Oregano water

Aromatic waters or hydrosols are aqueous distillates free of floating essential oil. They are obtained during distillation of essential oils and consist of the clear aqueous part of the distillate after the removal of essential oil. Aromatic waters such as rosewater can be used for culinary and cosmetics purposes and are sprinkled in religious ceremonies. In Turkey, oregano water is internally consumed as a popular drink to regulate the astrointestinal system and for indigestion, heartburn, stomachache, colics, and cancer as well as to reduce blood sugar, cholesterol, and blood pressure. Carvacrol has been shown to be responsible for the claimed effects (19,44,45). 

Hydrosols (distilled waters of aromatic herbs) contain approximately 0.1% of dissolved oil in water and are safer than oils for internal use. In Turkey, oregano water (distilled water of oregano) has become a popular health drink in recent... 

PCP is available in the form of tablets, capsules, liquid, and powder. In its base form, PCP is a white crystalline powder that is snorted, pressed into tablets, or mixed together with water or alcohol. More commonly, it is sprayed in its liquid form on leafy material such as oregano, mint, or marijuana, and sold to end users in the form of joints to be smoked. 

You can repeat this experiment with other things that float on water. You can try chili powder, cinnamon, oregano leaves, or parsley. The spreading soap will push anything on the surface to the side of the plate. 

Most contain carvacrol and thymol in varying amounts. Dried oregano will contain 0.2 to 0.4% of a yellowish volatile oil with thymol and carvacrol in varying amounts. The phenolic content may be 50 to 65%. Carvacrol is found in the oil of oregano, thyme, marjoram, and summer savory. It is practically insoluble in water. It is used as a disinfectant and in organic synthesis. Therapeutically, it is used as an anti-infective and anthelmintic.

PFE has been used in the analysis of biological samples for two main purposes, namely to determine contaminants in food and animal tissues and to extract target species from animal and plant tissues. In the last case, dynamic-PFE has been used widely for isolation of edible essential oils from plants such as fennel, marjoram, laurel, rosemary, oregano, and eucalyptus, using water as the extractant.
