The works of the ancient Greek physicians record a large number of medicines that were prepared from the natural environment, especially from the plant kingdom and were used successfully in the treatments of many diseases.

In our country, the abundance of medicinal plants that we find in every corner of it, helped in the development of folk medicine and the collection of herbs. The collection of herbs required attention, secrecy and sometimes “magical” procedures to ensure their healing properties. Plants have been used as medicines since prehistoric times.

Angiosperms (flowering plants) were the original source of most herbal medicines. Most medicines in the plant kingdom are very poisonous. But what makes a plant poisonous? It is essentially the alkaloid that makes plants poisonous. Alkaloids are a special class of organic compounds found in nature and contain nitrogen.

The first atomized alkaloid, morphine, was isolated in 1804 from opium (opium poppy, scientific name Papaver somniferum, in Greek Mikon ypnophoros, a species of poppy from which opium is made), of the Papaveraceae family, which we know is very strong.

In Greece, we observe the mystical and medicinal importance of opium. Its mystical character can be seen on various statuettes, seals, or pins, both in Minoan Crete and in other parts of Greece. There is also a reference to Homer in the Odyssey, which outlines opium and its effects.

Later (c. 460 BC), Hippocrates, the “father of medicine”, rejected the “magical” properties of opium, but acknowledged its use as a drug and analgesic.

As a homeopathic remedy, Opium is used in severe drowsiness, narcolepsy, especially if we have a patient who is just lying in bed, “doing nothing”. There is a negative, a lethargic state, there is no pain stimuli, no slight reflexes, no secretions (urine, feces).

The patient says that he is well and happy, he sees the people around, but he feels disoriented and has many hallucinations. In sleep, the mouth is open and the eyes remain half open. This remedy can be used in cases of coma, where opening the eyes can also be difficult.

Every remedy, from the mineral, animal or plant kingdom, was used to treat a certain symptomatology. Centuries later, we see that the same symptoms are extracted from the evidence of homeopathic remedies.

With the evidence of homeopathic medicines, an attempt is made to record the effect of the medicinal substance, by testing it on healthy individuals and these records serve for the compilation of Homeopathic Pharmacology (Materia Medica).
