Boabab - “The Tree of Life"

By On May 13, 2018


The name Adansonia digitata was given by Linnaeus, the generic name honouring Michel Adanson who had been first decribed Baobab in the eighteenth century at Senegal. Darwin documented baobab trees on the St Jago in the Cape Verde Islands in 1832 and he commented on their size and longevity. Adansonia digitata L. is the most widely spread of the Adansonia species on the African continent which belongs to the family of Bombacaceae a sub family of the Malvaceae. Adansonia species comprises of 8 different species with large, spectacular, nocturnal flowers. One of these species is the A. digitata L, it occurs throughout the drier parts of Africa. A second species is restricted to North-Western Australia (A. gibbosa) and the remaining six species are endemic to Madagascar. The African baobab is known by a very large number of local names: Monkey bread tree, Ethiopian sour gourd, Cream of tartar tree, Senegal calabash fruit, Upside-down tree, boab, boaboa, bottle tree, upside-down tree.

India’s folklore holds several theories regarding baobab’s arrival to our country. Hindu myths allege that the trees came into creation when the demons and gods churned the sea. This swelling and swirling created nine jewels, one of which was the baobab tree. Today, locals still refer to the majestic specimens as kalpvriksha or the wish-fulfilling tree. Today 33 countries in Africa have some of the oldest strains of the tree, but no botanist can say about its real land of origin. Indeed, the subject of baobab’s origin is controversial, speculating and disputing topic for centuries. Recent DNA dating technology provide some insight to scientists on the issue: A 2009 study published in “Molecular Ecology” reveals that the most likely origin is somewhere in West Africa. Baobab trees possess incredible features due to its evolutionary history their roots, for instance have undergone centuries of refinement to possess the ability to store water. They can thrive in the harshest desert conditions.
Today, baobabs grow mostly throughout tropical Africa, southern Arabia, Madagascar, India, Sri Lanka, Australia, Barbados and Hawaii. Baobabs are widely distributed in belts across Africa. The baobab tree is an icon of the African savannah, a symbol of life and positivity in a landscape where little else can thrive and can have a lifespan of up to 5000 years. The baobab is a prehistoric species which predates both mankind and the splitting of the continents over 200 million years ago. Native to the African savannah where the climate is extremely dry and arid the Baobab has adapted to its environment and its nutrient-dense fruit in the dry season is a fortunate for existence of life. This is how it became known as "The Tree of Life".
Availability of Baobab in India
Baobabs are a rare sight in India. Savanur, a small town located in the Haveri District of Karnataka, boasts of its three majestic baobab trees reputed to be the oldest in the country. Each of them is allegedly over 5,000 years old (without tree rings, none can say for sure), and the girth of one tree measures an impressive 18 meters. A few baobabs grow in Madhya Pradesh’s ruined city, Mandavgad. Outside the Vasai fort in Maharashtra, one can behold an ancient tree growing amidst the fort’s stoic, 15th century facades. One or two baobabs grow in Gujarat’s cities of Kutch, Bhanagar and Baroda. In Chennai, a single baobab tree grows in the Theosophist Society Gardens, a site dedicated to biological preservation. Despite the baobab’s usefulness, the tree faces extinction in India and other parts of the world. Bihar’s Sanjay Gandhi Biological Park maintains one tree as part of its conservation efforts to preserve the baobab. Baobab known in India in different names, Goraksi,Gorak-amli (Hindi), Aane hunase (Kannada), Baubab (Marathi), Chitrala (Sanskrit), Aanipuliya maram (Tamil), Brahma malika (Telegu).

Baobab trees can reach up to 30 metres high and up to a huge 50 metres in circumference. The baobab tree is undoubtedly one of nature's most iconic images. Its majestic presence is familiar to anyone who has spent time in rural Africa - but it is also well known all across the world thanks to its starring roles in Disney’s Lion King (it is Rafiki the monkey’s tree), Avatar (The Tree of Souls), Madagascar and the famous children's novel The Little Prince..
Importance of Baobab:
The Baobab tree has large whitish flowers which open at night. The fruit which grows up to a foot long, contains tartaric acid and vitamin C and can either be sucked or soaked in water to make a refreshing drink. They can also be roasted and ground up to make a coffee-like drink. The fruit is not the only part of the Baobab that can be used. The bark is pounded to make rope, mats, baskets, paper and cloth the leaves can be boiled and eaten. Fresh baobab leaves provide an edible vegetable similar to spinach which is also used medicinally to treat kidney and bladder disease, asthma, insect bites, and several other maladies. The tasty and nutritious fruits and seeds of several species are sought after, while pollen from the African and Australian baobabs is mixed with water to make glue.
Women in Africa have turned to the baobab fruit as a natural source of health and beauty for centuries. Baobab is the only fruit in the world to dry naturally on the branch. This means the fruit simply needs to be harvested, deseeded and sieved to produce a 100% natural fruit pulp powder. Baobab powder is deliciously sweet and citrussy - ideal for boosting smoothies, drinks, breakfast and any dish. Natives believe that women living in kraals (Zambia) where baobabs are plentiful have more children than those living outside baobab zones. They eat soup made from baobab leaves, which is rich in vitamins. This compensates for any deficiency in their diet. Doctors have confirmed that this indeed brings about a higher fertility rate.
Medicinal Applications of Baobab
Traditional medicine: The bark, roots, leaves, fruits and seeds of baobab are widely used by indigenous peoples for human and animal medicines. Leaves and fruit pulp are used in folk medicine as an antipyretic to overcome fevers. The powdered leaves can be used as anti-stress properties. They are variously used to treat fatigue, as a tonic and for insect bites, guinea worm and internal pains and to treat dysentery. The fruit pulp and powdered seeds are used in cases of dysentery and to promote perspiration.
The bark, leaf, fruit pulp and seed are used in India to reduce swellings. Baobab fruit pulp improves the iron status of children with low iron levels in their blood. An aqueous bark extract of A. digitata is traditionally used in Nigeria for treating sickle-cell anaemia.
Baobab stem-bark is considered beneficial in Nigeria as a heart tonic with diuretic properties. In Senegal baobab leaves and the fruit pulp are used for external bleeding, (baobab leaf) is taken for anaemia and also claimed to lower blood pressure. In Benin the Otomari prepare a decoction from the seeds known as mantofamen, it is used to treat high blood pressure. The leaves and pulp are also used in the treatment of haemorrhoids. Juice made from fruit pulp and seeds of A. digitata are given to treat haemoptysis.
In West Africa the sap or a paste from roasted crushed seeds, is applied to the diseased teeth and gums, the bark decoction is used as a mouthwash for toothache. The bark has been used for treating caries and the fruit stalk used as a tooth stick in Mali and India. Children with sore gums (gingivitis) are treated with roasted, powdered seeds.
In West Africa, eye complaints, such as conjunctivitis are treated by bathing the eyes in a decoction of baobab bark from young trees, an infusion of the leaves and flowers. Baobab seed is taken to relieve stomach ache in adults. The roots of A. digitata are used for treating stomach ache as well. The fruit pulp in water or milk is taken alone with gruel of millet or a decoction of the crushed or roasted seeds and water, is used to treat intestinal inflammations, diarrhoea and dysentery throughout much part of Africa.
The fresh or dried roots are boiled in two to four glasses of water, two cups are taken in the morning as a remedy for urine retention and urinary tract infections. In West African, a solution of the baobab fruit matrix and water or preferably rice water in which fruit matrix has been boiled, was used to treat smallpox. Patients with measles had a thick paste of baobab pulp, cereal flour and water placed on their eyes several times a day.
In South Africa the Venda use a baobab bark decoction together with the root of Osyrislanceolatato treat sexually transmissible diseases. The bark, leaf, fruit rind, pulp and seed are also used in India for treating venereal diseases.
A poultice of leaves crushed in hot water is used in Nigeria for healing circumcision wounds. Wounds may also be treated with an application of a seed paste. The gum and a powder scraped from the outside of the baobab fruit are used for cleansing wounds and sores and promoting granulation. In many parts of the African countries, there is a common but unconfirmed belief that baobab bark, pulp and seeds are an antidote to Strophanthus spp (an arrow poison).
Thus, in Tanzania, a specially delegated member of any Shangaan hunters squeeze the sap from baobab bark into the wound of an animal killed by a poisoned arrow to neutralise the poison. According to the active principle of the arrow poison is strophanthin, consisting of a mixture of glycosides, including K-strophanthin, B. cymarin, etc. ‘Adansonin’, present in the stem-bark is considered to have a cardiotonic effects, while the tannins in the baobab bark precipitate the glycosides.
Pregnant women in Malawi drank baobab juice made from fruit pulp mixed with water. Australian Aboriginal mothers with newborn babies also used to drink boabab fruit pulp crushed into water. Baobab roots and flowers have unspecified gynaecological applications but in Benin the flowers are used to speed the ejection of the foetus. The bark and leaves for treating afterbirth retention.
 In Zimbabwe pregnant women use the bark from mature baobabs to enlarge their birth canals in order to reduce pain during delivery. In India, to relieve delivery pains, pregnant women bath in water in which baobab bark has been boiled. A mixture of powdered roots of A. digitata and Sterculia setigera plus bulrush millet bran (Penisetum glaucum) to stimulate lactation, while in Mali, the fruit pulp is eaten to stimulate lactation.
A mixture of the powdered roots of A. digitata, Acacia albida, Bauhinia rufescens, Waltheria indica is recommended for pellagra and kwashiorkor. While in southern Africa kwashiorkor is also treated by providing an infusion of baobab root. Baobab bark is used as a remedy against rickets in children as a tonic. A root decoction is given as a tonic for lassitude and as a strengthening medicine. The pulp is eaten as an appetizer in Benin. Gelfand stated that David Livingstone successfully treated indolent sores with poultices of powdered baobab leaf and considered that Livingstone’s ulcers may have been of dietetic origin. In Benin, a decoction known as tutonakankount is prepared from baobab leaves crushed in boiling water to which a few grams of potash are added; it is used to cure iron and calcium deficiencies. The bark, leaf, fruit pulp and seed are used in India for relieving body and joint pains.

Spinach - The energy donor

By On May 06, 2018

          
Spinach (Spinacia oleracea) is an edible flowering plant in the family Amaranthaceae.The word “spinach” is derived from the Persian word “ispanai” which means “green hand”, which later became spanachia in Latin, and ultimately spinach in English.
Spinach is thought to have originated in ancient Persia (Iran). Spinach made its way to China in the 7th century when the king of Nepal sent it as a gift to this country. It was only brought to that continent in the 11th century, when the Moors introduced it into Spain. In fact, spinach was known as "the Spanish vegetable" in England. Today, the United States and the Netherlands are among the largest commercial producers of spinach.
Popeye popularized spinach. Fresh spinach retains the delicacy of texture and green color. Raw spinach has a mild, slightly sweet taste that can be refreshing in salad. Spinach is used raw in salads and cooked as a pot-herb. Spinach can be used as a source of vitamin A, B1, B2, niacin and calcium. The crop also has a hypoglycemic effect that can be used in treating urinary calculi and lung inflammation. The seeds can be used as a laxative and for treating breathing difficulties and liver inflammation.
Spinach is considered to be one of the healthiest foods on earth, with researchers identifying more than a dozen different types of flavonoid antioxidants alone that are present in spinach, not to mention all of its other nutrients. Spinach nutrition has powerful anti-inflammatory and antioxidant abilities, and if you combine that with its very low amount of calories, it is easily one of the most nutrient-dense foods in diet.

Spinach contains special protective carotenoid compounds that have been linked with decreasing the risk of many diseases, including cancer, heart disease, diabetes, neurodegenerative diseases, and obesity. Spinach’s phytonutrients include such carotenoids as beta-carotene, lutein, and zeaxanthin. Spinach also supplies flavonoids, which are a type of powerful antioxidant that protect against disease by fighting free radical damage within the body. These protective compounds make spinach one of the best anti-ageing foods.


Spinach varieties are classified by leaf types, and there are mainly three types:

·         Savoy has dark green, crinkly and curly leaves and a dark green colour; savoy spinach leaves are springy and crisp.
·         Semi-savoy is a hybrid variety with slightly crinkled leaves. It has the same texture as savoy, but it is not as difficult to clean. It is grown for both fresh market and processing.

Baby spoon spinach: Rich-green, baby spoon spinach is Savoy type spinach, but as its name suggests is smaller in size than regular savoy. Crispy and coarse, it is sweeter than the larger variety. The tender small stems are edible too. Baby spinach is great for use in salads owing to its taste and delicate texture; smooth types are used for baby spinach.

Safety

Spinach contains a high amount of oxalate. Individuals with a history of oxalate containing kidney stones should avoid over consumption. A low oxalate diet is usually defined as containing less than 50 milligrams of oxalate per day. Spinach has more than 50 milligrams so is best avoided. Spinach also contains high levels of oxalic acid, which in excess can inhibit the absorption of other important nutrients such as calcium. Lightly cooking spinach is thought to reduce the oxalic acid content
Health benefits of spinach

1. Beneficial for Weight Loss: Spinach leaves help in weight reduction as it is low in calories and fat. It is very nutritious and has a good quality of fat soluble dietary fibre. This fibre aids in digestion, prevents constipation, maintains low blood sugar and curbs overeating. Thus, this leafy vegetable is often recommended to diet.

2. Anti-cancer: Spinach is rich in flavonoids with anti-cancer properties, found to be effective in slowing down cell division in human stomach and skin cancer cells. Moreover, spinach has proven to be effective in providing protection against the occurrence of aggressive prostate cancer. Spinach contains chlorophyll as active component which found to be effective at blocking the carcinogenic effects of heterocyclic amines which are generated when grilling foods at a high temperature.

3. Eye Health: Spinach contains antioxidants lutein and zeaxanthin in plentiful which protect the eye from cataract and age related macular degeneration (ARMD). Zeaxanthin is an important dietary carotenoid which is absorbed into the retinal macula lutea in the eyes, providing light filtering functions. Spinach also contains vitamin A which is required for maintaining healthy mucus membranes and essential for normal eyesight. Vitamin C and vitamin A found in spinach nutrition can help to fight UV light damage which can lead to skin cancer or the appearance of aged skin.

4. Healthy Bones: Spinach is rich in vitamin K which is vital for maintains bone health by controlling the over activation of osteoclasts. These are the cells that aid in breaking down the bone structure over a short period of time. Vitamin K also promotes the synthesis of osteocalcin, the protein that is essential for maintaining the strength and density of bones. Spinach is a good alternative to dairy products as it gives proper substitute to calcium, thus preventing the occurrence of osteoporosis. It is an important protein diet for vegetarians as it helps in building the muscle tissues as well as supporting the collagen growth. Adequate vitamin K consumption is important for good health, as it acts as a modifier of bone matrix proteins, improves calcium absorption and may reduce urinary excretion of calcium.

5. Lowers Hypertension: Hypertension or high blood pressure is responsible for causing kidney disease, heart ailments and stroke. Consuming spinach is beneficial in lowering hypertension as some of its constituents help to reduce stress and anxiety. The nutrients play a critical role in keeping the balance of Na- K pump by lowering the potassium in body. Vitamin C also plays an important role in lowering hypertension.

7. Diabetes management: Spinach contains an antioxidant known as alpha-lipoic acid, which has been shown to lower glucose levels, increase insulin sensitivity and prevent oxidative stress-induced changes in patients with diabetes. Studies on alpha-lipoic acid have also shown decreases in peripheral neuropathy and autonomic neuropathy in diabetics.
8. Asthma prevention: The risks for developing asthma are lower in people who consume a high amount of certain nutrients. One of these nutrients is beta-carotene, of which spinach is an excellent source.
9. Lowering blood pressure: because of its high potassium content, spinach is recommended to those with high blood pressure to nullify the effects of sodium in the body. A low potassium intake may also be a risk factor in developing high blood pressure as a high sodium intake.
10. Healthy skin and hair: Spinach is high in vitamin A, which is necessary for sebum production to keep hair moisturized. Vitamin A is also necessary for the growth of all bodily tissues, including skin and hair. Spinach and other leafy greens high in vitamin C are imperative for the building and maintenance of collagen, which provides structure to skin and hair. Iron-deficiency is a common cause of hair loss, which can be prevented by an adequate intake of iron-rich foods, like spinach.
11. Promotes regularity: Spinach is high in fiber and water content, both of which help to prevent constipation and promote a healthy digestive tract. Lower levels of inflammation protect the vulnerable lining of the digestive tract and stomach, reducing the chances of developing leaky gut syndrome or other digestive disorders. Spinach is also a good source of dietary fiber. Fiber is needed to maintain digestive health because it helps with regular bowel movements, carries waste and toxins out of the body, prevents constipation or diarrhea, and can detoxify the digestive tract.

In animal studies, the group given spinach supplements, the animals showed reversal in age related signs of cognitive impairment and overcame some of the difficulty with and motor skills. The group given spinach experienced improvements in the ability to complete behavioral tasks and improvements on scores for cognitive tests. This suggests antioxidants found in spinach can delay both mental and physical signs of aging.
