Gu Syndrome

For over two thousand years, Chinese folklore and medicine recognised a mysterious condition known as Gu syndrome. Unlike any ordinary illness, Gu was believed to arise from a hidden poisonous influence that slowly undermined both body and mind.

The term gu originally referred to venomous insects or worms confined together in a vessel. The ideogrammic compound can be read as 蟲 ('insects') and 皿 ('container' or 'vessel'). Thus the meanig is to be understood as 'poisonous insects raised in a container'. To be clear: Your body is the container or vessel.

Ancient texts claimed that the surviving creature in your body produced a deadly toxin. Victims supposedly developed a bewildering range of symptoms, including chronic fatigue, digestive problems, weight loss, anxiety, depression, strange dreams and even hallucinations.

In traditional Chinese thought, Gu could result from poisoning, parasitic infestation or deliberate sorcery. Because its effects were gradual and often difficult to diagnose, it became a convenient explanation for illnesses that lingered for months or years without an obvious cause.

Modern scientists and historians suggest that descriptions of Gu syndrome may have been inspired by real, but not understood (or misunderstood) medical conditions, particularly chronic parasitic infections that were common in ancient China. Others view it as a cultural attempt to explain mysterious physical and even psychological disorders long before modern medicine could identify their causes.

Traditional treatment (obviously) focused on expelling the hidden pathogen with herbal remedies while at the same time rebuilding the patient's strength. Today, the Gu Syndrome is largely forgotten, although in some misguided Oriental minds it still is a real syndrome that needs to be seriuosly studied[1].
