(NaturalNews) People have long known about the psychological benefits of brightening their homes and offices with decorative houseplants. What many may be overlooking are the physical health benefits of having plenty of these plants to remove harmful pollutants from the air and replace them with fresh oxygen.

Not long ago, indoor air pollution was not considered a health threat; most homes and public buildings leaked so much that air often was replaced every couple of hours. After energy shortages occurred in the 1970s, more and more people began to insulate their houses and office buildings to conserve energy and lower heating and cooling costs. As a result, indoor air might linger for five hours or more allowing pollutants to accumulate. Moreover, synthetic building materials used in modern construction have been found to produce potential pollutants that remain trapped in unventilated buildings. These trapped pollutants can result in what is often called the Sick Building Syndrome.

In the late 1980s, a study by NASA and the Associated Landscape Contractors of America (ALCA) resulted in excellent news for homeowners and office workers everywhere. The study concluded that common decorative houseplants such as bamboo palms and spider plants not only make indoor spaces more attractive, they also help to purify the air. While it's a well known fact that plants convert carbon dioxide into oxygen through photosynthesis, the NASA/ALCA study showed that many houseplants also remove harmful elements such as trichloroethylene, benzene, and formaldehyde from the air. With our ultra modern homes and offices that are virtually sealed off from the outside environment, this study is just as important now as when it was first published.

The NASA study, Foliage Plants for Removing Indoor Air Pollutants from Energy Efficient Homes, was conducted by Dr. B.C. Wolverton, Anne Johnson, and Keith Bounds in 1989. While it was originally intended to find ways to purify the air for extended stays in orbiting space stations, the study proved to have implications on Earth as well.

Under controlled conditions, NASA and ALCA spent two years testing 19 different common house plants for their ability to remove these common pollutants from the air. Of the 19 plants they studied, 17 are considered true houseplants, and two, Gerbera Daisies and Chrysanthemums, are more commonly used indoors as seasonal decorations.

The advantage that houseplants have over other plants is that they are adapted to tropical areas where they grow beneath dense tropical canopies and must survive in areas of low light. These plants are thus ultra-efficient at capturing light, which also means that they must be very efficient in processing the gasses necessary for photosynthesis. Because of this fact, they have greater potential to absorb other gases, including potentially harmful ones.

NASA found that some of the plants were better than others for absorbing pollutants, with certain houseplants found to remove as much as 87 percent of indoor air pollutants within 24 hours. However, all of the plants had properties that were useful in improving overall indoor air quality. NASA also noted that some plants are better than others in treating certain chemicals. For example, English Ivy worked better than some other plants for treating air contaminated with Benzene. The Peace Lily was very effective in treating Trichloroethylene and the Bamboo Palm worked well for filtering Formaldehyde.

After conducting the study, NASA and ALCA came up with the following list of plants most recommended for treating air pollution. Note that all the plants in the list are easily available from your local nursery.

Heartleaf Philodendron – Philodendron scandens `oxycardium'
Elephant Ear Philodendron – Philodendron domesticum
Cornstalk Dracaena – Dracaena fragrans `Massangeana'
English Ivy – Hedera helix,
Spider Plant – Chlorophytum comosum
Janet Craig Dracaena – Dracaena deremensis `Janet Craig'
Warneck Dracaena – Dracaena deremensis `Warneckii'
Weeping Fig – Ficus Benjamina
Golden Pothos – Epipiremnum aureum
Peace Lily – Spathiphyllum `Mauna Loa'
Selloum Philodendron – Philodendron selloum
Chinese Evergreen – Aglaonema modestum
Bamboo or Reed Palm – Chamaedorea sefritzii
Snake Plant – Sansevieria trifasciata
Red-edged Dracaena – Dracaena marginata

Here is a list of the pollutants NASA tested for and the plants they found that worked the best for each one:

Trichloroethylene (TCE)

Trichloroethylene is primarily used in the metal degreasing and dry cleaning industries; also in printing inks, paints, lacquers, varnishes, adhesives. In 1975 the National Cancer Institute reported that an unusually high incidence of hepatocellular carcinomas was observed in mice given TCE by gastric intubation and now considers this chemical a potent liver carcinogen.

The NASA study found that the best plants for removing trichloroethylene are the Gerbera Daisy, Chrysanthemum, Peace lily, Warneckei, Dracaena marginata

Benzene

Benzene is a very commonly used solvent and is also present in many common items including inks, oils, paints, dyes, plastics, rubber, dyes, detergents, gasoline, pharmaceutical, tobacco smoke, synthetic fibers. In addition it is used in the manufacture of explosives.

Benzene has long been known to irritate the skin and eyes. In addition, it has been shown to be mutagenic to bacterial cell culture and has shown embryotoxic activity and carcinogenicity in some tests. Evidence also exists that benzene may be a contributing factor in chromosomal aberrations and leukemia in humans. Repeated skin contact with benzene will cause drying, inflammation, blistering and dermatitis.

Acute inhalation of high levels of benzene has been reported to cause dizziness, weakness, euphoria, headache, nausea, blurred vision, respiratory diseases, tremors, irregular heartbeat, liver and kidney damage, paralysis and unconsciousness. In animal tests inhalation of benzene led to cataract formation and diseases of the blood and lymphatic systems. Chronic exposure to even relatively low levels causes headaches, loss of appetite, drowsiness, nervousness, psychological disturbances and diseases of the blood system, including anemia and bone marrow diseases.

The best plants for removing benzene were determined to be English Ivy, Dracaena marginata, Janet Craig, Warneckei, Chrysanthemum, Gerbera Daisy, Peace lily

Formaldehyde

Formaldehyde is a ubiquitous chemical found in virtually all indoor environments. The major sources which have been reported and publicized include urea-formaldehyde foam insulation (UFFI) and particle board or pressed wood products used in manufacturing of the office furniture bought today. It is used in consumer paper products which have been treated with UF resins, including grocery bags, waxed papers, facial tissues and paper towels. Many common household cleaning agents contain formaldehyde. UF resins are used as stiffeners, wrinkle resisters, water repellents, fire retardants and adhesive binders in floor coverings, carpet backings and permanent-press clothes. Other sources of formaldehyde include heating and cooking fuels like natural gas, kerosene, and cigarette smoke.

Formaldehyde irritates the mucous membranes of the eyes, nose and throat. It is also a highly reactive chemical which combines with protein and can cause allergic contact dermatitis. The most widely reported symptoms from exposure to high levels of this chemical include irritation of the eyes and headaches. Until recently, the most serious of the diseases attributed to formaldehyde exposure was asthma. However, the Environmental Protection Agency (EPA) has recently conducted research which has caused formaldehyde to be strongly suspected of causing a rare type of throat cancer in long-term occupants of mobile homes, where particle board and other sources of formaldehyde are used extensively.

When it comes to removing formaldehyde, the best plant choices are Azalea, Philodendron, Spider plant, Golden Pothos, Bamboo palm, Corn plant, Chrysanthemum, Mother-in-law's tongue.

Many people feel that the use of houseplants is not needed if they are using an air purifier. However, research has shown that even if you use a HEPA air filter or an ionic air purifier, there is a lot of difference that can still be made by many common house plants, which act as a living air purifier. With the exception of an activated carbon filter, common indoor air filters, such as HEPA or ionizers, will totally miss the toxic household gases, such as carbon monoxide, formaldehyde, and volatile organic gases (VOG).

According to NASA, one plant should be used for every 100 to 120 square feet of office or living space and the plants should be in at least six inch containers with nothing covering the potting soil. In addition to removing pollutants in your home or office, plants also make for a more pleasant place to live and work – where people feel better, perform better, and enjoy life more. Here are some of the other benefits from having indoor plants:

Plants are a Source of Oxygen – Plants take in carbon dioxide and produce oxygen through the process known as photosynthesis. The more plants you have, the more oxygen you will receive.

Plants Make You Happy – House plants make people feel calmer and more optimistic, says Bruno Cortis, M.D., a Chicago cardiologist. Interestingly, he says that studies have shown that hospital patients who face a window with a garden view recovered more quickly than those who had to look at a wall.

Plants Fight Fatigue and Colds – According to a University of Agriculture in Norway study, indoor plants can reduce fatigue, coughs, sore throats and other cold-related illnesses by more than 30 percent, partially by increasing humidity levels and decreasing dust.

Plants at the Office – Major corporations and work environments are beginning to catch on that adding plants indoors does wonders for employee health and morale. According to one study published in Rehabilitation Literature, a manufacturing company integrated plants into its office so that no employee would be more than 45 feet from greenery. The result? Company administrators said they noticed enhanced creativity and increased productivity in employees. One popular plant to use in offices is the Dragon Tree plant. Besides being one of the most effective in removing harmful impurities from the air, it's exotic looks adds character to any room.

It is important to note though that not all plants are good as indoor air cleaners and that some plants are poisonous and should be handled with care, or not at all if you have small children. Some examples of toxic plants include: Nightshade, Creeping Charlie, Foxglove, Oleander, Sago Plant, Privet, Rhododendron, Umbrella Plant, Ivy, Ripple ivy, Sweet Pea, Vinca, Spider Mum, and Poinsettia. Consumers looking for houseplants that purify air should probably steer away from the above named plants if they have young children and indoor pets, as these plants can sometimes be fatal if consumed.

(NaturalNews) You know cold season is hitting its peak when crumpled tissues start piling up next to bottles of cough syrup and antibiotics. It seems the moment someone gets the sniffles they feel compelled to visit their doctor, and more often than not, they leave their appointment with multiple prescriptions in hand. You have to wonder: is all this medication necessary?

The answer is no. Home treatment for colds can be even more effective than medications, and without the harmful side effects. Old-fashioned cold remedies can often be made with what you already have in your pantry, and the cost is much less prohibitive than the expense of a doctor`s visit and several prescriptions. Next time you feel a cold coming on, try some of these simple remedies to alleviate your symptoms and shorten the duration of your cold.

Avoid Over-the-Counter Drugs

Although these medications claim to be helpful, they can turn your cold into a nightmare. A runny nose may be irritating, but drying up nasal passages with decongestants is a surefire way to encourage the build-up of bacteria. Instead, keep you sinuses clear with natural saline sprays.

You can also make your own saline solution at home with a half teaspoon of salt dissolved in a cup of warm water. Use a bulb syringe to place three or four drops of the liquid into each nostril. Gently breathe in and avoid blowing your nose for at least thirty seconds. This gives the mixture time to break down some of the build-up in your sinuses. Repeat this several times each day until nasal passages are clear.

Over-the-counter cough syrups should also be avoided. Instead, mix lemon juice with warm water and add a bit of honey. This home remedy can soothe your cough and works equally well for sore throats.

Sinus pressure and pain is often treated with over-the-counter pain medication like acetaminophen and ibuprofen. These are only moderately effective and are known for their potential toxic side effects. Try placing a heating pad or warm washcloth over the area instead. Repeat as needed.

To speed your recovery, try natural supplements like Vitamin C, zinc and Echinacea. Taken at the first sign of a cold, these can often prevent a bad cold from developing. These supplements can also shorten the duration of your cold.

Stay Hydrated

Lack of fluids prevents healing and sets the stage for infection. Staying hydrated can prevent an advanced sinus infection which is more difficult to treat at home. Drink 8-10 glasses of water each day while you`re sick. Avoid ice water which can irritate your throat.

You can also get more fluids into your system by drinking herbal teas and sipping warm broth. Chamomile tea is known for soothing coughs and sore throats. Chicken broth, especially real broth made at home, is known for its strong healing effects. The warmth of the liquids alone can often alleviate many of your cold symptoms.

Since dry conditions exacerbate cold symptoms and drain your body of fluids, setting up a humidifier can speed the healing process. Just be sure to change the water regularly and keep the system clean.

Detoxify

A cold weakens your immune system and causes the build up of toxins. It is highly beneficial to help the body flush out these toxins by practicing a few simple methods of detox. You should start each day with several minutes of dry skin brushing. With a natural hair brush, make sweeping strokes toward the heart over all parts of the body.

After dry brushing, take a hot shower. Hot water will encourage perspiration, which rids the body of toxins. At the end of your shower, turn the water to cool for up to 60 seconds. Switch back to hot water for another 60 seconds. Alternate hot and cold water like this for at least three cycles. This entire process should be done at least once every day until your cold is gone.

When you`ve got a cold, it`s more important than ever to get your rest and make healthy food choices. A rested and well-nourished body is the best medicine for fighting off a cold.
