Birds of Paradise flower


crane flower

Birds of Paradise
Native to south America, birds of Paradise is also known as the crane flower. The name comes from the appearance of the bloom which looks similar to exotic, brightly colored birds in flight. Each bloom has 3 blue and orange petals while a few variations have yellow ones. This flower is a symbol of joyfulness and magnificence. The flower can also be used to indicate wonderful and exciting anticipation


He species S. nicolai is the largest in the genus, reaching 10 m tall, with stately white and blue flowers; the other species typically reach 2 to 3.5 m tall, except S. caudata which is a tree of a typically smaller size than S. nicolai. The leaves are large, 30–200 cm long and 10–80 cm broad, similar to a banana leaf in appearance but with a longer petiole, and arranged strictly in two ranks to form a fan-like crown of evergreen foliage. The flowers are produced in a horizontal inflorescence emerging from a stout spathe. They are pollinated by sunbirds, which use the spathe as a perch when visiting the flowers. The weight of the bird when standing on the spathe opens it to release the pollen onto the bird's feet, which is then deposited on the next flower it visits.

Vultures and traditional medicine




Vultures are used in southern Africa as traditional medicine 
by a number of ethnic groups for a wide range of purposes, and recent research has for the first time attempted to quantify the extent 
of such use. Considering the impacts of other factors such as habitat loss, electrocutions, collisions 
with man‐made structures and direct or indirect poisoning, the extent of harvest of vultures for traditional medicine is a threat to the continued survival of a number of species of vultures.  This ultimately threatens the survival  of traditional  customs  and  belief systems  which rely  on the continued presence and use of vultures. 

Use of vultures is an important component of traditional medicine, particularlyin southern Africa and there is evidence to suggest that traditional use is at least partly responsible for the rapid decline of vulture populations in the subcontinent. There is a widely held belief

in many African cultures that health, disease, success or misfortune are not chance events but the result of the active influence of individuals or ancestral spirits. For this reason, traditional medicine is held in high esteem in such cultures and is regularly used by a large proportion of the population. Traditional

medicines represent herbal, animal and mineral material used for physiological as well as symbolic/psychological purposes. Approximately 80% of the population in South Africa uses traditional medicine in one form or another because pharmaceutical drugs are too expensive or traditional methods are considered more appropriate.

health benefits of carrots



1. Carrots are known to be good for the overall health and specially organs like the skin, eyes, digestive system and teeth. One of carrots' fat-fighting features is their respectable fiber content, half of which is the soluble fiber calcium pectate. Soluble fiber may help lower blood-cholesterol levels by binding with and eliminating bile acids, triggering cholesterol to be drawn out of the bloodstream to make more bile acids.

2.  Cancer Prevention

Studies have shown carrots reduce the risk of lung cancer, breast cancer and colon cancer. Researchers have just discovered falcarinol and falcarindiol which they feel cause the anticancer properties.

Falcarinol is a natural pesticide produced by the carrot that protects its roots from fungal diseases. Carrots are one of the only common sources of this compound. A study showed 1/3 lower cancer risk by carrot-eating mice.

3.  Anti-Aging

The high level of beta-carotene acts as an antioxidant to cell damage done to the body through regular metabolism.  It help slows down the aging of cells.

4.  Healthy Glowing Skin (from the inside)

Vitamin A and antioxidants protects the skin from sun damage. Deficiencies of vitamin A cause dryness to the skin, hair and nails. Vitamin A prevents premature wrinkling, acne, dry skin, pigmentation, blemishes, and uneven skin tone.

5.  A Powerful Antiseptic

Carrots are known by herbalists to prevent infection. They can be used on cuts – shredded raw or boiled and mashed.

6.  Beautiful Skin (from the outside)



Carrots are used as an inexpensive and very convenient facial mask.  Just mix grated carrot with a bit of honey. See the full recipe here: carrot face mask.

WHAT IS RHINO HORN?

rhino horn


Rhino horn consists of compressed hair known as keratin, calcium and melanin. Rhinoceros, often abbreviated as rhino, is a group of five extant species of odd-toed ungulates in the family Rhinocerotidae. Two of these species are native to Africa and three to Southern Asia.

In Africa we are currently seeing the methodical and calculated reduction of rhino numbers in their natural habitat. The number of poached numbers has been escalating year-on-year over the past 5 years.

It is true that we have experienced severe poaching pressure before, and defeated it. However today, because of the insanely inflated price being paid for rhino horn, the poachers are now employing a diversity of methods which no longer fall within the traditional poaching mould. Banked-rolled by substantial finances, the modern day poacher can now afford the latest technology and buy the services of skilled people and influential officials.

Rhino poaching

The demand for rhino horn emanates from a few Asian countries (east and south East Asia ). There are many apparent reasons for the need for rhino horn, but it is used mainly as an ingredient in traditional medicines and not as an aphrodisiac as is often widely reported. In more recent times it is being marketed to cure non-traditional conditions such as cancer.

Rhino horn is valuable because of the simple economics of the situation – demand far exceeds supply.

South Africa has the largest rhino population in the world of both white and black rhino. We have traditionally been seen as a difficult environment within which poachers could operate. As the easier targets (i.e. other countries) have lost all their rhino, so the demand has shifted to South Africa . We also know that crime of all types is rampant in this country and rhino poaching is an extension of this.

BENEFITS OF GARLIC


Garlic is a species in the onion genus. Garlic is easy to grow and can be grown year-round in mild climates. While sexual propagation of garlic is indeed possible, nearly all of the garlic in cultivation is propagated asexually, by planting individual cloves in the ground.[6] In cold climates, cloves are planted in the autumn, about six weeks before the soil freezes, and harvested in late spring. The cloves must be planted at sufficient depth to prevent freeze/thaw which causes mold or white rot

To treat skin infections

The chemical ajoene found in garlic may help treat fungal skin infections like ringworm and athlete’s foot.




Blood thinning

The anti-clotting properties of ajoene found in garlic help in preventing the formation of blood clots in the body. Hence, it may also increase the risk of bleeding after surgery.

Reduce blood pressure

Angiotensin II is a protein that helps our blood vessels contract thereby increasing the blood pressure. Allicin in garlic blocks the activity of angiotensin II and helps in reducing blood pressure. The polysulphides present in garlic are converted into a gas called hydrogen sulphide by the red blood cells. Hydrogen sulphide dilates our blood vessels and helps control blood pressure.



Protect heart

Garlic protects our heart against cardiovascular problems like heart attacks and atherosclerosis. This cardio-protective property can be attributed to various factors. With age, the arteries tend to lose their ability to stretch. Garlic may help reduce this and may also protect the heart from the damaging effects of free oxygen radicals. The sulphur-containing compounds of garlic also prevent our blood vessels from becoming blocked and slow the development of atherosclerosis (hardening of the arteries). The anti-clotting properties of ajoene help prevent clots from forming inside the blood vessels.


Reduce cholesterol

Garlic has the ability to moderately lower our blood triglycerides and total cholesterol and reduce arterial plaque formation.




Side-Effects

There are a few people who are allergic to garlic. Symptoms of garlic allergy include skin rash, temperature and headaches. Also, garlic could potentially disrupt anti-coagulants, so it's best avoided before surgery. As with any medicine, always check with your doctor first and tell your doctor if you are using it.
