The two main categories of ingredients are natural and synthetic. Plants, animals and other sources (usually vegetables) are the source of almost every
natural scent. Usually, the source of animal aromatic compounds is the odorous
sack. However, there are a few exceptions, such as ambergris (it derives from a
fatty compound, originally produced by sperm whales). Another exception is
honeycomb, a derivative of beeswax or honey.
A very common source for odorous compounds are plants, because almost every part of them has the potential of providing a source of scent. The aromatic
compounds that are extracted from many plants can derive from the bark, but also
from flowers, leaves and fruits. Resin is another important source of
fragrances, especially conifer resins.
Other natural sources of scents are lichens and seaweeds. Seaweeds, however, are no very used as a source of odorous compounds because they have a low
efficacy. In addiction, their synthetic counterparts are much cheaper to
produce.
The modern perfume industry makes a large use of synthetic sources. The main reasons for this is that synthetic aromas are generally cheaper, and it is easy
to produce them in great quantities. In addictions, they do not change over
time, while natural sources are different depending on the place and time of
collection. Because of that, perfumes from natural sources do not have a
definite recipe, and the production process cannot be automatized.
There are many types of perfumes that are produced using the sources listed above. Their quality (and of course their price) is heavily influenced by the
percent of aromatic compound it contains. The greatest concentration of aromatic
compounds is found in the Eau de Parfum, while Eau de Cologne and Eau de
Toilette contain a bigger quantity of solvent.
In this way, many different perfumes, with an almost infinite range of scents, are produced. There is a classification in order to group perfumes in
general categories. In the traditional classification, there are seven
categories. Two are for fragrances derived from flowers; one is called Single
Floral, if one flower dominates the fragrance, the other is Floral Bouquet, that
is the scent is a mixture of different flower aromas. The other categories are
Ambered (or Oriental), Wood, Leather, Chypre (when the base contains oakmoss,
bergamot, labdanum and patchouli). The last one is Fougere (if the base contains
lavender, coumarin and oakmoss).
There are so many perfumes available in this world, that finding your perfect fragrance is a very long process. It involves many tries, because not only you
have to choose the scent, but you also have to decide which concentration of
aromatic compounds you want.

Number of View :234 Every year, more than a million people in the United States alone suffer from a heart attack, a stroke or cardiac arrest. Studies
have shown that half of those patients will die within an hour after the first
symptoms start showing and on the way to the hospital.
Heart diseases are the end result of many things. These include diabetes, high blood pressure,
smoking, drinking and being overweight. If people do not make some lifestyle
changes, the chances of this happening are much higher as the person gets older.
So how can people prevent the occurrence of heart disease? It's best for the person to undergo a physical exam and discuss certain things with the doctor
to be able to find a solution for each.
If the individual smokes a lot, it is best to quit. Studies have shown that people who stop are able to decrease
the risk almost immediately. It is hard to give up this habit so this should be
done gradually to prevent the person from having withdrawal symptoms.
Having high blood pressure is usually attributed to the kind of food being consumed by the person. It is best then to add some fruits, vegetables and
whole grains to the diet to balance out the oils and fats usually found in meat.
Exercise can also prevent heart diseases. The person doesn't have to enroll in a gym but take an occasional stroll or engage in a sport with friends.
This will help the individual burn excess calories and keep the heart pumping.
Alcohol as mentioned earlier may also contribute to heart disease. Studies have shown that having one or two drinks a day is safe while anything
more than that is dangerous to one's health.
Prevention is key against heart disease especially if there is a medical history of this in the family or
because everyone has the same sort of diet or lifestyle risk. This means that
everyone must sit down and consult with the family physician the changes that
have to be made.
Aside from making certain changes, here are two medications that can also be used to prevent heart disease.
The first is aspirin. Studies have shown that this can make the blood thinner and lessen the
size of blood clots especially during a heart attack. This is usually given to
individuals who had an experience in the past.
People who want are healthy and want to use aspirin must first consult with a doctor since this drug
has not yet been approved for use by the Food and Drug Administration.
