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.

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

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

Habitat : Agavaceae, originally native to Mexico, and the United States in Arizona and Texas. Today it cultivated worldwide as an ornamental plant. It has become naturalized in many regions including the West Indies, parts of South America, the southern Mediterranean Basin, parts of Africa, India, China, Thailand, New Zealand, Australia. It grows on  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.

Although it is called the century plant, it typically lives only 10 to 30 years. It has a spread of about 6–10 ft (1.8–3.0 m) with gray-green leaves of 3–5 ft (0.9–1.5 m) long, each with a prickly margin and a heavy spike at the tip that can pierce to the bone. Near the end of its life, the plant sends up a tall, branched stalk, laden with yellow blossoms, that may reach a total height of up to 25–30 ft (8–9 m) tall….....CLICK & SEE

Its common name derives from its semelparous nature of flowering only once at the end of its long life. 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…....CLICK  &   SEE
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.

leaves used medicinally by Indians of the Southwestern US.  Also a modern source of steroids.  A demulcent, laxative and antiseptic, agave sap is a soothing and restorative remedy for many digestive ailments. It is used to treat ulcers and inflammatory conditions affecting the stomach and intestines, protecting these parts from infection and irritation and encouraging healing. Agave has also been employed to treat a wide range of other conditions, including syphilis, tuberculosis, jaundice, and liver disease.  Agave sap has very soothing properties and can be used interchangeably with aloe vera on topical wounds and burns.  The sisal agave is a source of hecogenin, the substance that is the starting point in the production of corticosteroids.  Water in which agave fiber has been soaked for a day can be used as a scalp disinfectant and tonic in cases of falling hair.

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. 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’


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

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.
