Air quality with plants that detoxify the polluted air in homes

Are plants air cleaners ?


Benzene, formaldehyde, trichloroethylene, ammonium chloride, pentachlorophenol (pcp), carbon monoxide, radiation from our appliances like computer monitors and television sets... air within our homes , classrooms, kindergartens, offices and factories is significantly more polluted than the air outside. All habitats with low ventilation and with an aim to reduce energy costs caused by air purifier devices are concerned. Awareness of this public health issue has much improved over the recent years. The U.S. Environmental Protection Agency ranks now indoor air pollution—which originates from many conventional building materials and chemicals commonly used indoor —as one of the top five threats to public health. An average American home has 100 to 200 different air contaminants.

International agencies such as WHO or Greenpeace have issued precise guidelines and warnings based on scientific findings that are worth reading and thinking over. [see our post : WHO and Greenpeace warnings ] The findings are alarming, especially considering that most of us spend our time dwelling in our homes and in office buildings.

" Since man's existence on Earth depends upon a life support system involving an intricate relationship with plants and their associated microorganisms, it should be obvious that when he attempts to isolate himself in tightly sealed buildings away from this ecological system, problems will arise. " says Wolverton a former NASA scientist in " Interior Landscape Plants for Indoor Pollution Abatement".

In the eighties the NASA researched techniques for cleansing the atmosphere in space stations to keep their habitat fit for travels over extended periods of time. Unexpected experiment results over two years in investigations supported by the NASA and the Associated Landscape contractors of America (ALCA) [see below : Scientific sources ] confirmed that certain tropical plants with low light requirements were able to use stunning mechanisms to remove harmful gases out of the air, thanks to their particular ability to photosynthesize in harder conditions. This removal is more efficient with time. We show below test results after only 24 hours of exposure. The results are just amazing. Certain plants clean air in habitats : this can be up to 90 % of the volatile pollutants.

Since then an increasing number of laboratories the world over have sustained that a wide range of volatile contaminants toxic to human health could be efficiently trapped and degraded with certain plants that have evolved in tropical forests. We show below a chart of the plants with the corresponding rates of degradation.

Further below on this page is an extended A to Z list of the plants that have been tested by various programmes following the first experiments cited above. Not only are these tropical and sub tropical plants able to tolerate low light, they are generally easy growers with low maintenance requirements. They are ideal for promoting green choices in our indoor setting. Some are supplied by aleyagarden.com

It would be demonstrated that one plant for every 10 square metres suffices to remove out of a room 70 - 90 % of the pollutants, provided that several species are mixed. The time of removal varies from a few hours to only a few days. [see below : Air Cleaning Plants in Scientific Literature]

SOURCES of the AIRBORNE POLLUTANTS :
Sources of airborne Benzene : Petroleum Products Synthetic Fibers Plastics Inks & DyesRubber Products Detergents Tobacco Smoke

Sources of airborne Formaldehyde : Foam Insulation Plywood or Particle Board
Carpeting Furniture Paper Products Cleaners

Sources of airborne Trichloroethylene : Dry Cleaning Inks & Dyes Adhesives Varnishes Lacquers Paints
 Plant species that are most efficient at air decontamination - they are listed below - originate from tropical and sub-tropical forests, where they evolved receiving light filtered through the canopy : in order to survive they used a leaf composition allowing them to photosynthesize efficiently despite the reduced light. In this connection they could find ways to process gasses in the air efficiently.

..." Cleaning up our chemical homes , changing the market to toxic - free products " :.... Chemicals out of control. Hazardous substances that are commonly used as chemical additives in consumer products can migrate out of the product over time. These same chemicals are consistently found in breast milk and umbilical cord blood, which demonstrates their wide, uncontrolled and undesired dispersion. Greenpeace testing has shown that hazardous, man-made chemicals are also widespread in house dust, rainwater and the bodies of eels. These substances can cause a wide range of health effects, including effects on the reproductive system, immune system and impacts on the nervous system and behavioural development. Exposure of the unborn child to minute quantities of hazardous substances can result in permanent irreversible damage... "

How to assess easily the quality of a dried antibiotic plant in capsule



A natural antibiotic such as Andragrophis panicualta is characteristically bitter on the tip of the tongue. With a bit of experience it is easy to assess the quality of any dried plant in capsule : with your tongue ! This is a great advantage ( but not the only one ) over fake drugs that are not easily detectable.
http://www.aleyagarden.com/hbaandropani.html

Information released by investigators linked to INTERPOL suggests that fake drugs may be used in more places than we think, such as European hospitals. The same international police focuses on pharmaceutical crime in Asian countries. In 2013 Thai patients might be treated by up to 50% of fake medcine from all sources ( drug shops, pharmacies but also hospitals ). Some suggest that in 2013 n Russia the rate would be around 20 %. read more : http://www.interpol.int/Crime-areas/Pharmaceutical-crime/Pharmaceutical-crime

I have No time for Vegetables, but I discreetly sprinkle Moringa oleifera everywhere

MORINGA OLEIFERA dried leaves

A FULL SPECTRUM SUPER NUTRIENT-RICH RAW FOOD that Your kids will not notice in their favorite dishes with :
- proteins that can be rarely found in any other herbs and green leafy vegetables.
- minerals like calcium, iron, copper, manganese, zinc, selenium, and magnesium.
-  vital B-complex  such as vitamin-B6 (pyridoxine), thiamin (vitamin B-1), riboflavin, pantothenic acid, and niacin
- and other healthy things for their immune systems.

Dry moringa oleifera and broccoli : compare their mineral contents

How many capsules of moringa oleifera can I give to my 7 years old child ?

More on this miracle food from the tropics in Wikipedia


Are the expensive Moringa capsules cost effective against other vegetables in our diets ? " Use as much as you can to minimize your total cost " , the Solver says, Moringa oleifera is even more cost effective than tomatoes ! ... and we ...are just talking about basic nutrients.
There is no doubt that if we selected more subtle phytochemicals Moringa would always be on top of the combinations with the smallest possible cost !

Clitoria ternatea and Clinacanthus nutans extracts are more efficent than drugs against the virus Herpes simplex

" I have tried all available drugs against the activity of the virus herpes simplex on my face, nothing works. I haven't seen on the internet any recommendation for a particular medicine either. What can I do ? "
A harsh and risky method consists in drying the affected area with isopropanol on a piece of cotton. However as the interest for medicinal plants increases more people affected by herpes simplex apply the extract of a plant called Clitoria ternatea, which has antiviral properties with a broad spectrum,
Clitoria ternatea
or Clinacanthus nutans.
This information is not largely spread as the economic returns are low : you can grow the plant yourself and the quantity needed for treatment is a few droplets only. Usually the extract is in glycerin. At the start of the activity, apply two to three drops of the extract -  it is important that the application be done right at the beginning of the activity and that the quantity be no more than a few drops.

In animal tests the methanolic extract of Clitoria ternatea roots demonstrated nootropic, anxiolytic, antidepressant, anticonvulsant and antistress activity. Read more on :  http://en.wikipedia.org/wiki/Clitoria_ternatea
An other study has revealed that Clitoria ternatea and 10 more tropical plants have the most potent anti-viral extracts with broad spectrum activity among a selection of thirty plants.
http://www.researchgate.net/publication/233946926_Medicinal_plants_of_Tamil_Nadu_(Southern_India)_are_a_rich_source_of_antiviral_activities
Pharmaceutical Biology, 2009; 47(5): 422–429 RESEARCH ARTICLE Medicinal plants of Tamil Nadu (Southern India) are a rich source of antiviral activities S. Vimalanathan1, S. Ignacimuthu2, and J.B. Hudson1 1Department of Pathology & Laboratory Medicine, University of British Columbia, Vancouver, Canada, and 2Entomology Research Institute, Loyola College, Chennai, India
These plants are:  Gymnema sylvestre R. Br. (Asclepiadaceae), Pergularia daemia (Forsskal) Chiov. (Asclepiadaceae), Sphaeranthus indicus L. (Asteraceae), Cassia alata L. (Caesalpiniaceae), Evolvulus alsinoides L. (Convolvulaceae), Clitoria ternatea L. (Fabaceae), Indigofera tincto- ria L. (Euphorbiaceae), Abutilon indicum G. Don. (Malvaceae), Vitex trifolia L. (Verbenaceae), Clerodendrum inerme (L.) Gaertn (Verbenaceae), and Leucas aspera Spr. (Lamiaceae), which showed anti-MCV and anti- HSV activities at a concentration as low as 0.4 μg/mL.

In Southeast Asia the flowers of Clitoria ternatea are used to colour food. In Malay cooking, an aqueous extract is used to colour glutinous rice for kuih ketan (also known as pulut tai tai in Peranakan/Nyonya cooking) and in nonya chang. In Thailand, a syrupy blue drink is made called nam dok anchan (น้ำดอกอัญชัน), it is sometimes consumed with a drop of lime juice to increase acidity and turn the juice into pink-purple. In Burmese and Thai cuisine the flowers are also dipped in batter and fried.  Read more on :  http://en.wikipedia.org/wiki/Clitoria_ternatea

Salones de Te and Llajwa : spices in Bolivia


Read in Wikipedia : " Strangely, and very much like the British, Bolivians observe an afternoon tea break. Usually the tea breaks take place around 4 and 5 pm at salones de té' (tea rooms). These tea rooms often double as bakeries so that tea and pastries are enjoyed together. Cups of black tea are usually taken with biscuits such as Galletas Maria. Often, Bolivians drink yerba maté in place of the more common black tea."  http://en.wikipedia.org/wiki/Bolivian_cuisine

Do " salones de te "  and Llajwa (Spicy Bolivian Salsa) contribute to the low cancer rates of Bolivia ?
Read on : http://www.hispanic-culture-online.com/bolivian-food.html#ixzz2Y85cEpkV
Bolivian recipes include potatoes, which Bolivians love and serve several times per day.. Bolivians use spices like ajíes and peppers in large amounts. They also use the same cooking tools as other people when making foods like lechon, and tools for grinding and spreading the condiments and spices. Bolivia makes use of a multitude of spices in their cooking as they abundant in the country... "

Wouldn't various teas be a better protection than the single Camellia sinensis

The UK has lower cancer rates than the rest of Europe. Is it related to the habit of drinking tea ? " .. when confounding factors like poor diet and smoking are avoided and animals are given nutritionally balanced food, cancer protection by tea clearly can be observed. " http://lpi.oregonstate.edu/sp-su99/tea.html But wouldn't various teas be a better protection than the single Camellia sinensis ?

My child has a sore throat and refuses to take syrups, what can I do ?


Acanthus abracteatus a plant found in the mangroves of south-east Asia and available at almost all herbal stores in the South East Asian region is one solution ( it is also available at www.aleyagarden.com  ) : dried and sold in capsules it is an efficient remedy, versatile, ready to use and cheap. At the onset of the inflammation a bit of a capsule poured in a sweet drink such as a favorite chocolate milk with honey and lemon juice is proven effective by countless uses. Some introduce also curcuma powder to the recipe to add many nutriments and a flavor.


 
 


Beyond its activity on sore throat Acanthus ebracteatus has been studied for its effects on tumor angiogenesis and on tumor growth in nude mice implanted with cervical cancer : read more on http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3437799/
