Herbs preparation

In the above two cases, active components were extracted, identified, and tested both pharmacologically and clinically. Other herb preparations, no matter how long they have been used, are still entities that are pharmacologically unknown. Herbal extracts also need better quality monitoring processes, since active components in plants may vary in different varieties and different seasons. If chemical synthesis is...

Essential Oils. Volatile oils from plants are referred to as essential oils. The oils can be obtained through steam distillation, solvent extraction, or separation of the oils from pressed fmit. They consist of oxygenated compounds, terpenes, and sesquiterpenes. The primary flavor components of essential oils are oxygenated compounds. Terpenes contain some flavors but are often removed from the essential oil because they are easily oxidized (causiag off-flavors or odors) and are iasoluble. Essential oils are prepared from fmits, herbs, roots, and spices.

Just like all herbal medicinal preparations, C. sativa should be standardized if extracts or whole plant material are to be used for medicinal purposes. Basic requirements are that all detectable constituents should be known, but also a sustainable quahty control system must be established to achieve the same quahty over all batches. For industrial use of cannabis, standardization could also be necessary to equahze the quality of the product. However, it must be stated that cultivation for this purposes is mostly performed outdoors. Outdoor growth makes standardization of the product difficult due to the environmental changes. For this reason the Dutch medicinal C. sativa is grown under strictly controllable conditions, and therefore indoors, by the company Bedrocan. At this company clones are used for breeding to maintain high standards for quantity and quality. After a strictly selective breeding procedure a plant fine has been estabhshed fulfilhng all criteria as a herb for medicinal use. 

A TLC method was developed for the estimation of nieotinie aeid and nicotinamide (Fignre 10.7) in phatmacentical preparations containing other vitamins, enzymes, herbs, and drugs, etc. [16]. The percentage recoveries for nicotinic acid and nicotinamide were 100.1 + 1.9 and 100.2 1.5, respectively, with this system. Each alcohol extract of samples or standard was pnt on sihca gel TLC plates, which were developed with distilled water. Each silica gel spot visualized under UV lamp was collected and extracted with 0.1 mol/1 HCl. The optical density of each clear extract was measured at 262 run. 

Although there is a common belief that natural herbs do no harm, emergent cases reported that renal failure was associated with chronic use of certain herbal preparations. Another important issue is the interaction between herbs and Western medication. There is a tendency, from that assumption, to neglect the possible side effects induced by the combination of both medications. Drug-drug interactions are listed in the following examples. 

Many types of medications given for the flu make a person feel drowsy. When elderberry preparations are used, reaction and judgment times are not impaired which is why the Israeli Air Force is interested in using elderberry for its pilots. Elderberry medicines are best taken at the first onset of a cold or flu so it s helpful to have some on hand in case illness strikes when all the health food and herb stores are closed. 

Dietary supplements are available in a variety of delivery forms such as capsules, tablets, teas, tinctures, extracts, and bulk herbs. Sixty-eight percent of the herbal products available are in the form of a capsule or tablet. Approximately half of the herbal preparations contain a single herb [3]. An example of a softgel is Saw Palmetto Complex by PhytoPharmica. 

Intravenous preparations of herbs are available in other countries. An intravenous preparation of ginkgo is manufactured in Europe but is not available in the United States. 

This chapter reviews recent findings about the health benefits of phytochemicals present in fruits, vegetables, nuts, seeds, and herbs, including phenolics, carotenoids, sterols, and alkaloids. These phytochemicals are extracted using emerging technologies such as supercritical carbon dioxide (SC-CO2) extraction, PEF, MWE, HPP, UE, and OH. The impact of important parameters related to sample preparation (particle size and moisture content) and extraction process (temperature, pressure, solvent flow rate, extraction time, and the use of a cosolvent) on the efficiency of extraction and on the characteristics of the extracted products is evaluated based on an extensive review of recent literature. The future of extraction of phytochemicals is certainly bright with the... 

My secretary came in to announce that the client in the outer office was impatient. Whatever the matter was — a will to prepare, a divorce, a deed — I handled it before going into the adjoining office to face my brother Herb. He looked up from his desk. Behind tortoise-shell glasses he blinked slowly as he always does to hide his incessant curiosity.
