Lifts for a Core Balance

March 14th, 2010

Develop your lower body as well as core strength with these challenging rear-leg balancing poses. You’ll immediately feel the work in your legs, buttocks, back and abdominals. Begin with your hands resting on the seat of the chair for added stability. Once you find your balance and feel comfortable with this pose, try the more advanced move by extending your arms out in front of you, resting them on the top of the chair.

1. Stand facing a sturdy chair or a bench. Inhale, bend forward at the hips and place your hands on the seat of the chair or bench, making sure that your wrists are directly below your shoulders. Shift your weight over your right leg and slowly raise your left leg up to hip height. Be sure to keep both knees straight and both hips and shoulders squarely facing the floor. (The knee and toes of your raised leg should be pointed toward the floor.) Pause while holding your leg at this level for three complete breaths. Lower the leg and repeat on the other side.

2. Stand facing a sturdy chair or a short wall. Inhale, bend foward at the hips and lightly rest your hands on the top of the chair back or on the short wall. Shift your weight to your right leg and slowly raise your left leg up to hip height. Be sure to keep both knees straight and both hips and shoulders squarely facing the floor. (The knees and toes of your raised leg should be pointed toward the floor.) Pause while holding your leg at this level for three complete breaths. Lower the leg and repeat on the other side.

Hourglass Figure not Always Healthy

March 14th, 2010

Having an imperfect body may not be all that bad, says a new article, which claims that ‘imperfections’ come with substantial benefits for some women.
………..
The report has been published in the December issue of Current Anthropology. The hormones that make women physically stronger, more competitive and better able to deal with stress also tend to redistribute fat from the hips to the waist, according to Elizabeth Cashdan, an anthropologist at the University of Utah.

So in societies and situations where women are under pressure to procure resources, they may be less likely to have the classic hourglass figure.

Cashdan’s hypothesis aims to explain a peculiar observation. Women around the world tend to have larger waist-to-hip ratios—more cylindrical rather than hourglass-shaped bodies—than is considered optimal.

Medical studies have shown that a curvy waist-to-hip ratio of 0.7 or lower is associated with higher fertility and lower rates of chronic disease. Studies have also shown that men prefer a ratio of 0.7 or lower when looking for a mate.

The preference makes perfect sense, according to evolutionary psychologists, because the low ratio is a reliable signal of a healthy, fertile woman.

But in data that Cashdan compiled from 33 non-Western populations and 4 European populations, the average waist-to-hip ratio for women is above 0.8. If 0.7 is the magic number both in terms of health and male mate choice, why are most women significantly higher? That’s where the hormones come in.

Androgens, a class of hormones that includes testosterone, increase waist-to-hip ratios in women by increasing visceral fat, which is carried around the waist. But on the upside, increased androgen levels are also associated with increased strength, stamina, and competitiveness. Cortisol, a hormone that helps the body deal with stressful situations, also increases fat carried around the waist.

“The hormonal profile associated with high WHR (waist-to-hip ratio) may favour success in resource competition, particularly under stressful circumstances,” writes Cashdan.

“The androgenic effects—stamina, initiative, risk-proneness, assertiveness, dominance—should be particularly useful where a woman must depend on her own resources to support herself and her family,” the expert added.

In other words, trading the benefits of a thin waist for better ability to collect resources may be a good deal in certain societies and situations. And there is evidence that male mate preferences may reflect this trade-off, according to Cashdan.

The plant prefers light (sandy) and medium (loamy) soils and requires well-drained soil. The plant prefers acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It requires dry or moist soil and can tolerate drought.

Cultivation:
Requires a very well-drained soil and a sunny position. Plants are only hardy on the south coast of England, where they succeed from Torbay westwards. A monocarpic species, the plant lives for a number of years without flowering but dies once it does flower. However, it normally produces plenty of suckers during its life and these take about 10 – 15 years in a warm climate, considerably longer in colder ones, before flowering. This plant is widely used by the native people in its wild habitat, it has a wide range of uses. Members of this genus are rarely if ever troubled by browsing deer.

Propagation:
Seed – surface sow in a light position, April in a warm greenhouse. The seed usually germinates in 1 – 3 months at 20°c. Prick out the seedlings into individual pots of well-drained soil when they are large enough to handle and grow them on in a sunny position in the greenhouse until they are at least 20cm tall. Plant out in late spring or early summer, after the last expected frosts, and give some protection from the cold for at least their first few winters. Offsets can be potted up at any time they are available. Keep in a warm greenhouse until they are well established


Edible Parts:
Leaves; Root; Sap; Seed; Stem.

Edible Uses: Drink.You
The heart of the plant is very rich in saccharine matter and can be eaten when baked. Sweet and delicious, but rather fibrous. It is partly below ground. Can be dried for future use or soaked in water to produce a flavourful beverage. Seed – ground into a flour. Flower stalk – roasted. Root – cooked. Sap from the cut flowering stems is used as a syrup. The sap can also be tapped by boring a hole into the middle of the plant at the base of the flowering stem. It can be fermented into ‘Mescal’, a very potent alcoholic drink.

Medicinal Actions & Uses:-
Antiseptic; Diuretic; Laxative.

The sap is antiseptic, diuretic and laxative.

Disclaimer:The information presented herein is intended for educational purposes only. Individual results may vary, and before using any supplements, it is always advisable to consult with your own health care provider.

Other Uses
Brush; Fibre; Miscellany; Needles; Paper; Pins; Soap; Thatching.

The leaves contain saponins and an extract of them can be used as a soap. It is best obtained by chopping up the leaves and then simmering them in water – do not boil for too long or this will start to break down the saponins. A very strong fibre obtained from the leaves is used for making rope, coarse fabrics etc. To make hair brushes and brushes for cleaning, the dried matter of a dead and rotten leaf was knocked free from the fibres, which were then bent in two. the upper end of this brush was wrapped with a cord and the bent portion was covered with a cloth. The loose fibres were cut to the right length and hardened by burning the ends. A paper can also be made from the fibre in the leaves. The thorns on the leaves are used as pins and needles. The dried flowering stems are used as a waterproof thatch and as a razor strop.

Women’s Natural Scent More Seductive Than Perfume

March 14th, 2010

Women might want to think twice before spritzing Chanel No. 5. A new study suggests that a woman’s natural scent may be all she needs.

…………
Recent research shows that a man’s testosterone levels, which are linked with sexual interest, are significantly higher when they smell the shirt of a woman who is ovulating.

Other studies have linked higher levels of testosterone with an increase in sexual arousal as well.

In surveys, men have reported being more attracted to ovulating women. The new study builds on this research by measuring the response of men to a specific chemical cue

Agave Americana

March 13th, 2010

Botanical Name: Agave americana
Family  : Agavaceae
Genus : Agave
Common Name :Century Plant

Habitat : South-western N. America. Naturalized in the Mediterranean.     Original habitat is unknown but it grows wild in Mexico on cultivated land and in pine woods. Sandy places in desert scrub at elevations around 200 metres in Texas and eastern Mexico.


Description:
-
An evergreen Perennial growing to 7.5m by 2.5m at a slow rate.It has a spreading rosette (about 4 m/13 ft wide) of gray-green leaves up to 2 m (6.6 ft) long, each with a spiny margin and a heavy spike at the tip that can pierce to the bone. Its common name derives from its habit of only occasionally flowering, but when it does, the spike with a cyme of big yellow flowers may reach up to 8 m (26 ft) in height. The plant dies after flowering, but produces suckers or adventitious shoots from the base, which continue its growth.

....

The average lifespan is around 10 years.

Cultivated varieties include the “marginata” with yellow stripes along the margins of each leaf, “medio-picta” with a central white band, “striata” with multiple yellow to white stripes along the leaves, and “variegata” with white edges on the leaves

It is hardy to zone 9 and is not frost tender. It is in leaf all year. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Lepidoptera (Moths & Butterflies), bats.

The plant prefers light (sandy) and medium (loamy) soils and requires well-drained soil. The plant prefers acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It requires dry or moist soil and can tolerate drought.


Cultivation
:-
Requires a very well-drained soil and a sunny position. The agave is not very hardy in Britain tolerating temperatures down to about -3°c if conditions are not wet. It succeeds outdoors on the south coast of England from Torbay westwards. Plants survived lower temperatures during the very cold winters from 1985/1987 and were unharmed at Glendurgan gardens in West Cornwall. A monocarpic species, the plant lives for a number of years without flowering but dies once it does flower. However, it normally produces plenty of suckers during its life and these continue growing, taking about 10 – 15 years in a warm climate, considerably longer in colder ones, before flowering. This plant is widely used by the native people in its wild habitat, it has a wide range of uses. In a warm climate suckers take 10 – 15 years to come into flower. Members of this genus are rarely if ever troubled by browsing deer.

Propagation:-

Seed – surface sow in a light position, April in a warm greenhouse. The seed usually germinates in 1 – 3 months at 20°c. Prick out the seedlings into individual pots of well-drained soil when they are large enough to handle and grow them on in a sunny position in the greenhouse until they are at least 20cm tall. Plant out in late spring or early summer, after the last expected frosts, and give some protection from the cold for at least their first few winters. Offsets can be potted up at any time they are available. Keep in a warm greenhouse until they are well established

Different Uses:
If the flower stem is cut without flowering, a sweet liquid called agua miel (“honey water”) gathers in the heart of the plant. This may be fermented to produce the drink called pulque. The leaves also yield fibers, known as pita, which are suitable for making rope, matting, coarse cloth and are used for embroidery of leather in a technique known as piteado. Both pulque and maguey fibre were important to the economy of pre-Columbian Mexico. Production continues today to a much lesser extent. Agave nectar (also called agave syrup) has recently been marketed as a healthful natural sugar substitute.
The sap is quite acidic and can be quite painful if it comes in contact with the skin. It can form small blisters.

Tequila is made from a different species, the Blue Agave (A. tequilana).

Edible Uses:-
Edible Parts: Leaves; Sap; Seed; Stem.

The heart of the plant is very rich in saccharine matter and can be eaten when baked. Sweet and nutritious, but rather fibrous. It is partly below ground. Seed – ground into a flour and used as a thickener in soups or used with cereal flours when making bread. Flower stalk – roasted. Used like asparagus. Sap from the cut flowering stems is used as a syrup  or fermented into pulque or mescal. The sap can also be tapped by boring a hole into the middle of the plant at the base of the flowering stem.

Medicinal Actions & Uses:-
Antiseptic; Diaphoretic; Diuretic; Laxative; Miscellany; Odontalgic; VD.

The sap of agaves has long been used in Central America as a binding agent for various powders used as poultices on wounds. The sap can also be taken internally in the treatment of diarrhoea, dysentery etc. The sap is antiseptic, diaphoretic, diuretic and laxative. An infusion of the chopped leaf is purgative and the juice of the leaves is applied to bruises. The plant is used internally in the treatment of indigestion, flatulence, constipation, jaundice and dysentery. The sap has disinfectant properties and can be taken internally to check the growth of putrefactive bacteria in the stomach and intestines. Water in which agave fibre has been soaked for a day can be used as a scalp disinfectant and tonic in cases of falling hair.

Steroid drug precursors are obtained from the leaves. A gum from the root and leaf is used in the treatment of toothache. The root is diaphoretic and diuretic.  It is used in the treatment of syphilis. All parts of the plant can be harvested for use as required, they can also be dried for later use. The dried leaves and roots store well.

Disclaimer:The information presented herein is intended for educational purposes only. Individual results may vary, and before using any supplements, it is always advisable to consult with your own health care provider.

Other Uses:-
Fibre; Insecticide; Miscellany; Needles; Paper; Pins; Soap; Soil reclamation; Thatching.

The plant contains saponins. An extract of the leaves is used as a soap. The roots are used according to another report. It is likely that the root is the best source of the saponins that are used to make a soap.

Chop up the leaves or the roots into small pieces and then simmer them in water to extract the saponins.

Do not over boil or you will start to break down the saponins[K]. There is a report that the plant has insecticidal properties, but further details are not given. A very strong fibre obtained from the leaves is used for making rope, coarse fabrics etc. A paper can also be made from the leaves. The thorns on the leaves are used as pins and needles. The dried flowering stems are used as a waterproof thatch and as a razor strop. The plants are used in land-reclamation schemes in arid areas of the world.

The leaves also yield fibers, known as pita, which are suitable for making rope, matting, coarse cloth and are used for embroidery of leather in a technique known as piteado. Both pulque and maguey fibre were important to the economy of pre-Columbian Mexico. Production continues today to a much lesser extent.

Agave nectar (also called agave syrup) has recently been marketed as a healthful natural sugar substitute


Known Hazards
:    Contact with the fresh sap can cause dermatitis in sensitive people. The plants have a
very sharp and tough spine at the tip of each leaf. They need to be carefully sited in the garden.

Fluctuating BP ‘Warning Sign for Stroke’

March 13th, 2010


People with occasionally high blood pressure are more at risk of stroke than those with consistently high readings, research suggests.

……..
Current guidelines focus on measuring average blood pressure levels to spot and prevent the chance of a stroke.

But research suggests doctors should no longer ignore variation in test results and give drugs that produce the most steady blood pressure levels.

The Stroke Association called for national guidelines to be overhauled.

In the first of the series of studies published in The Lancet, UK and Swedish researchers looked at the variability in blood pressure readings at doctors’ checks.

They found those with fluctuating readings at different GP visits had the greatest risk of future stroke regardless of what their average blood pressure reading was.

A review of previous trials also found that the differences in effectiveness of several blood pressure drugs could be explained by how well they kept blood pressure on an even keel.

Some drugs, in particular beta blockers, were shown in a separate study in The Lancet Neurology, to increase variation in a patient’s blood pressure.

‘Major implications’

Professor Peter Rothwell of the Department of Clinical Neurology at the University of Oxford, who led the research, said the findings have major implications for how GPs spot and treat people at high risk of stroke.

“At the moment, the guidelines for GPs say not to believe a one-off unusual reading, to bring the patient back and measure again, and as long as it’s not consistently high, there is no need to treat.

“What we’re saying is don’t discount that one-off high blood pressure reading.”

He added that GPs would also need to make sure they prescribe the most effective drug combinations – ideally one that lowers blood pressure but also stabilises it.

It is not know exactly why occasional spikes would increase a person’s risk of stroke but it is thought it puts undue stress on the system.

If you get rapid fluctuations that can cause turbulent flow of blood which can cause damage and stiffening in the arteries,” said Professor Rothwell.

He said anyone with high blood pressure who tests themselves at home might want to mention to their GP if they spot variations in their results.

The National Institute for Health and Clinical Excellence’s guidelines on high blood pressure is in the process of being rewritten and these latest studies will be taken into account.

Joe Korner, director of communications at The Stroke Association said people who have occasional high blood pressure readings – known as episodic hypertension – are often not treated.

“With this new research it is now important that the clinical guidelines about treating high blood pressure are reviewed.

“In the meantime we urge GPs to read this research to help them prescribe the best treatment for people at risk of stroke.”

Experts stressed that those already prescribed medication for high blood pressure should not worry or stop taking their pills.

Professor Peter Weissberg, medical director at the British Heart Foundation said: “Current practice is not wrong, but this might add a new measure to help doctors make decisions on who to treat for hypertension and which drug to use.”

Dumbbells Aid in Tricep-Toning

March 13th, 2010

Adding core stability to this arm exercise will shape and tone the muscles in your midsection as well as the backs of your upper arms, called the triceps.

1. Hold a 5- to 10-pound dumbbell in each hand and lie on a full-length round roller. Place your hips and head on the roller (you can use a yoga block under your head if necessary). Put your feet flat on the floor, hip-width apart, toes and knees facing forward. Straighten your arms above your chest and press the ends of the dumbbells together.

2. Inhale, slowly lower the dumbbells until they’re just above your forehead, pausing with your wrists at shoulder height. Then exhale, contracting the backs of your upper arms to reverse directions and move the dumbbells up to the start position. Do not “lock out” at the elbows. Hold for two seconds at the top of the lift and repeat until you have done 12 reps. Rest for 20 seconds and repeat for a total of three sets.

Eat Slow and Cut Your Calories

March 12th, 2010

For ages, mothers have admonished children to slow down and chew their food. It turns out they’re onto something.

………………….

Researchers have found evidence that when people wolf their food, they end up consuming more calories than they would at a slower pace. One reason is the effect of quicker ingestion on hormones.

In one recent study, scientists found that when a group of subjects were given an identical serving of ice cream on different occasions, they released more hormones that made them feel full when they ate it in 30 minutes instead of 5.

In other words, it can’t hurt to slow down and savor your meals.

Coke’s New ‘Healthy Front’ May Be Just a Big Bluff

March 12th, 2010

Diet Coke and the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health have joined forces to raise awareness about women’s risk of heart disease. Diet Coke’s Red Dress Program will take center stage at high-profile events.

……..

The Center for Science in the Public Interest points out that Coca-Cola, whose products are not exactly heart healthy, is a strange partner for the NHLBI.

Are such partnerships a benign win-win? History suggests otherwise.

In 1984, Kellogg cooked up a partnership with the National Cancer Institute to put health claims for fiber on the boxes of All-Bran cereals. In doing so, Kellogg (and NCI) went around the FDA and undermined that agency’s control over health claims on food packages — leading to problems that the agency is still struggling to fix.

Description:

This is an aromatic perennial herb growing an erect stem with widely spaced leaves, each lance-shaped to nearly triangular and toothed. The leaves are up to 8 centimeters long and 7 wide. The inflorescence is a dense spike of many flowers. Each flower has long sepals tipped with bright purple and tubular corollas in shades of pink and purple. The fruit is a light brown, fuzzy nutlet about 2 millimeters long. The plant was used medicinally by several Native American groups, especially the leaves.

.....

This dicot (dicotyledon)  has its most active growth period in the spring and summer . The Nettleleaf Giant Hyssop has dark green foliage and inconspicuous red flowers, with a smattering of conspicuous green fruits or seeds. The greatest bloom is usually observed in the late spring, with fruit and seed production starting in the summer and continuing until summer. Leaves are not retained year to year. The Nettleleaf Giant Hyssop has a long life span relative to most other plant species and a rapid growth rate. At maturity, the typical Nettleleaf Giant Hyssop will reach up to 5 feet high, with a maximum height at 20 years of 0 inches.

It is hardy to zone 8. It is in flower in August, and the seeds ripen in September. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Bees. The plant is self-fertile. It is noted for attracting wildlife.
The plant prefers light (sandy) and medium (loamy) soils and requires well-drained soil. The plant prefers acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It requires dry or moist soil.

Cultivation:
Prefers a warm sunny sheltered position and a well-drained soil. Succeeds in most soils. This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c. A plant is growing in a sunny bed at Kew Botanical gardens and appears fully hardy there[K]. This species withstands temperatures down to about -40°c when fully dormant. The flowers are very attractive to bees.
