but technically it is used to promote the 
life and energy of the soil. I assume this also means the innate 
anti-fungal properties of living soil
