Harvesting and processing

Harvest
July-September, 3-4 years after mycelium inoculation on pine logs

Sclerotum excavated by hand from the ground around pine logs. The soil is cleaned, sorted by size and processed according to type: Whole Fu Ling (茯苓), Fu Ling Pian (slices), Fu Shen (with inner wood), Fu Ling Pi (bark).

Raw (茯苓 Fú Líng)

Fresh sclerot buried in covered piles for 3-5 days to 'sweat' and soften, then peeled, cut into slices or cubes and dried slowly in the shade. Rapid drying in the sun produces cracks.

Bark (茯苓皮 Fú Líng Pí)

Dark outer bark separated during peeling, washed and dried. It has a more strongly diuretic action than the interior meat.

With pine root (茯神 Fú Shén)

Part of the sclerot surrounding the central pine root. It is separated and processed the same as the main meat. It has a more pronounced action on the Shen.
