Indian spice to fight lens Fungus...

All of a sudden several of my lenses have got fungus(Pentax f2.8 100mm Macro and Sigma f2.8 180mm Macro). I had not had to fight this for few years; Last time I faced fungus was in 2001, and I spent 175$ for cleaning. At that time, Pentax said that fungus has etched in to glass and replaced the glass.

Today, I found these two articles on Fungus, and one suggested the use of Carom key ingredient of Indian spice. Carom is anti fungal.
This article suggest to have a pack of Silica gel inside lens case and also to observe for change in color of Silica. This is an important piece of information, change in color of Silica means it is saturated with water, time to change.
