ClavanoAbstract:Plants play a vital role in the production of most medicine and drugs. Extracts of different plants are known to have therapeutic effects. Synthetics and pharmaceuticals are based on natural compounds first found on plants‚ bacteria and fungi. About 40% of all prescribed drugs are derived from natural substances composed of scientifically developed synthetic drugs (Valencia‚ 2008).The skin is made up of thousands of tissues and its outer covering (epidermis) serves as a protector against germs.

of empiricism begins with his distinction between analytic propositions “relationship of ideas‚” which he considers to be a priori and true by definition‚ and synthetic propositions‚ which he considers to be a posteriori (“matters of fact”)‚ and which are opposite of analytic propositions because they’re derived from our senses. Synthetic propositions can pose a problem since they can be untrue. An example is the sun. We can say that it will rise tomorrow—which is likely to happen because we have

In medical conditions blood transfusions are given to patients with low red blood cell counts due to loss of blood resulting in anemia. Kidney failure can also cause low red blood cell counts.

Synthetic repellents tend to be more effective and/or longer lasting than "natural" repellents.[9][10] In comparative studies‚ IR3535 was as effective or better than DEET in protection against mosquitoes.[11] However‚ some plant-based repellents may provide effective relief as well.[9][10][12] Essential oil repellents can be short-lived in their effectiveness‚ since essential oils can evaporate completely. A test of various insect repellents by an independent consumer organization found that repellents
