Separate male and female flowers are borne on the one plant – male flowers are distinguished by a number of stamens extending from the base of the flower.Flowering during September to November. The flowers are followed by oval-shaped, red berries about 15-20 mm long which darken to deep purple when ripe in summer. In contrast with T.lanceolata and T.stipitata, the seeds of T.insipida are not used commercially for culinary purposes but retain the peppery flavour and are edible.

Edible Uses:
The culinary quality of Tasmannia stipitata was recognized in the mid-1980s by horticulturist Peter Hardwick, who gave it the name ‘Dorrigo pepper’, and Jean-Paul Bruneteau, then chef at Rowntrees Restaurant, Sydney. It is mainly wild harvested from the Northern Tablelands of New South Wales. Dorrigo pepper has a woody peppery note in the leaves and fruit/seed. The hot peppery flavor is derived from polygodial, an essential oil component, common to most species in the family.

Tasmannia stipitata, Dorrigo pepper, is also used as a spice and was the original pepperbush used in specialty native food restaurants in the 1980s. Dorrigo pepper is safrole free and has a strong peppery flavour.

High BP ‘Raises Silent Stroke Risk’

[amazon_link asins=’B00U2WMWDO,B06XPPH2R6,B01N4LMXMZ,B01H31OF8G,B0744H5W2H,B01N4LHOBX,B01HXUJ9S8,B00KPQB2NS,B01M716HEZ’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’0c7f7d00-1144-11e8-8d2a-795204504c2c’]

Individuals over 60, especially those with high blood pressure, are at an increased risk of experiencing a “silent stroke“, a new study
has found.

“Silent” strokes are strokes that don’t result in any noticeable symptoms but cause brain damage.

The research has been published in the July 28, 2009, print issue of Neurology, the medical journal of the American Academy of Neurology.

“These strokes are not truly silent, because they have been linked to memory and thinking problems and are a possible cause of a type of dementia,” said study author Perminder Sachdev, MD, PhD, of the University of New South Wales in Sydney, Australia.

“High blood pressure is very treatable, so this may be a strong target for preventing vascular disease,” the expert added.

The study involved 477 people age 60 to 64 who were followed for four years. At the beginning of the study 7.8% of the participants had the silent lacunar infarctions, small areas of damage to the brain seen on MRI that never caused obvious symptoms. They occur when blood flow is blocked in one of the arteries leading to areas deep within the brain, such as the putamen or the thalamus.

At the end of the study, an additional 1.6% of the participants had developed “silent” strokes.

People with high blood pressure were 60% more likely to have silent strokes than those with normal blood pressure.

Also, people with another type of small brain damage called white matter hyperintensities were nearly five times as likely to have silent strokes as those without the condition.

African Plant Helps Stop Bleeding

[amazon_link asins=’B00LCBFH6I,B00HJTH5L2,B00R3DG53I,B00TPYY0EO,B071LP3HGK,B01FDZUKFG,B01LJYB5AY,0486493458,B00QSI0QMA’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’8973b5bf-eec1-11e7-84ce-554e03e2a38a’]

The leaves of Aspilia africana, a plant used in African traditional medicine, can stop bleeding, block infection and speed wound healing, a new study from Nigeria confirms.

The leaves and flowers of A Africana, a bristle-covered herb known as the “hemorrhage plant,” have been used to stanch bleeding, remove foreign bodies from the eyes, treat scorpion stings, and for several other purposes across the African continent, note Dr Charles O Okoli and colleagues at the University of Nigeria.

Dr Okoli is currently located in Sydney, Australia at the University of New South Wales.

To test the plant’s medicinal properties, Okoli and his team performed a series of lab and animal experiments comparing the effects of an extract of the powdered leaves in methanol, and two different portions or fractions containing hexane or methanol. They report their findings in BMC Complementary and Alternative Medicine.

The extract and the fractions of the plant significantly reduced bleeding and clotting time in rats, the researchers found, with the methanol fraction having the strongest effect.
