Honey Health Benefits

Honey is composed of two main sugars, levulose and dextrose. These sugars do not need to be broken down by the digestive process, so honey is quickly absorbed into the bloodstream, giving a quick energy boost to the body. It also contains protein, vitamins and minerals, but no cholesterol.
Darker honeys have more nutrients than light ones. Vitamin and mineral content depend on the floral source of the honey. Honey has less than 2% sodium, and as such can be labeled as a sodium-free product by Food & Drug Administration standards.

Honey has been used in many medical applications over the years, but recent studies are now able to prove its beneficial nature in some applications, including as antibacterial topical treatment for burns and ulcers. The reason is because honey has osmotic properties; that is, it tends to withdraw water. Water molecules strongly react with the sugars in honey, leaving little water available for microorganisms. Thus, infection-causing bacteria is literally dehydrated to death by honey.

Enzymatic activities of honey also produce hydrogen peroxide, which generate highly reactive free radicals which kill bacteria, further contributing to its antibacterial properties.

Honey has also been used to successfully store skin grafts for up to twelve weeks. Lab tests have shown that different types of honey have differing antibacterial sensitivities, so research continues to determine which floral sources are most beneficial.

Warning! Honey is not for babies!
Although honey is a natural, healthy food that normally cannot support bacterial life, it's important to note that it can carry C. botulinum spores which may be harmful to the undeveloped immune systems of infants. The old practice of dipping pacifiers into honey to soothe crying babies should be aborted.

Infants up to one year of age should not be fed raw honey, as their immune systems are not yet developed enough to fend off this normally benign strain. Infection can cause a flaccid paralysis weakening the baby's muscles, causing a "floppy" baby. Other symptoms include constipation, lethargy, poor feeding, weak cry, droopy eyelids, expressionless face, drooling or swallowing difficulty, and occasionally, respiratory arrest. By the age of one year, most children develop enough to resist this normally benign strain of botulinum.

Infant botulism is rarely lethal, but is obviously easy to avoid in this instance. Although food manufacturers make extensive use of honey in their products, baby food manufacturers, as a rule, will not include honey in their foods recommended for those babies under one year of age.
It must also be pointed out that infant botulism is not exclusive to the ingestion of honey. The botulism spore can also be found in dust, soil and other uncooked foods that older children and adults are exposed to daily. The risk is minimal. Yet, it is an avoidable risk, and honey should not be fed to infants under the age of twelve months. Don't play the odds.

Health Benefits of Ampalaya (Bittergourd)

Bitter Melon, bitter gourd, ampalaya: This tropical plant which goes by many names, is commonly grown for its edible fruit, which is probably among the most bitter of all vegetables on earth. Bitter gourd predominantly grows in tropical areas, including parts of Asia, East Africa, the Caribbean, and South America, where it is used both as food as well as a medicine. The plant's fruit truly lives up to its name, because it really tastes bitter. Although the seeds, leaves, and vines of this fruit have different uses, the fruit is considered as the safest and most predominantly used part of the plant in traditional herbal medicine.

There has been much research done on the effectiveness of using Momordica Charantia in the treatment of diabetes. It has been shown to increase production of beta cells by the pancreas, thereby improving the body’s ability to produce insulin. It has been recommended by the Department of Health of the Philippines, as one of the best herbal medicines for it’s ability to help with liver problems, Diabetes and HIV.

Ampalaya Is Now Used In Herbal Medicine

Until recently, bitter gourd has been noted to be a potent herbal medicine for a lot of ailments, particularly in treating diabetes. The Philippine variety is known for its more potent anti-diabetic components.

This fruit is composed of a mixture of flavonoids and alkaloids which make the pancreas produce insulin that controls the blood sugar levels in diabetics. Aside from its touted medicinal value, it's also a very wonderful source of vitamins A, B and C, iron, folic acid, phosphorous and calcium. Ampalaya is a common herb used in Chinese herbology too.

The fruit's leaves are often used for children's coughs and are utilized in the treatment of skin diseases, sterility in women, as a parasiticide, an antipyretic, as well as a purgative. Like most bitter-tasting fruits and vegetables, bitter gourd stimulates digestion and can be very potent in people with dyspepsia and constipation.

Herbal Benefits of Ampalaya:

Ampalaya is noted to be an effective component in herbal medicine, and the fruit is known to help treat, or alleviate the symptoms of rheumatism and gout and ailments of the spleen and liver. It also is effective in helping lower the body's blood sugar and blood pressure levels. Below are among many of the beneficial aspects of using bitter gourd:

  • Helps to disinfect and heal cuts, wounds & burns
  • Is useful as a cough & fever remedy
  • Used in the treatment of intestinal worms and diarrhea
  • Helps prevent some types of cancers
  • Helps enhance the body's immune system to ward off infections
  • Serves as an effective antioxidant, antibacterial & antipyretic agent

How To Prepare A Herbal Ampalaya Mixture.

As the bitter fruit is famous for its many medicinal attributes, there are also other unique ways in preparing mixtures, drinks or solutions made from ampalaya. For cough, fever, worms, diarrhea, diabetes, drink a spoonful every day of grounded and juiced ampalaya leaves. For other health conditions, the fruit and leaves can both be juiced and taken orally. For wounds, burns and other skin diseases, you may apply the fruit's warmed leaves to the affected area.

Aside from the benefits mentioned above, bitter gourd is also an effective digestive agent that works by properly stimulating the secretion of gastric juices. It also aids in stimulating the liver for proper secretion of bile juices that are essential for the metabolism of body fat.

Taking juice made from bitter gourd also helps in the treatment of constipation, which is mainly caused by unhealthy eating habits and daily dietary practices. This fruit not only is good at relieving an indigestive condition, but also aids in treating constipation, by improving the movement of the gastrointestinal tract, as well as improving absorption in the intestines.

Typhus

Several different illnesses are called "typhus," all of them caused by one of the bacteria in the family Rickettsiae. Each illness occurs when the bacteria is passed to a human through contact with an infected insect.

The four main types of typhus are:

  • epidemic typhus
  • Brill-Zinsser disease>
  • endemic or murine typhus
  • scrub typhus
These diseases are all somewhat similar, although they vary in terms of severity. The specific type of Rickettsia that causes the disease also varies, as does the specific insect that can pass the bacteria along.

Epidemic typhus, which is sometimes called jail fever or louse-borne typhus, is caused by Rickettsia prowazekii, which is carried by body lice. When the lice feed on a human, they may simultaneously defecate. When the person scratches the bite, the feces (which carrys the bacteria) are scratched into the wound. Body lice are common in areas in which people live in overcrowded, dirty conditions, with few opportunities to wash themselves or their clothing. Because of this fact, this form of typhus occurs simultaneously in large numbers of individuals living within the same community; that is, in epidemics. This type of typhus occurs when cold weather, poverty, war, and other disasters result in close living conditions that encourage the maintenance of a population of lice living among humans. Some medical historians think that the Great Plague of Athens in 430 B.C. may have been epidemic typhus. Epidemic typhus is now found in the mountainous regions of Africa, South America, and Asia.

Brill-Zinsser disease is a reactivation of an earlier infection with epidemic typhus. It affects people years after they have completely recovered from epidemic typhus. When something causes a weakening of their immune system (like aging, surgery, illness), the bacteria can gain hold again, causing illness. This illness tends to be extremely mild.

Endemic typhus is carried by fleas. When a flea lands on a human, it may defecate as it feeds. When the person scratches the itchy spot where the flea was feeding, the bacteria-laden feces are scratched into the skin, thus causing infection. The causative bacteria is called Rickettsia typhi. Endemic typhus occurs most commonly in warm, coastal regions. In the United States, southern Texas and southern California have the largest number of cases.

Scrub typhus is caused by Rickettsia tsutsugamushi. This bacteria is carried by mites or chiggers. As the mites feed on humans, they deposit the bacteria. Scrub typhus occurs commonly in the southwest Pacific, southeast Asia, and Japan. It is a very common cause of illness in people living in or visiting these areas. It occurs more commonly during the wet season.

Causes and symptoms

The four types of typhus cause similar types of illnesses, though varying in severity.

Epidemic typhus causes fever, headache, weakness, and muscle aches. It also causes a rash composed of both spots and bumps. The rash starts on the back, chest, and abdomen, then spreads to the arms and legs. The worst types of complications involve swelling in the heart muscle or brain (encephalitis). Without treatment, this type of typhus can be fatal.

Brill-Zinsser disease is quite mild, resulting in about a week-long fever, and a light rash similar to that of the original illness.

Endemic typhus causes about 12 days of high fever, with chills and headache. A light rash may occur.

Scrub typhus causes a wide variety of effects. The main symptoms include fever, headache, muscle aches and pains, cough, abdominal pain, nausea and vomiting, and diarrhea. Some patients experience only these symptoms. Some patients develop a rash, which can be flat or bumpy. The individual spots eventually develop crusty black scabs. Other patients go on to develop a more serious disease, in which encephalitis, pneumonia, and swelling of the liver and spleen (hepatosplenomegaly) occur.

Diagnosis

A number of tests exist that can determine the reactions of a patient's antibodies (immune cells in the blood) to the presence of certain viral and bacterial markers. When the antibodies react in a particular way, it suggests the presence of a rickettsial infection. Many tests require a fair amount of time for processing, so practitioners will frequently begin treatment without completing tests, simply on the basis of a patient's symptoms.

Treatment

The antibiotics tetracycline or chloramphenicol are used for treatment of each of the forms of typhus.

Prognosis

The prognosis depends on what types of complications an individual patient experiences. While children usually recover well from epidemic typhus, older adults may have as much as a 60% death rate without treatment. Brill-Zinsser, on the other hand, carries no threat of death. People usually recover uneventfully from endemic typhus, although the elderly, those with other medical problems, or people mistakenly treated with sulfa drugs may have a 1% death rate from the illness. Scrub typhus responds well to appropriate treatment, but untreated patients have a death rate of about 7%.

The relatively high death rate from untreated typhus is one reason why some researchers are concerned that its causative organisms might be used in the future as agents of bioterrorism.

Prevention

Prevention for each of these forms of typhus includes avoidance of the insects that carry the causative bacteria. Other preventive measures include good hygiene and the use of insect repellents.

Key Terms

Antibody
Specialized cells of the immune system, which can recognize organisms that invade the body (such as bacteria, viruses, and fungi). The antibodies are then able to set off a complex chain of events designed to kill these foreign invaders.

Bioterrorism
The use of disease microorganisms to intimidate or terrorize a civilian population.

Endemic
Occurring naturally and consistently in a particular area.

Epidemic
A large cluster of cases all occurring at about the same time within a specific community or region.

Dengue Fever

Dengue fever is a flu-like illness spread by the bite of an infected mosquito. Dengue hemorrhagic fever is a severe, often fatal, complication of dengue fever.Dengue (DF) and dengue hemorrhagic fever (DHF) are caused by one of four closely related, but antigenically distinct, virus serotypes (DEN-1, DEN-2, DEN-3, and DEN-4), of the genus Flavivirus. Infection with one of these serotypes provides immunity to only that serotype for life, so persons living in a dengue-endemic area can have more than one dengue infection during their lifetime. DF and DHF are primarily diseases of tropical and sub tropical areas, and the four different dengue serotypes are maintained in a cycle that involves humans and the Aedes mosquito. However, Aedes aegypti, a domestic, day-biting mosquito that prefers to feed on humans, is the most common Aedes species. Infections produce a spectrum of clinical illness ranging from a nonspecific viral syndrome to severe and fatal hemorrhagic disease. Important risk factors for DHF include the strain of the infecting virus, as well as the age, and especially the prior dengue infection history of the patient.



What is the infectious agent that causes dengue?

Dengue and dengue hemorrhagic fever are caused by any of the dengue family of viruses. Infection with one virus does not protect a person against infection with another.

How is dengue spread?

Dengue is spread by the bite of an Aedes mosquito. The mosquito transmits the disease by biting an infected person and then biting someone else.

Where is dengue found?

Dengue viruses occur in most tropical areas of the world. Dengue is common in Africa, Asia, the Pacific, Australia, and the Americas. It is widespread in the Caribbean basin. Dengue is most common in cities but can be found in rural areas. It is rarely found in mountainous areas above 4,000 feet.

The mosquitoes that transmit dengue live among humans and breed in discarded tires, flower pots, old oil drums, and water storage containers close to human dwellings. Unlike the mosquitoes that cause malaria, dengue mosquitoes bite during the day.

What are the signs and symptoms of dengue fever and dengue hemorrhagic fever?

Dengue fever usually starts suddenly with a high fever, rash, severe headache, pain behind the eyes, and muscle and joint pain. The severity of the joint pain has given dengue the name "breakbone fever." Nausea, vomiting, and loss of appetite are common. A rash usually appears 3 to 4 days after the start of the fever. The illness can last up to 10 days, but complete recovery can take as long as a month. Older children and adults are usually sicker than young children.

Most dengue infections result in relatively mild illness, but some can progress to dengue hemorrhagic fever. With dengue hemorrhagic fever, the blood vessels start to leak and cause bleeding from the nose, mouth, and gums. Bruising can be a sign of bleeding inside the body. Without prompt treatment, the blood vessels can collapse, causing shock (dengue shock syndrome). Dengue hemorrhagic fever is fatal in about 5 percent of cases, mostly among children and young adults.

How soon after exposure do symptoms appear?

The time between the bite of a mosquito carrying dengue virus and the start of symptoms averages 4 to 6 days, with a range of 3 to 14 days. An infected person cannot spread the infection to other persons but can be a source of dengue virus for mosquitoes for about 6 days.

How is dengue diagnosed?

Dengue is diagnosed by a blood test.

Who is at risk for dengue?

Anyone who is bitten by an infected mosquito can get dengue fever. Risk factors for dengue hemorrhagic fever include a person's age and immune status, as well as the type of infecting virus. Persons who were previously infected with one or more types of dengue virus are thought to be at greater risk for developing dengue hemorrhagic fever if infected again.

What is the treatment for dengue and dengue hemorrhagic fever?

There is no specific treatment for dengue. Persons with dengue fever should rest and drink plenty of fluids. They should be kept away from mosquitoes for the protection of others. Dengue hemorrhagic fever is treated by replacing lost fluids. Some patients need transfusions to control bleeding.

How common is dengue?

In tropical countries around the world, dengue is one of the most common viral diseases spread to humans by mosquitoes. Tens of millions of cases of dengue fever and up to hundreds of thousands of cases of dengue hemorrhagic fever occur each year.

In the United States, approximately 100 cases of dengue are reported each year in travelers returning from tropical areas. Many more cases probably go unreported. A few persons have become infected with dengue while living in the United States. Aedes mosquitoes are found in Texas, Florida, and other southern states, and locally acquired dengue has been reported three times since 1980 in southern Texas.

Is dengue an emerging infectious disease?

Yes. All types of dengue virus are re-emerging worldwide and causing larger and more frequent epidemics, especially in cities in the tropics. The emergence of dengue as a major public health problem has been most dramatic in the western hemisphere. Dengue fever has reached epidemic levels in Central America and is threatening the United States.

Several factors are contributing to the resurgence of dengue fever:

  • No effective mosquito control efforts are underway in most countries with dengue.
  • Public health systems to detect and control epidemics are deteriorating around the world.
  • Rapid growth of cities in tropical countries has led to overcrowding, urban decay, and substandard sanitation, allowing more mosquitoes to live closer to more people.
  • The increase in non-biodegradable plastic packaging and discarded tires is creating new breeding sites for mosquitoes.
  • Increased jet air travel is helping people infected with dengue viruses to move easily from city to city.

Dengue hemorrhagic fever is also on the rise. Persons who have been infected with one or more forms of dengue virus are at greater risk for the more severe disease. With the increase in all types of virus, the occurrence of dengue hemorrhagic fever becomes more likely.

How can dengue be prevented?

There is no vaccine to prevent dengue. Prevention centers on avoiding mosquito bites when traveling to areas where dengue occurs and when in U.S. areas, especially along the Texas-Mexico border, where dengue might occur. Eliminating mosquito breeding sites in these areas is another key prevention measure.

Avoid mosquito bites when traveling in tropical areas:
  • Use mosquito repellents on skin and clothing.
  • When outdoors during times that mosquitoes are biting, wear long-sleeved shirts and long pants tucked into socks.
  • Avoid heavily populated residential areas.
  • When indoors, stay in air-conditioned or screened areas. Use bednets if sleeping areas are not screened or air-conditioned.
  • > If you have symptoms of dengue, report your travel history to your doctor.

Eliminate mosquito breeding sites in areas where dengue might occur:
  • Eliminate mosquito breeding sites around homes. Discard items that can collect rain or run-off water, especially old tires.
  • Regularly change the water in outdoor bird baths and pet and animal water containers.
