There’s little effort to conserve the folk knowledge of the bedouin nomadic shepherds. This folk knowledge or oral intangible heritage can very much be helpful and  inspiring for the serious researcher one day in the future. And it seems that the whole body of knowledge about the desert and the plants is going to be lost in the next generation for ever.
The effect of wild food and these high alkaloid plants on Camels and Goats milk has been a part of the human experience since ancient times, yet many people are unaware of the significance that these plants have had in shaping the minds and tribal mood of early cultures. Consciousness & Shepherd’s Wild Food
The numerous alkaloid plants provided not only food for the physical body but food for the so called the light-body, or the dream-body. It provided active chemicals that have played a major role in the early stage of evolution of the human beings and their cultural and spiritual-religious development through the ages. It should that these plants chemistry had subtle effect on the human mind, mood, and consciousness. Understanding this relation along with their active chemical principles may indeed have far-reaching better understanding of the human cultural and spiritual development.

In the photo, you can see the syrian rue seed pods along with incense gum that dropped from the tree, along with few twigs from the Juniper tree that is not seen in the photo along with few other woody shrubs. Such fires were used by nomadic shepherds  for cooking and heating. The combination of such plant chemistry when burned diffidently would have an effect on the shepherd inhaling such fumes when preparing the fire to get warm or cook tea or food. The fumes if inhaled by a smoke pipe would provided chemicals that would have strong effects to the human mind. It is such fires, and such sacred places in the desert with its sacred desert Alkoliodal Plants,  altering the normal functions of the mind and body.

According to Manly P Hall in his book, “The secret teachings of all ages”: “Certain plants, minerals, and animals have been sacred among all the nations of the earth because of their peculiar sensitiveness to the astral fire - a mysterious agency in Nature which the scientific world has contacted through its manifestations of electricity and magnetism. Lodestone and radium in the mineral world and various parasitic growths in the plant kingdom are strangely susceptible to this cosmic electric fire, or universal life force.”
Dried desert Thyme (Bedouin: Za’tar). Its fragrance is particularly strong on the western vallys of wadi Rum.
Smoke from the seeds kills algae, bacteria, intestinal parasites and molds. Smoke from the seeds showed it to have a lifesaving effect on cattle infected with various disease according to the Bedoul tribe.
