, which is "the theoretical apogee of summer heat" (Groot 1910 5:851).
Among the Miao on the fifth of the fifth month poisonous animals were put into a pot and allowed to devour each other, and they were called 'gold-silkworms'. The more people were killed by the ku, the richer the kus owner became. In our time the normal term for ku has been 'gold-silkworm'. These animals can make gold. It was typical for the gold-silkworm that people continued to feed this animal in the pot, that humans had to be sacrificed to it, that the animal kept the house clean and worked for its master like a brownie, but that it caused harm to its master if he did not provide proper sacrifices.

"For centuries, the Miao, particularly Miao women", writes Schein (2000:50-51), "have been feared for their mastery of the so-called gu poison, which is said to inflict death from a distance with excruciating slowness."

 description.
a gold caterpillar is a caterpillar with a gold colour, which is fed with silk from Shuh (Szĕ-ch‘wen). Its ordure, put in food or drink, poisons those who take it, causing certain death. It can draw towards a man the possessions of such victims, and thus make him enormously rich. It is extremely difficult to get rid of it, for even water, fire, weapons or swords can do it no harm. Usually the owner for this purpose puts some gold or silver into a basket, places the caterpillar also therein, and throws the basket away in a corner of the street, where someone may pick it up and take it with him. He is then said to have given his gold caterpillar in marriage.

The marquis of [Jin] asked the help of a physician from [Qin], and the earl sent one [He] to see him, who said, "The disease cannot be cured, according to the saying that when women are approached, the chamber disease becomes like insanity. It is not caused by Spirits nor by food; it is that delusion which has destroyed the mind. Your good minister will [also] die; it is not the will of Heaven to preserve him." The marquis said, "May women (then) not be approached?" The physician replied, "Intercourse with them must be regulated." … [Zhao Meng] (further) asked what he meant by ‘insanity’; and (the physician) replied, “I mean that which is produced by the delusion and disorder of excessive sensual indulgence. Look at the character; – it is formed by the characters for a vessel and for insects (蠱 = 皿 and 蟲). It is also used of grain which (molders and) flies away. In the [Yijing], (the symbols of) a woman deluding a young man, (of) wind throwing down (the trees of) a mountain, go by the same name (蠱; ☶ under ☴): all these point to the same signification."

Abdominal wug poisoning


The "poisoning from abdominal wugs" or "abdominal parasites" meaning 2.1 first appears in the (121 CE) Shuowen Jiezi

, namely zhòng 中 "hit (a target); be hit by" and zhòng 蟲 "wug bites".

Cultivated poisonous wug


The second gu meaning "anciently recorded type of artificially-cultured poisonous wug" names the survivor of several venomous creatures enclosed in a container, and transformed into a type of demon or spirit.

The Zhouli ritual text (秋官司寇, tr. Groot 1910 5:826) describes a Shushi 庶氏 official who, "was charged with the duty of exterminating poisonous ku, attacking this with spells and thus exorcising it, as also with the duty of attacking it with efficacious herbs; all persons able to fight ku he was to employ according to their capacities."

Han Dynasty

 "dismemberment
Dismemberment
Dismemberment is the act of cutting, tearing, pulling, wrenching or otherwise removing, the limbs of a living thing. It may be practiced upon human beings as a form of capital punishment, as a result of a traumatic accident, or in connection with murder, suicide, or cannibalism...

 (as tortuous capital punishment)" for criminals convicted of practicing gu-sorcery (see 2.6). Groot (1910 5:840) "Plate VI, Punishment of Cutting Asunder" provides a gruesome illustration. The Zhouli commentary of Zheng Xuan (cf. 2.2, tr. Loewe 1970:195) notes, "Those who dare to poison people with ku or teach others to do it will be publicly executed".

Eberhard (1968:152) says gu, "was also the soul of a dead person whose head had been pitted on a pole. This, too, fits later reports, in so far as the souls of ku victims often are mentioned as servants of the master of ku, if not ku itself served the master."

The Shuowen Jiezi (cf. 2.1 above, tr. Loewe 1970:195) also defines gu as "the spirits of convicted criminals whose heads had been exposed on stakes." This specialized torture term niejie 臬磔 combines nie "target" (which pictures a person's 自 "nose" on a 木 "tree; wooden stand") and jie 磔 "dismemberment". Compare the character for xian 縣 "county; district" that originated as a "place where dismembered criminals were publicly displayed" pictograph of an upside-down 首 "head" hanging on a 系 "rope" tied to a 木 "tree".

Groot (1910 5:828) suggests this meaning of gu, "seems to reveal to us a belief that such a soul, roaming restlessly about because of its corpse being mutilated, must be avenging itself on the living by settling in their intestines in the shape of the same maggots and grubs which gnaw away its decaying head."

Unschuld (1985:49-50) provides historical perspective.
As the legal measures of individual dynasties demonstrate, administrative officials viewed ku as a reality, as late as the nineteenth century. The primary host was considered a criminal; a person guilty of the despicable act of preparing and administering ku poison was executed, occasionally with his entire family, in a gruesome manner. In addition to the obvious desire to punish severely criminal practices that could result in the death of the victim, it is possible that Confucian distaste for the accumulation of material goods, and above all for the resulting social mobility, contributed to this attitude. Indeed, the penalties of the use of ku poison appear to have been more severe than those for other forms of murder.

Heat miasma


The fourth meaning of "evil heat and noxious qi
Qi
In traditional Chinese culture, qi is an active principle forming part of any living thing....

that harms humans" refers to allegedly sickness-causing emanations of tropical miasma
Miasma theory of disease
The miasmatic theory of disease held that diseases such as cholera, chlamydia or the Black Death were caused by a miasma , a noxious form of "bad air". This concept has been supplanted by the germ theory of disease....

. "There was also an ancient belief that ku diseases were induced by some sort of noxious mist or exhalation", writes Schafer (1967:102), "just as it was also believed that certain airs and winds could generate worms".

The Shiji (秦本紀, tr. Groot 1910 5:827) records that in 675 BCE, Duke De 德公 of Qin "suppressed ku at the commencement of the hottest summer-period by means of dogs. According to commentators, these animals were for the purpose butchered and affixed to the four gates of the capital." The Tang Dynasty commentary of Zhang Shoujie 張守節 explains gu as "hot, poisonous, evil, noxious qi that harms people". Displaying gu dogs at city gates reflects meaning 2.3 above.

Besides shapeshifting
Shapeshifting
Shapeshifting is a common theme in mythology and folklore, as well as in science fiction and fantasy. In its broadest sense, it is when a being undergoes a transformation. Commonly the transformation is purposeful, and not a curse or spell...

  gu spirits usually appearing as wugs, classical texts record other animal forms. The (ca. 350 CE) Soushenji "In Search of the Supernatural" (tr. Groot 1910 5:846-847) says,
In P‘o-yang (in the north of the present Kiangsi pr.) one Chao Shen kept canine ku. Once, when he was called on by Ch‘en Ch‘en, six or seven big yellow dogs rushed out at this man, all at once barking at him. And when my paternal uncle, on coming home, had a meal with Chao Sheu’s wife, he spit blood, and was saved from death in the nick of time by a drink prepared from minced stalks of an orange-tree. Ku contains spectral beings or spectres, which change their spectral shapes into those of beings of various kinds, such as dogs or swine, insects or snakes, their victims thus never being able to know what are their real forms. When they are put into operation against people, those whom they hit or touch all perish. Tsiang Shi, the husband of my wife’s sister, had a hired work-man in employ, who fell sick and passed blood. The physician opined that he was stricken by ku, and secretly, without informing him of it, strewed some jang-ho root under his sleeping-mat. The patient then madly exclaimed: "The ku which devours me is ceasing to spread"; and then he cried: "It vanishes little by little." The present generations often make use of jang-ho root to conquer ku, and now and then it has a good effect. Some think it is ‘the efficacious herb’, mentioned in the Cheu li

 ginger" is a renowned antidote to gu poisoning, see below.

The Shanhaijing (南山經, tr. Birrell 2000:4) says the meat of a mythical creature on Mount Greenmound prevents miasmic gu poisoning, "There is an animal on this mountain that looks like a fox, but has nine tails. It makes a noise like a baby. It can devour humans. Whoever eats it will not be affected by malign forces." The commentary of Guo Pu notes this creature's meat will make a person immune to the affects of supernatural qi.

A Tang Dynasty account of Nanyue people (tr. Schafer 1967:102) describes gu miasma:
The majority are diseased, and ku forms in their bloated bellies. There is a vulgar tradition of making ku from a concentration of the hundred kinds of crawling creatures, for the purpose of poisoning men. But probably it is the poisonous crawlers of that hot and humid land which produce it – not just the cruel and baleful nature of the householders beyond the mountain passes.

Wug pest


The "wug pest that eats grain" or "grain that transforms into wugs" meaning 2.5 is seen above in the Zuozhuan explanation of gu as "grain which (molders and) flies away". The (ca. 3rd century BCE) Erya

The Yupian is a circa 543 CE Chinese dictionary edited by Gu Yewang during the Liang Dynasty. It arranges 12,158 character entries under 542 radicals, which differ somewhat from the original 540 in the Shuowen Jiezi...

dictionary defines gu as "longstanding grain that transforms into flying insects".

Groot (1910 5:827) connects this gu "grain pest" meaning with 2.1 "internal parasites" and 2.7 "debauchery".
Thus the term ku also included the use of philtre-maggots by women desirous of exciting the lusts of men and attracting them into debauchery. And, evidently, ku was also used to destroy crops or food-stores, or, as the learned physician expressed it, to make the corn fly away, perhaps in the form of winged insects born therein; indeed, the character for ku is regularly used in literature to denote devastating grubs and insects, including internal parasites of the human body, which exercise a destructive influence like poison.

Gu-sorcery allegedly resulted in a debilitating psychological condition, often involving hallucinations. The Zuozhuan (宣公8, tr. Legge 1872:302) records that in 601 BCE, Xu Ke 胥克 of Jin was discharged from office because he had gu, "an illness which unsettled his mind". The Qing Dynasty

, Schafer (1967:103) says,
the possession of ku poison, like the casting of horoscopes, was cause for official suspicion and action: At that time many tyrannical office holders would orders robbers to bury ku or to leave prophecies in a man's household by night. Then, after the passage of a month, they would secretly confiscate it.

Seduce


This gu meaning 2.7 of "seduce; bewitch; attract; confuse; mislead; bewilder" is evident in the Standard Mandarin words yaogu 妖蠱 "bewitch by seductive charms", gumei 蠱媚 "bewitch/charm by sensual appeal", and guhuo 蠱惑 "confuse by magic; enchant; seduce into wrongdoing". "Ku-poisoning was also associated with demoniac sexual appetite – an idea traceable back to Chou times", says Schafer (1967:103), "This notion evidently had its origins in stories of ambiguous love potions prepared by the aboriginal women of the south.

Many later accounts specify women as gu-magic practitioners. Eberhard (1968:149) explains,
We know that among many aborigines of the south women know how to prepare love charms which were effective even at a distance. In these reports it was almost invariably stated that the love charm had a fatal effect if the man, to whom the charm was directed, did not return to the woman at a specified time.

The Chinese character ku represents a bowl in whose contents worms are breeding. This means decay. It is come about because the gentle indifference in the lower trigram has come together with the rigid inertia of the upper, and the result is stagnation. Since this implies guilt, the conditions embody a demand for removal of the cause. Hence the meaning of the hexagram is not simply "what has been spoiled" but "work on what has been spoiled."

"The Judgment" (tr. Wilhelm 1967:75): "WORK ON WHAT HAS BEEN SPOILED Has supreme success. It furthers one to cross the great water. Before the starting point, three days.

Thus the superior man stirs up the people, And strengthens their spirit."

 (1956:136), "the poison was prepared by placing many toxic insects in a closed vessel and allowing them to remain there until one had eaten all the rest – the toxin was then extracted from the survivor." They note, "It is strange to think that this same method has been successfully employed in our own times for the isolation of strains of soil bacteria capable of attacking the tuberculosis bacillus".

Feng and Shryock (1935:1) describe contemporary practices of gu.
At present, ku is used primarily as a means of acquiring wealth; secondarily as a means of revenge. The method is to place poisonous snakes and insects together in a vessel until there is but one survivor, which is called the ku. The poison secured from this ku is administered to the victim, who becomes sick and dies. The ideas associated with ku vary, but the ku is generally regarded as a spirit, which secures the wealth of the victim for the sorcerer.


Eberhard (1968:152) summarizes gu practices.
The essence of ku, then, was the magic charm that could be prepared out of the surviving animal in the pot. It could be used as a love charm with the object of forcing the loved male to come back to the woman. The ku could be used also as an evil magic with the object of obtaining subservient spirits. This was done by feeding it to unrelated persons who would either spit blood or whose stomachs would swell because of the food they had taken would become alive in their insides, and who would die as a result; similar to the gold-silkworms, their souls had to be servants of the owner of the ku.


The 4th-century Soushenji (cf. 2.4, tr. Feng and Shryock 1935:7) records that gu breeding was a profitable but dangerous profession in the Honan region.
In the province of Yung-yang, there was a family by the name of Liao. For several generations they manufactured ku, becoming rich from it. Later one of the family married, but they kept the secret from the bride. On one occasion, everyone went out except the bride, who was left in charge of the house. Suddenly she noticed a large cauldron in the house, and on opening it, perceived a big snake inside. She poured boiling water into the cauldron and killed the snake. When the rest of the family returned she told them what she had done, to their great alarm. Not long after, the entire family died of the plague.

 elaborately produced gu during the Duanwu Festival (see jincan above).
Ku poison is not found generally among the people (i.e., the Chinese), but is used by the T'ung women. It is said that on the fifth day of the fifth month, they go to a mountain stream and spread new clothes and headgear on the ground, with a bowl of water beside them. The women dance and sing naked, inviting a visit from the King of Medicine (a tutelary spirit). They wait until snakes, lizards, and poisonous insects come to bathe in the bowl. They pour the water out in a shadowy, dark place. Then they gather the fungus which grows there, which they make into a paste. They put this into goose-feather tubes and hide them in their hair. The heat of their bodies causes worms to generate, which resemble newly-hatched silk-worms. Thus ku is produced. It is often concealed in a warm, dark place in the kitchen. The newly made ku is not yet poisonous. It is used as a love potion, administered in food and drink and called "love-medicine." Gradually the ku becomes poisonous. As the poison develops, the woman's body itches until she has poisoned someone. If there is no other opportunity, she will poison even her husband or her sons. But she possesses antidotes. It is believed that those who produce ku themselves become ku after death. The ghosts of those who have died from the poison become their servants.

Gu remedies


Groot (1910 5:861-869) and Eberhard (1968:152-3) detail numerous Chinese antidotes and cures for gu poison-magic. For instance (see 2.4), the Shanhaijing claimed eating a legendary creature's meat would prevent gu and the Soushenji prescribed ranghe 蘘荷 "myoga ginger". Unschuld (1985:47) says
Prescription literature was filled with antidotes. All known Chinese conceptual systems of healing dealt with the ku phenomenon and developed therapeutic strategies that were in accord with their basic principles. The Buddhists recommended prayers and conjurations, thus utilizing the same methods as practitioners of demonic medicine. In pharmaceutical literature, drugs of a plant, animal, or mineral origin were described as effective against ku poisoning. Adherents of homeopathic magic recommended the taking of centipedes, since it was known that centipedes consume worms.

, describes gu diagnosis and cure with ranghe:
A patient hurt by ku gets cutting pains at his heart and belly as if some living thing is gnawing there; sometimes he has a discharge of blood through the mouth or the anus. If he is not forthwith medically treated, it devours his five viscera, which entails his death. To discover whether it is ku or not, let the patient spit into water; if the spittle sinks, it is ku; if it floats, it is not. The recipe for discovering the name of the owner of the ku poison is as follows: take the skin of a drum, burn it, a small piece at a time, pulverize the ashes, and let the patient drink them with water; he will then forthwith mention the name; then bid this owner forthwith to remove the ku, and the patient will recover immediately. Again place some jang-ho leaves secretly under the mattress of the patient; he will then of his own accord immediately mention the name of the owner of the ku


Many gu-poison antidotes are homeopathic, in Western terms. The 8th-century pharmacologist Chen Cangqi (tr. Groot 1910 5:866) explains using venomous creatures both to produce and cure gu-poison.
In general reptiles and insects, which are used to make ku, are cures for ku; therefore, if we know what ku is at work, we may remedy its effects. Against ku of snakes that of centipedes should be used, against ku of centipedes that of frogs, against ku of frogs that of snakes, and so on. Those varieties of ku, having the power of subduing each other, may also have a curative effect .

Needham and Wang (1956:136) say prescribing gu poison as a cure or preventive suggests "that someone had stumbled on an immunisation process", and suggest scorpion-venom and centipede-venom as possible toxins.

Chen (tr. Schafer 1967:102, cf. Groot 1910 5:847) further describes catching and preparing medicine from the shapeshifting gu creature that,
… can conceal its form, and seem to be a ghost or spirit, and make misfortune for men. But after all it is only a reptile ghost. If one of them has bitten a person to death, it will sometimes emerge from one of that man's apertures. Watch and wait to catch it and dry it in the warmth of the sun; then, when someone is afflicted by the ku, burn it to ashes and give him a dose of it. Being akin, to it, the one quite naturally subdues the other.


Besides such homeopathic remedies, Schafer (1967:103) says one could,
give ku derived from particularly venomous creatures to overcome that taken from less lethal creatures. Thus centipede ku could be overcome by frog ku; serpent ku would prevail over frog ku, and so on. There were also soberer, though almost as powerful remedies: asafetida, python bile, civet, and a white substance taken from cock's dung were all used. It is not certain what real maladies these repellent drugs, cured, or seemed to cure. Probably they ranged from the psychosomatic to the virus-born. Many oedematous conditions were called ku, and it has been plausibly suggested that some cases were caused by intestinal parasites (hence the constant worm motif). Others are attributable to fish poisons and arrow poisons concocted by the forest dwellers.


Chinese folklore claims the definitive cure for gu-magic is passing it on to a greedy person. Eberhard (1968:153) says,
The most common way to get rid of the ku (just as of brownies and the golden-silkworm) was to give it away as a present. The actions of a man in Chang-chou (Fukien) are rather uncommon. He found on the ground a package containing three large silver bars wrapped in silk and in addition a ku which looked like a frog (ha-ma); in spite of the danger he took it; at night two large frogs appeared which he cooked and ate; on the next night more than ten smaller frogs appeared which he also ate up; and he continued consuming all frogs that kept appearing until the magic was cast off; in this fashion the man suffered no ill effects from the ku poison.


From descriptions of gu poisoning such involving "swollen abdomen, emaciation, and the presence of worms in the body orifices of the dead or living", Unschuld (1985:48) reasons, "Such symptoms allow a great number of possible explanations and interpretations". He suggests attitudes toward gu were based upon fear of others, envy, and greed. "But the concept of ku is unknown outside of China. Instead, one finds what may be its conceptual equivalent, the "evil eye", present in all "envy societies"."
