Free Women, and even some Turian slave girls, went to and fro, bringing water and, here and there, where there was point in it, binding wounds."
-Nomads of Gor p263

(Speaking of the land surrounding the Ua River)
The river and forests teemed with life. Fibrous, medicinal, and timber resources alone seemed inexhaustible. A new world, untrapped, beautiful, dangerous, was opened by the river. I think it would be impossible to overestimate its importance."
-Explorers of Gor p383

A physician entered the booth with his kit slung over the shoulder of his green robes. When the physician had finished the cleansing, chemical sterilization and dressing of the wounds [dagger stab wounds] he left. The scribe paid the physician a tarsk bit."

(Samos's instructions after reading a message marked on a slave girls head with a tattoo)
"Take the girl to the pens," said Samos to the guards. "With needles remove the message from her scalp."

(Gorean Physician's recommendation to Free Women that consult them about frigidity)
A familiar bit of advice given by bold Gorean Physicians to Free Women who consult them about their frigidity is, to their scandal, Learn slave
dance. Another bit of advice, usually given to a Free Woman being ushered out of his office by a Physician impatient with her imaginary ailments is, Become a slave.

Public Health Section

(The storage of meat)
In another area boiled meat hung on ropes. Insects swarmed about it.

(The decay of food)
Further, of course, a body in the Tahari decomposes with great slowness. The flesh of a desert tabuk which dies in the desert, perhaps seperated from its heard, and unable to find water, if undisturbed by salivary juices of predators, remains edible for several days.
-Tribesmen of Gor pg. 117

Leech plant
A hemovorous plant that fastens two hollow, fang like thorns into its victim, through which it can suck the blood that nourishes it. It strikes like a cobra.  You can hear the popping, sucking sound of the bladderlike seed pods of the plant as they expand and contract. They are usually cleared from the sides of the road. They are primarily dangerous only to children and small animals. But, an unwise person who chooses to sleep in an unknown wilderness area might also succumb to their dangers.

(Tarl Cabot speaking of the state of technology on Gor)
Be that as it may, the Priest Kings have limited man severely on this planet in many respects, notably in weaponry, communication, and transportation. On the other hand, the brilliance which men might have turned to destructive channels was then diverted, almost of necessity, to other fields, most notably medicine.
-Assassin of Gor pg 30

(Information on the operating room of the Priest Kings where they had a Human member of the Caste of Physicians perform neurosurgery)
I looked about the room, turning my head painfully, and saw that the room was some sort of operating chamber, filled with instrumentation, with racks of delicate tongs and knives. In one corner there was a large drumlike machine with a pressurized door which might have been a sterilizer.
-Priest Kings of Gor pg. 253

(Discussion of the capabilities of Physicians in doing the neurosurgery to create a "Implanted One "for Priest Kings)
"Who has done this?" I asked. 
"I," said Parp. "The operation is not as difficult as you might expect and I have performed it many times."
"He is a member of the Caste of Physicians," said Kusk, "and his manual dexterity is superior even to that of Priest Kings."
-Priest Kings of Gor pg. 254

(Discussion of " Implanted Ones", agents of the Priest Kings that have had neurosurgery performed on them to allow the Priest Kings to control their will and to be able to see through their eyes)
"You are seeing through the eyes of an Implanted One," said Sarm. 
I gasped. Sarm's antennae curled. "Yes," he said, "the pupil of his eyes have been replaced with lenses and a control net and transmitting device have been fused with his brian tissue. He himself is now unconscious for the control net is activated. Later we will allow him to rest, and he will see and hear and think again for himself."
[Skipping a line] "Can he disobey you?" I asked. 
"Sometimes there is a struggle to resist the net or regain consciousness," said Sarm. 
"Could a man so resist you that he could throw off the power of the net?"
"I doubt it," said Sarm, "unless the net were faulty."
"If it could be done," I said, "what would you do?"
"It is a simple matter," said Sarm, "to overload the net's power capacity."
"You would kill the man?"
"It is only a human," said Sarm."
