Truly one of the wonders of nature, many members of the Cordyceps family of fungi reproduce by infecting - and in some cases - controlling the behaviour of host insects.

 

Check out the great YouTube video from David Attenborough and the BBC.

Fortunately it is not really as scary as that. YCT uses caterpillar Cordyceps, which has records of use in oriental medicine date back thousands of years.

All the ingredients are farmed in a controlled environment with strict quality control.

YCT's caterpillar fungus products are available in isolation or in combination with other Chinese medicine ingredients.
