Disadvantages Of Medicinal Plants

1.3.2 To determine the physicochemical properties of essential oil extracted from calamondin (Citrus microcarpa) peels.

An example of those are carnosic acid, rosmarinic acid and caffeic acid, possessing strong antioxidant, radical-scavenging, and antibacterial activities. The majority of the phenolic acids in Sage species are derivatives of caffeic acid which is the building block of a variety of plant metabolites. Caffeic acid plays a central role in the biochemistry of the Lamiaceae plants, and occurs mainly in a dimer form as rosmarinic acid. Carnosic acid and rosmarinic acid, which are present at high concentrations in the extract of Sage plants, have shown strong antioxidant properties. Ursolic acid, also a component of sage, has strong anti-inflammatory properties, and in sage preparations, it is considered as a quality control measurement for the anti-inflammatory effects of different

The next day an orange goopy textured product resulted. The extracts were then dried and combined with anhydrous sodium sulfate, then evaporated with dry air under the hood in a warm water bath. The liquid was cooled and had an initial weighing of 0.5887g. It was reweighed several minutes later with a final

The use of natural products as medicine has initiated the isolation of active compounds. The first commercial pure natural product introduced for therapeutic use is generally considered to be

Licorice root is used worldwide as a natural sweetener, as well as a flavoring agent. The main composition of plant Flavonoids and Isoflavonoids act as inhibition platelet aggregation, and anticancer, antioxidant (20). Aly et al.,2005(21) indicate that liqurice have potent anti-inflammatory reduction edema about 78.3 while diclofen about 73.9% also have anti-ulcerogenic activity associated with a reduced acid output and an increased mucin secretion, an increase in prostaglandin E2 release and a decrease in leukotrienes (22). Many volatile oil and vitamins such as B1,B2,B3,B6,C,E, Biotin, Foli acid, Pantothenic acid act as expectorant, laxative, liquiritin act as antitussive (23). Also contain Coumarins Herniarin and umbelliferone (24).moreover plant used for treatment of asthma , chronic fatigue, hormonal disturbance , antiviral, antibacterial , hepatoprotective, anti-oxidant , antiulcer, ant mutagenic, Hypothermic antioxidant, anti-inflammatory, relieve pain , expectorant, hypoglycemia,

During the last decade, St. John's wort (Hypericum perforatum) has gained popularity as an alternative treatment for depression and a natural remedy for reducing inflammation due to its especial chemical composition(1, 2). H. perforatum is a perennial herb of the Hypericaceae family native to parts of Europe and Asia (middle-east and other parts) and also has spread worldwide, including temperate regions of India, China, Africa, and some parts of the United States and is distinguished by its golden yellow calycles(1) . In addition, when flower buds are crushed, a reddish liquid would be exposed. This reddish liquid contains numerous compounds with biological activity such as phloroglucinols hyperforin, adhyperforin, the naphthodianthrones hypericin and pseudohypericin, the flavonoids hyperoside, quercetin, rutin, quercitrin and isoquercitrin, and the dimeric flavonoids amentoflavone(3). Oily Hypericum preparations have been used for centuries as a medicinal plant to treat burns, wounds, alcoholism, dermatitis, neuralgia and myalgia beside its antidepressant, antiviral, and antibacterial effects(4-7). Nowadays,

Most people are familiar with medicines and medications or have been on one or more themselves. Did you know that there are many other alternatives to achieving health without pumping your body with harsh chemicals and risking dangerous side effects? What if I tell you there are natural remedies that have been used successfully for thousands of years to cure, heal, and maintain health! I have always been interested in a more natural approach to wellness, but I actually learned better options to maintain a sound mind and body when I began working at a health and wellness center. I hope to share the history, processes, and excellent benefits of essential oils so that you can choose a natural approach to your health if you wish as well!

“Present in the leaves are severl phenolic compounds such as protocatechuic acid, ferulic acid, quercetin and guavin B” [10], “quercetin, ascorbic acid, gallic acid and caffeic acid Others include Terpenoids and flavonoids such as Oleanolic acid Nerolidiol, β-sitosterol, ursolic, crategolic and guayavolic acids as well as essential oil including α-pinene, β-pinene, limonene, menthol, terpenyl acetate, isopropyl alcohol, longicyclene, caryophyllene, β-bisabolene, cineol, caryophyllene oxide, β-copanene, farnesene, humulene, selinene, cardinene and curcumene” [9].

The dried powdered stems of E. calophrys (3 kg, 230-270 mesh) were macerated with methanol (MeOH, 3 x 7.5 L, 24 h each time) at room temperature and yielded a dried methanol extract as dark green gum (150 g). This extract was further fractionated using a silica gel VLC (10 x 5 cm, 150 g), eluted with n-hexane–ethyl acetate (from 8:2 to 0:10) followed by pure MeOH, and gave 5 main fractions (F1-F5) with weight of 1.1, 5.0, 10.3, 10.2, and 58.4 g, respectively. Main fraction F2 was re-fractionated using a silica gel VLC (5 x 5 cm, 50 g) and gradiently eluted with n-hexane–ethyl acetate (from 7:3 to 0:10) and MeOH as mobile phases, to yield subfractions F21 (0.2 g), F22 (1.0 g), F23 (0.8 g), and F24 (1.2 g). Subfraction F23 was chromatographed using a silica gel RC with chloroform–MeOH (95:5) and pure MeOH as mobile phases, to produce pure compound 1 (0.2 g). Furthermore, the main fraction F3 was subjected to a

The solvent usually has a lower boiling point than the essential oil, so it is boiled off leaving the essential oil behind. (Keville, 2007, para. 6)

It would take several books to cover all the information there is on essential oils. Don't let this page be your last stop on this subject. Of course you can always find more information at your essential oil suppliers. In Aromatherapy essential oils are often described by their "note". There are three categories of classification, top note, middle note and base note. These terms relate to the rate they evaporate meaning, how long the fragrance will last.

It is the oldest and still extensively used in many parts of the world today. Herbal medicines played an important role in maintaining the human health for thousands of years, and have gained growing popularity and extensive usage in the world over the last decades5. Using plants as medicine provides remarkable advantages for treating many conditions5. Different parts of the plant provides certain therapeutic effects therefore, it can be used to treat many different diseases. They are usually sold as tablets, capsules, powders, teas, or even as dried plants6. Pharmaceutical drugs contain specific active constituents, while herbal medicines contain relatively unprocessed mixtures of phytochemical constituents and their holistic efficacy is usually produced by the unresolved integrative effects between the constituents

Methanolic extraction and hot water extraction were performed in duplicate for all tea samples. To prepare the methanolic extraction, 25 ml of methanol was added to 1 g of tea sample. For complete extraction, ultrasonication was performed for 15 minutes at room temperature. Following ultrasonication, tea samples were filtered through 0.45 µm cellulose acetate membrane filter (VMR International) and stored at -20oC until analyses. In addition to the methanolic extracts, hot water extraction was performed to mimic the homemade tea preparation. To prepare the hot water extraction, 1 g of tea sample was dissolved in 25 ml freshly boiled water and incubated for 7 minutes in a covered glass bottle and stirred three times with

Research has long held the traditional belief of the therapeutic benefits of particular plants although terminology has changed quite a bit. For example, basil was described as an herb that "taketh away sorrow" and as "good for the heart" whereas modern terminology now describes it as an antidepressant and/or a prophylactic. It is also important to note that essential oils can cover a wide range of activities, for instance one oil can be a stimulate for one particular body system while being a sedative for

Herbal medicines are great alternative for commercially manufactured medicines available in the market. The major reason why herbal medicine differ from modern medicine is because they are produced with 100% natural content. Therefore the plant extract has all the medicinal values that are as effective as modern medicine. Commercially prepared drugs show results quickly but have numerous side effects. However herbal medicines don’t show any side
