Botanical Name : Hepatica americana
Family: Ranunculaceae
Genus: Hepatica
Species: H. nobilis
Kingdom: Plantae
Order: Ranunculales

Common Names: Liverwort, Ker-gawl ,Hepatica tribola, Hepatica nobilis,American Liverleaf, Alumroot, Round Lobed Hepatica

Habitat : Hepatica americana is native to the eastern United States and to central and eastern Canada. It grows on the dry woods. Mixed woods, often in association with both conifers and deciduous trees, usually in drier sites and more acid soils, from sea level to 1200 metres. ( Rich or rocky wooded slopes, ravines, mossy banks, ledges. Usually on acid soils.)
Description:
Hepatica americana is a herbaceous perennial, growing to 0.3 m (1ft) by 0.2 m (0ft 8in) at a slow rate.
It is hardy to zone (UK) 4. It is in flower from Apr to May. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Bees, flies, beetles, lepidoptera……..CLICK &  SEE  THE  PICTURES

USDA hardiness zone : 3-9

Suitable for: light (sandy) and medium (loamy) soils. Suitable pH: acid, neutral and basic (alkaline) soils and can grow in very alkaline soils.
It can grow in full shade (deep woodland) semi-shade (light woodland) or no shade. It prefers moist soil.
Cultivation:
Landscape Uses:Rock garden, Woodland garden. Prefers a deep light soil with leafmold. Grows well on limey woodland soils in half shade, though it also succeeds in deep shade and in full sun[1]. Plants resent root disturbance and should be placed in their permanent positions as soon as possible. This species is closely related to H. acutiloba. A greedy plant, inhibiting the growth of nearby plants, especially legumes. Special Features: Attractive foliage, North American native, Naturalizing, Attracts butterflies.
Propagation:
Seed – sow in a moist soil in a shady position. The stored seed requires stratification for about 3 weeks at 0 – 5°c. Germination takes 1 – 12 months at 10°c. It is probably worthwhile sowing the seed as soon as it is ripe in a shady position in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division just as the leafless plant comes into flower in late winter. Replant immediately into their permanent positions.
Medicinal Uses:
Hepatica americana was used widely by natives and colonists to treat a variety of ailments. A tea made from the leaves is laxative. It is used in the treatment of fevers, liver ailments and poor indigestion. At one time it became a cult medicine as a liver tonic and 200,000 kilos of dried Hepatica leaves were used in 1883 alone. Externally, the tea is applied as a wash to swollen breasts[

It was used most commonly as a leaf tea to treat liver disorders. This was thought to work because the plants leaves are shaped much like the human liver. This practice of treating organ ailments with the plants that most resembled them is known as the “doctrine of signatures.” The practice originated in China and, fortunately, is no longer

While rarely found in herbal remedies today, it is a mild astringent and a diuretic. It stimulates gall bladder production and is a mild laxative. Its astringency has also stopped bleeding in the digestive tract and the resultant spitting of blood. Historically, liverwort has been used for kidney problems and bronchitis. It’s active constituent, protoaneminin, has been shown to have antibiotic action. The Russians use it in their folk medicine and also to treat cattle with mouth sickness.

Known Hazards : Although no specific mention has been seen for this species, most plants in this family are poisonous. This toxicity is usually of a low order and the toxic principle is destroyed by heat or by drying.

Older People ‘Miss Skin Cancer Signs’

Older people are less likely to get skin changes checked by a doctor, leading to a steep rise in cancer deaths, say researchers.

CLICK & SEE

The East of England Cancer Registry reports that deaths from melanoma among the over 65s have tripled in the past 30 years.

The elderly are more likely to be diagnosed when the cancer has spread.

Cancer Research UK says pensioners should keep a close eye on moles and report suspicious changes to GPs.

Melanoma is the most dangerous form of skin cancer, and is linked to cumulative sun exposure over a lifetime.

This means that the over-65s are more likely to develop the disease in the first place.

Overlooked
However, unlike younger people, the registry data reveals that the classic signs of a cancerous mole are being overlooked among a host of other changes to older skin.

This means that by the time the mole cannot be ignored, the cancer is likely to be at a more advanced stage, making it far harder to treat.

Dr Jem Rashbass, the director of the East of England Cancer Registry, which collates data on cancer to identify trends among the population, said: “Although there have been some improvements in the number of over 65s being diagnosed with melanoma at a late stage, the figures suggest that more needs to be done to raise awareness about skin cancer among this generally retired population.”

The registry data revealed that, for every year since 1997, significantly more elderly people have been diagnosed with late-stage melanoma compared with under-65s.

While the death rate among older people rose from four deaths per 100,000 people in 1979 to 11.4 per 100,000 in 2008, the death rate for people aged between 15 and 64 has remained stable.

Sara Hiom, from Cancer Research UK, said: “Melanoma is a largely preventable disease. Summer may be over, but the damage to skin cells shown by sunburn can remain long after the redness fades.”

Her colleague Caroline Cerny, from the charity’s “Sunsmart” campaign, highlighted the classic warning signs of melanoma.

She said: “If a mole is as big as a pencil-top eraser, bleeds, is sore or itchy, uneven in colour or has jagged edges, then people should visit their GP without delay.”

Green Tea ‘May Block Lung Cancer’

[amazon_link asins=’B0042IMPTU,B00DE4NPV0,B00PFDH0IC,B003D4F2US,B06XJM1SCW,B000WB1YSE,B000GG0BNE,B01G0S3Y44,B0016BFR4G’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’74921435-6fba-11e7-af6f-03caaad76f89′]

Drinking green tea may offer some protection against lung cancer, say experts who studied the disease at a medical university in Taiwan.
………………..……click & see
The latest work in more than 500 people adds to growing evidence suggesting the beverage has anti-cancer powers.

In the study, smokers and non-smokers who drank at least a cup a day cut their lung cancer risk significantly, a US cancer research conference heard.

The protection was greatest for people carrying certain genes.

But cancer experts said the findings did not change the fact that smoking is bad for health.

Daily cuppa:-

Green tea is made from the dried leaves of the Asian plant Camellia sinesis and is drunk widely across Asia.

The rates of many cancers are much lower in Asia than other parts of the world, which has led some to link the two.

Laboratory studies have shown that extracts from green tea, called polyphenols, can stop cancer cells from growing.

But results from human studies have been mixed. Some have shown a protective effect while others have failed to find any evidence of protection.

In July 2009, the Oxford-based research group Cochrane published a review of 51 studies on green tea and cancer which included over 1.5 million people.

They concluded that while green tea is safe to drink in moderation, the research so far is conflicting about whether or not it can prevent certain cancers.

Reduced risk:-

Dr I-Hsin Lin, of Shan Medical University, found that among smokers and non-smokers, people who did not drink green tea were more than five times as likely to get lung cancer than those who drank at least one cup of green tea a day.

Among smokers, those who did not drink green tea at all were more than 12 times as likely to develop lung cancer than those who drank at least a cup a day.

Researchers then analysed the DNA of people in the study and found certain genes appeared to play a role in the risk reduction.

Green tea drinkers, whether smokers or non smokers, with certain types of a gene called IGF1, were far less likely to develop lung cancer than other green tea drinkers with different types of this gene.

Yinka Ebo, of Cancer Research UK, said the findings should not be used as an excuse to keep smoking.

“Smoking tobacco fills your lungs with around 80 cancer-causing chemicals. Drinking green tea is not going to compensate for that.

“Unfortunately, it’s not possible to make up for the harm caused by smoking by doing other things right like eating a healthy, balanced diet.

“The best thing a smoker can do to reduce their risk of lung cancer, and more than a dozen other cancer types, is to quit.”

Cancer Boost from Whole Carrots

[amazon_link asins=’B000P6H3V8,B004X1YUFI,B000P6G0EO,B01CLHRAFC,B017AAOGDO,B005MHRK5Y,B00837XYD2,B007C7H412,B00AMO2BI8′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’775d4c9e-46d9-11e7-9cf4-a92710868456′]

The anti-cancer properties of carrots are more potent if the vegetable is not cut up before cooking, research shows.

Chef’s tip: Chop after cooking

Scientists found “boiled before cut” carrots contained 25% more of the anti-cancer compound falcarinol than those chopped up first.

Experiments on rats fed falcarinol have shown they develop fewer tumours.

The Newcastle University study will be presented at NutrEvent, a conference on nutrition and health, to be held in France.

All you need is a bigger saucepan
Dr Kirsten Brandt:
Lead researcher Dr Kirsten Brandt, from Newcastle University’s School of Agriculture, Food and Rural Development, said: “Chopping up your carrots increases the surface area so more of the nutrients leach out into the water while they are cooked.

“By keeping them whole and chopping them up afterwards you are locking in nutrients and the taste, so the carrot is better for you all round.”

The Newcastle scientist, along with colleagues at the University of Denmark, discovered the health benefits of falcarinol in carrots four years ago.

Heat effect
Rats fed on a diet containing carrots or falcarinol were found to be one-third less likely to develop full-scale tumours than those in the control group.

Since then the scientists in Newcastle have been studying what happens when carrots are chopped and cooked.

The latest findings show that when carrots are heated, the heat kills the cells, so they lose the ability to hold on to the water inside them, increasing the concentration of falcarinol as the carrots lose water.

However, the heat also softens the cell walls, allowing water-soluble compounds such as sugar and vitamin C to be lost via the surface of the tissue, leading to the leaching out of other compounds such as falcarinol.

If the carrot is cut before being boiled, the surface area becomes much greater – and so the loss of nutrients is increased.

More tasty
Dr Brandt added that in blind taste studies the whole carrots also tasted much better.

Eight of ten people favoured the whole vegetables over those that were pre-chopped.

This is because the naturally occurring sugars which are responsible for giving the carrot its distinctively sweet flavour were also found in higher concentrations in the carrot that had been cooked whole.

Dr Brandt said: “The great thing about this is it’s a simple way for people to increase their uptake of a compound we know is good for you.

“All you need is a bigger saucepan.”

Dr Kat Arney, of the charity Cancer Research UK, remained unconvinced that keeping carrots whole would have any impact on cancer risk.

She said: “When it comes to eating, we know that a healthy balanced diet – rich in a range of fruit and vegetables – plays an important part in reducing the risk of many types of cancer, rather than any one specific food.”
