Bazi Plague
A deadly, rapidly- spreading disease with no known cure; its symptoms include pustules which  appear all over the body, and a yellowing of the whites of the eyes. Also called pox, it is believed to be transmitted by lice.  Survivors of the pox convey an immunity to their offspring.  Slaves diagnosed with pox are usually killed as a method of containing the disease. "We are going to test you for pox," he said. The girl groaned. It was my hope that none on board the
Clouds of Telnus had carried the pox. It is transmitted by the bites of lice. The pox had appeared in
Bazi some four years ago. The port had been closed for two years by the merchants. Ithad burned
itself out moving south and eastward in some eighteen months. Oddly neough some were immune to the
pox, and with others it had only a temporary, debilitating effect. With others it was swift, lethal and
horrifying. Those who had survived the pox would presumably live to procreate themselves, on the
whole presumably transmitting their immunity or relative immunity to their offspring. Slaves who
contracted the pox were often summarily slain. It was thought that the slaughter of slaves had its role
to play in the containment of the pox in the vicinity of Bazi.
Slave Girl of Gor, page 325-326

The physician would check the health of the crew and slaves.  Plague, some years ago, had broken out in Bazi, to the north, which port had then been closed by the merchants for two years.  In some eighteen months it had burned itself out, moving south and eastward.  Bazi had not yet recoved from the economic blow.  Schendi's merchant council, I supposed, could not be blamed for wishing to exercise due caution that a similar calamity did not befall their own port.

Brak Bush
a shrub whose leaves have a purgative effect when chewed. Branches as a tradition of it are nailed to house doors during the Waiting Hand to discourage the entry of bad luck into the house for the New Year.

  Almost all doors, including that of the House of Cernus, had nailed to then some branches of the Brak Bush, the leaves of which, when chewed, have a purgative effect.  It is thought that the pitch and the branches of Brak Bush discourage the entry of the bad luck into the houses of the citizens.

Breeding wine (Releaser)
A sweet wine which counteracts the effects of slave wine, making a slave girl fertile also called second wine.

She did not need the sit root, of course, for, as she had pointed out, she had had some within the moon, and indeed, the effect of sip root, in the raw state, in most women, is three or four moons. In the concentrated state, as in slave wine, developed by the caste of physicians, the effect is almost indefinite, usually requiring a releaser for its remission, usually administered, to a slave, in what is called the breeding wine, or the "second wine". When this is administered she usually knows that she has been selected for crossing with a handsome male slave.
Blood Brothers of Gor page 319

"The time to worry," said Ina, "is if they decide to make you a breeding slave."
I nodded.
"You must then drink the releaser," she said.
I nodded numbly.
"I have been told it's quite good," she said.
I looked at her with horror.
"Really," she said.
"I am sure it is," I said weakly.
Slave wine makes sense in a slave-holding culture, such as Gor.  The breeding of slaves, like any sort of domestic animals, and particularly valuable ones, is carefully controlled.  As a slave, of course, I could be bred, or crossed, when and however, my master might see fit.  It is the same as with other animals.
Dancer of Gor page 174-175

Capture Scent
A sweetish smelling scent i.e.chloroform.

She opened her eyes, and shook her head. "What is this?" she said.
"Capture scent," I said.
Marauders of Gor pages 115

"Shall I hold again the vial beneath her nose?" I asked.  Soaked in a rag and scarf and held over the nose and mouth of a female, it can render her unconscious in five Ihn.  She squirms wildly for an Ihn or two, and then sluggishly, and then falls limp.  It is sometimes used by tarnsmen; it is often used by slavers.  Anesthetic darts, too, are sometimes used in the taking of females;  the may be flung, or entered into the body by hand; they take effect in about forty Ihn; she awakens often stripped, in a slave kennel.
Marauders of Gor pages 116

Dar-Kosis
Holy disease: an incurable, wasting disease akin to the Earth disease of leprosy. Also known as the 'Sacred Affliction' , so named because it is regarded as being holy to the Priest-Kings and those who are afflicted are considered as consecrated to the Priest-Kings.  The disease is highly contagious, and those who suffer from it are required to wear yellow robes, and constantly sound a wooden clacker to warn of their approach.

"That was the literal translation of Dar-Kosis the Holy disease or, equivalently, the Sacred Affliction. The disease is named that because it is regarded as being holy to the Priest-Kings, and those who suffer from it are regarded as consecrated to the Priest-Kings. Accordingly, it is regarded as heresy to shed their
blood."
Tarnsman of Gor Page 150

the Afflicted, as they are called, have little to fear from their fellow men. Their disease is so highly contagious, so invariably devastating in its effect, and so feared on the planet that even the boldest of outlaws gives them a wide berth. Accordingly, the Afflicted enjoy a large amount of freedom of movement on Gor. They are, of course, warned to stay away from the habitations of men, and, if they approach too closely, they are sometimes stoned. Oddly enough, caustically, stoning the Afflicted is not regarded as a violation of the Priest-Kings’ supposed injunction against shedding their blood."
Tarnsman of Gor Page 150-151

"As an act of charity, Initiates have arranged at various places Dar-Kosis Pits where the Afflicted may voluntarily imprison themselves, to be fed with food hurled downward from the backs of passing tarns. Once in a Dar-Kosis Pit, the Afflicted are not allowed to depart."
Tarnsman of Gor Page 151

Frobicain
a sedative injection used during Voyages of Acquisition to render a captured barbarian unconscious.

"They seem very quiet," I observed.'We permit them," said Flaminius, designing to offer a bit of explanation, "five Ahn of varied responses, depending on when they recover from the frobicain injection. Mostly this takes the form of hysterical weeping, threats, demands for explanation, screaming and such. They will also be allowed to express their distress for certain periods at stated times in the future."
Assassin of Gor  page 126

Gieron
A drug, an allergen, which causes a yellowing of the whites of the eyes; in combination with sajel, it reproduces the symptoms of the Bazi plague.

"My pursuit of you was foiled," I said, "by the results of the drug you placed in my paga."
"The drug," said Shaba, "was a simple combination of sajel, a simple pustulant, and gieron, an unusual allergen. Mixed they produce a facsimile of the superficial symptoms of Bazi plague."
"I could have been killed," I said, "by the mob."
I did not think many would care to approach you," said Shaba.
"It was not your intention then that I be killed?" I asked.
"Certainly not," said Shaba. "if that was all that was desired, kanda might have been
introduced into your drink as easily as sajel and gieron"
Explorers of Gor page 154

Kanda
a shrub of the Gorean desert, a lethal poison can be extracted from its roots, while chewing
the leaves has an addictive narcotic effect

"The roots of the kanda plant, which grows largely in desert regions on Gor, are extremely toxic, but, surprisingly, the rolled leaves of this plant, which are relatively innocuous, are formed into strings and, chewed or sucked, are much favored by many Goreans, particularly in the southern hemisphere, where leaf is more abundant."
Nomads of Gor, page 43

Pox

"We are going to test you for pox," he said.  The girl groaned.  It was my hope that none on board the Clouds of Telnus had carried the pox.  It is transmitted by the bites of lice.  The pox appeared in Bazi some four years ago.  The port had been closed for two years by the merchants.  It had burned itself out moving south and eastward in some eighteen months.  Oddly enough some were immune to the pox, and with others it had only a temporary, debilitating effect.  With others it was swift, lethal and horrifing.  Those who had survived the pox would presumably live to procreate themselves, on the whole presumably transmitting their immunity or relative immunity to their offspring.  Slaves who contracted the pox were often summarily slain.  It was thought that in the slaughter of slaves had had it's role to play in the containment of the pox in the vicinity of Bazi.

Sajel
A drug which causes harmless pustules to erupt on the body; in combination with gieron, it  reproduces the symptoms of the Bazi plague.

"My pursuit of you was foiled," I said, "by the results of the drug you placed in my paga."
"The drug," said Shaba, "was a simple combination of sajel, a simple pustulant, and gieron, an unusual allergen. Mixed they produce a facsimile of the superficial symptoms of Bazi plague."

Sip Root
A bitter root whose extract is the active ingredient in slave  wine.

I held the object before her. She regarded it with dismay.
"I have already chewed sip root within the moon," she said.
"Open your mouth," I said.
"Yes,Master," she said.
I then thrust the object into her mouth.
"Chew it well," I said, "and swallow it, bit by bit."
She grimaced, at the barest taste of the object.
"Begin," I told her. she began.
"Not so quickly," I told her, "More slowly. Very slowly.Very, very slowly. Savor it well."
she whimpered in obedience. She did not need the sip root, of course, for, as she had pointed out, she had had some within the moon, and indeed, the effect of sip root, in the raw state, in most women, is three or four moons. In the concentrated state, as in slave wine, developed by the caste of physicians, the effect is almost indefinite, usually requiring a releaser for its remission, usually administered, to a slave, in what is called the breeding wine, or the "second wine". When this is administered she usually knows that she has been selected for crossing with a handsome male slave.

Slave Wine & references to it's releaser (also see Breeding Wine)
A black, bitter beverage that acts as a contraceptive; its effect is instantaneous and lasts for well over a month; can be counter-acted with a another, sweet-tasting beverage called Breeding Wine.

"Have you had your slave wine?" asked Ina.
"Yes," I said. This is not really a wine, or an alcoholic beverage.  It's called "slave wine," I think, for the amusement of the masters.  It's extremely bitter.  One draught of the substance is reputed to last until the administration of an appropriate "releaser."  In spite of this belief, however, or perhaps in deference to tradition, lingering from earlier times, in which, it seems, less reliable, "slave wines" were available, does of this foul stuff are usually administered to female slaves at regular intervals, usually one or twice a year.  Some girls, rather cynical ones, I suspect, speculate that the masters give it to them more often then necessary just because they enjoy watching them down the terrible stuff.  This is unlikely, however.  There are cheaper and more easily available ingredients for such a mode of discipline then slave wine.
Dancer of Gor, page 174

On Slave Wine "Need I drink that?" I asked, apprehensively. "Unless you have had slave wine," he said, "I have no intention of taking you through the streets clad as you are. Suppose you are raped." I put the flask, which he had opened, to my lips. "It is bitter!" I said, touching my lips to it. "It is the standard concentration, and dosage," he said, "plus a little more, for assurance. Its effect is indefinite, but is normally renewed annually, primarily for symbolic purposes."
Kajira of GOR Page 130

Stabilization Serums
A series of medical injections which, among other things, retards the aging process; a discovery of the caste of Physicians

The Stabilization Serums, which are requarded as the right of all human beings, be they civilized or barbarian, friend or enemy, are administered in a series of injections, and the effect is, incredibly, an eventual, gradual transformation of certain genetic structures, resulting in indefinite cell replacement without the pattern of deterioration.  These genetic alterations, moreover are commonly capable of being transmitted.  For example, thought I received the series of injections when I first came to Gor many years ago I had been told by the Physicians that they might, in my case, have been unnecessary, for I was the child of parents who, though of Earth, had been of Gor, and had received the serums.  But different human beings respond differently to the Stabilizations Serums, and the Serums are more effective with some then with others.  With some the effect lasts indefinitely, with others it wears off after but a few hundred years, with some the effect does not occur at all, with others, tragically, the effect is not to stabilize the pattern but to hasten the degeneration.  The odds, however, are in the favor of the recipent, and there are few Goreans who, if it seems they need the Serum's, do not avail themselves of them.
Assassin of Gor, page 30 and 31

I had spent eight days in the slave pens, waiting the night of the sale. I had been examined medically, in detail, and had administered to me, while I lay bound, helplessly, a series of painful shots, the purpose of which I did not understand. They were called the stabilization serums. We were also kept under harsh discipline, close confinement and given slave training". I well recalled the lesson which was constantly enforced upon us:
"The master is all. Please him fully."
"What is the meaning of the stabilization serums?" I had asked Sucha.
She had kissed me. "They will keep you much as you are," she said, "young and beautiful."
I had looked at her, startled.
"The masters, and the free, of course, if there is need of it, you must understand, are also afforded serums of stabilization," she said adding, smiling, "though they are administered to them I suppose, with somewhat more respect than they are to a slave
"If there is need of it?" I asked.
"Yes " she said
"Do some not require the serum'?" I asked.
"Some, said Sucha, "but these individuals are rare, and are the offspring of individuals who have had the serums."
"Why is this?" I asked.
"I do not know," said Sucha "Men differ."
The matter, I supposed, was a function of genetic subtleties, and the nature of differeng gametes. The serums of stabilization effected, it seemed, the genetic codes, perhaps altering or neutralizing certain messages of deterioration, providing, I supposed, processes in which an exchange of materials could take place while tissue and cell patterns remained relatively constant. Ageing was a physical process and, as such, was susceptible to alteration by physical means. All physical processes are theoretically, reversible. Entropy itself is presumably a moment in a cosmic rhythm.
The physicians of Gor, it seemed, had addressed themselves to the conquest conquest of what had hitherto been a universal disease called on Gor the drying and withering disease, called on Earth, ageing. Generations, of intensive research and experimentation had taken place. At last a few physicians drawing upon the accumulated data of hundreds of investigators, had achieved the breakthrough, devising the first primitive stabilization serums, later to be developed and exquisitely refined.
I had stood in the rage startled, trembling. "Why are serums of such value given to
slaves?" I asked.
"Are they of such value?" she asked "Yes," she said, 'I suppose so."
She took them for granted, much as the humans of Earth might take for granted routine inoculations. She was unfamiliar with ageing. The alternative to the serums was not truly clear to her.
"Why should slaves not be given the serums?" she asked. "Do the masters not want their slaves healthy and better able to serve them?"
Slave Girl of Gor, page 282

"Ageing," he said, "is a physical process, like any other.  It is, accordingly, accessible to physical influences.  To be sure, it is a subtle and complex process.  It took a thousand years to develop the stabilization serums.  Our physicians reguarded adeing as a disease.  They did not reguard it as, say, a curse, or a punishment, or something inalterable or inexplicable, say, as some sort of destines, implacable fatality.  No they reguarded it as a physical problem, susceptible to physical approaches.  Some five hundred years ago, they developed the first stabilization serums.

Tassa Powder
A reddish powder, usually mixed with red wine, which renders the consumer unconscious.
Guardsman of Gor, page 113
Players of Gor, page 293

I had been forced, sitting in the courtyard, my head back and nose held to swallow a draft of water, into which a reddish powder had been mixed.  I had shortly thereafter lost consciousness.

(then later on explaining what the reddish powder was)
"You have recovered more quickly then I had anticipated from the Tassa powder," she said.
