We are the World Blogfest # 31: Searching for new remedies against the malarial parasite …



# WATWB – Soup War on Malaria?!  At long last we are researching indigenous remedies – but in this case finding them via the cuisine of London’s ethnic community …

#WATWB


… looking into the apparent blocking of the malarial parasite in the process of transmission, through various broths.



Malarial parasite connecting to a red blood cell
In one primary school – the pupils were asked to bring in samples of clear soup made from traditional family recipes (European, North African and Middle Eastern).   (London being one of the most ethnically diverse cities in the world).




The broths varied: vegetarian, chicken, or beef based were all home-made – thus no obvious particular ingredient leading to an antimalarial activity … but which was known about.


Chicken Soup
Imperial College of Science, Technology and Medicine have been working with the students testing their families’ broths … against two stages of the parasite: when it can infect mosquitoes, and when it can cause the disease in humans.



The research is ongoing … but the other benefit has been to engage the children in the idea of research: where it can start, and how results are evidenced … how many of them will now become scientists?


Winsor McCay's 1912 animated film:
"How a Mosquito Operates"
We live in interesting times … and as usual to this curious mind two other appropriate links appeared … a BBC programme on Li Shizhen (1518 – 1593): who is considered to be the greatest scientific naturalist of China …



… and an Ethiopian Swedish chef and restaurateur,  Marcus Samuelsson, now living in New York … again from a conversation on the Beeb … bringing together those culinary influences.




“In Darkness, Be Light.”

Li Shizhen - and his Compendium of Materia Medica 





Be thankful ... we, the privileged human race, can learn so much from history and each ecosystem.

Oak Galls and Theophilus Presbyter ...



Falling leaves, trees shedding their fruits and nuts, change of seasons … brought me to remember the method of early ink … the crushed gall of an oak mixed with rainwater to start with …

Oak trees turning to autumnal gold


Thank goodness the human has always wanted to write about items of interest … even in the very early civilisations … Greek, Egyptian, Roman, the Dark Ages into the Middle Ages …



Jean Mielot (d 1472) writing in
a Scriptorium

Theophilus Presbyter (c 1070 – 1125 AD), is probably the pseudonym of Roger of Helmarshausen, a German Monk … who it is thought compiled detailed descriptions of various medieval craft arts …


… one of his works is divided into three books:


  • ·       Painting techniques, paints, and inks, especially for the illumination of texts and paintings of walls;
  • ·       Production of stained glass and techniques of glass painting;
  • ·       Techniques of gold-smithing and metalwork.


Theophilus and the other Benedictine monks would have worked in a Scriptorium (“a place for writing”), a necessary adjunct to a library.


Oak Apple Gall
It appears to have been Theophilus who recorded the ‘recipe’ for Iron Gall ink, which became the prescribed ink for all governmental records – in England the Exchequer finances, royal income, sheriffs’ accounts, chancery rolls – administrative accounts … all recorded and held as pipe rolls.


Example of a Pipe Roll by
the Ticknor Organisation

Pipe rolls are named after the “pipe” shaped formed by rolled up parchments on which records were normally written.






Oak Apples or Oak Galls are the common name for the large, round, vaguely apple-like gall commonly found on many species of oak.


From De Materia Medica



It may surprise you that the oak apple gall ink was the main medium used in writing in the Western World from the 5th century to the 19th century, and was still being used in the last century:


  • ·       Da Vinci doodled with it …
  • ·       Bach used it for his compositions …
  • ·       the Constitution of the United States was drafted in it …
  • ·       and the Domesday Survey (1086 AD), William the Conqueror’s historical record of his lands, property etc in England after he conquered in 1066 AD.


There are two types of ink … carbon ink, made of charcoal or lamp-black mixed with a gum … this was used in the ancient and eastern worlds … with recipes for the ink occurring until the 12th century.




Jean Mielot - held in Brussels Royal
Library (by unknown miniaturist)
The second is this metal-gall ink, usually iron gall, made by mixing a solution of tannic acids with ferrous sulphate (copperas); it too requires added gum as a thickener, rather than an adhesive.  After the 12th century … this was the ink used by the craftsmen in later medieval manuscripts.




Gall inks were to be found in the third century, but there was no literary tradition of explaining them until the early 12th century, confirmed by Theophilus.  


Quill with some ancient letters
The scribe needed to work quickly … it was a two-handed operation … the left hand held a knife for sharpening the quill and for erasing mistakes … before the ink had really soaked in to the vellum.


Here it is shown that gall-ink
is destroying paper


Gall-ink could not be used with paper as it is too acidic eating through the paper, but in the days of calfskin vellum, the tannic acid ink bit into the page making the lettering indelible.





A facsimile of De Materia Medica with vellum cover
It is thought that Theophilus put a ‘recipe’ down for iron-gall ink into his book on crafts … and thus the scribes in the Middle Ages started to use that ink … giving us the many basic dark black/brown ink inscribed words we find in our ancient manuscripts today – throughout the early western world.


Male Gall Wasp
Galls are caused by wasps laying their eggs in developing leaf buds … there are a variety of galls … our oak apple gall, the oak marble gall, oak artichoke gall and the acorn cup gall to name a few of these distinctive forms.


So we have wasps to thank that we have records which can be read today … but also the ingenuity of our forebears … crushing galls with rainwater, and realising that a stronger ink was possible when different earths were used.

Home made oak gall inks


Iron gall ink is tannic acid … which occurs naturally in plants, fruits and other life.  It has been extracted and utilised by civilisations for thousands of years.





Look out for the oak galls as you walk the woods this autumn … and think where these blogs originated from millennia ago … a funny old world!


Three quills in different stages
of preparation
Should you be able to find some fresh felled oak ... it often displays blue-black stains caused by a reaction between the iron from the axe, and the tannin of the wood to produce a substance identical to old-fashioned writing ink; check too for brass screws to secure newly seasoned timber, because the acid in the oak will badly corrode steel screws.  (I couldn't!)

Babel of Struggling through the A-Z ...




The Babel of the A-Z is over … so well done all for successfully completing another year – I really missed it … but am ready: one big project over for 2017!

Ruins of Babylon as seen from Saddam Hussein's
Summer Palace ... don't let our world get like this?!

I will be happy to read your Reflections … always interesting to see everyone’s views … but to take you away from your sheer exhaustion … I shall be whisking you off to South Africa in a few days for some much needed R & R …

Different to our lives 60 or 70 years ago ... but then that’s change …





Path through early summer greens - at Old Sarum
We just need to help all peoples to understand the need for our countryside, our villages, our farming communities … to see how life has grown and developed – the history of our lives, as well as how beneficial all these areas are …





A small holding for sale in Wales ... some
repair needed to these barns
Let us celebrate our countryside and our way of life … celebrate individuality – we all need to be creative and not follow the crowd … let us lead … let us keep our nature intact and not destroy our original habitat ... 

Very fresh vegetables and no doubt fruit

… let us value people, animals, insects, and all things – and then encourage our friends and families to do likewise …




Deniz Bevan of The Girdle of Melian blog - has been writing about The Inklings (literary enthusiasts) ... including Tolkien, C S Lewis ... and others ... in this post there is a lovely description of England in the 1920s ... 



Dappled sun on a woodland ... teeming with
wildlife and bird song ... 
... walking the paths, with very little extraneous noise ... just the scrunch of feet on the ground, insects buzzing ...  keeping the birds chirping their songs for a good birding supper ... then the humans can have another happy discussion over a china tea cup, or a pint in the pub ...

Elephants and Bees Project in Kenya ... and a very Happy Birthday to Lenny tomorrow ...



Who would have thought that that huge pachyderm, the elephant, would be frightened by bees – yet they are. 


A project has been started in Kenya – which by social media (YouTube) has been copied by other conservation projects or local communities which needed to work in conjunction with elephants and people.  In Africa, Sri Lanka and India … the value of social media – here I concur!


Dr Lucy King comes from Eastbourne, but works under the auspices of Oxford University and Disney’s Animal Kingdom in Kenya.  Her project, Save the Elephant, is an innovative study into the use of novel Beehive Fences as a natural elephant deterrent.



Man and animals so often do collide … crop-raiding; or for profit through poaching … a cruel death.  Food is essential to all African farming communities leading to conflict with humans if their crops are trampled or eaten.  How to combat these challenges?


Crop raided farm
The loss in numbers of this huge herbivorous mammal in Africa is frightening; with their status being listed as vulnerable in 2008, while the Asian elephant was endangered … yet numbers continue to be decimated all the time. 


650 elephants were killed in 2012 by Chadian raiders in Bouba D’Njida National Park, Cameroon for their ivory.  A year later another 86 elephants and calves, including pregnant cows, were killed in the same region.


About thirty years ago there were 150,000 elephant in the West African area (Central African Republic, through Chad to Cameroon) … now that figure could be as low as 2,000.  Horrific to consider.


The location of Mwambiti Research area; it is near the Lumo Community Wildlife Sanctuary -
the green lozenge shape - on the edge of the Tsavo National Park and within the lowland
community settlements along the main road across to Mombasa on the Indian Ocean.
The green Park cutting in at top left of the picture is the Serengeti National Park.

Conservationists are always looking for new ways to protect these huge beasts in the areas where a decent elephant population still remains … southern Africa, particularly Kenya … and where they co-habit with humans. 



Dr King explained that they had heard elephants steered clear of bees at their beehives … so after consideration – she and her team in Mwambiti
Dr Lucy King
decided 
on a project to see if this was really true: the elephant were avoiding certain trees that, for example, held a beehive.




A concept of an idea ... 



How and what to do … after research, their novel approach was to build a flimsy fence around an area of a farmer’s land, where crops needed protection, and string ‘beehive boxes’ at certain intervals.


The connective wire (hence the flimsy bit!) – once knocked by the elephant it would rock the bees in their boxes awake – and the elephant would move on.


However improbable it sounds it works … Dr King showed us some remarkable footage … including of an elephant trying to get his leg through the wire – it’s at about a metre high – and then being frustrated, trying again using the other leg … so funny – but so brilliant to see this mammoth walking off in disgust. (Videos and photos are on the website)


Taking the wires used to hang the beehive boxes
between the staves around the farmer's field



Still the huge benefits this work brings to the community – they now have an actual research centre in the locality – visiting dignitaries (Bill Clinton and Chelsea) highlight the Project in other arenas … 




I see an Australian soil scientist has been working there, guiding the locals in ways to improve their land ...

Angelina with some of her honey



… the farmers are able to farm and market their crops, there are other benefits – paying internships, the women folk are involved, harvesting the honey, making candles and lip balm … all bringing in much needed cash into the local community.






Augustine and his team of farmers

Augustine Musyoka, Project Officer at the Elephant and Bees Research Centre, wrote a blog post explaining his role in this conservation work – his passion really comes across in this well-written post.



Also he gives further detail how the mechanics of the whole came about … a fascinating read.


Gathering honey for the community and to sell on
This talk covered passions of mine – Africa, conservation, working with and helping local communities (keeping the villages involved, including the tribal chief), feeding the local population, providing other work, and giving them a place in the world that they can all be proud of: evidenced by all the recognition that the Project is receiving.


Those flimsy wires I mentioned … in Mozambique, the Wildlife volunteers advised they could not use wire … as the poachers would have stolen it by the next day … so they strip tyres down and weave the strips into ‘threads’ to connect the hanging beehives.


 
Gathering the grass into sheaves to use as roofs
over the beehive swings
The fences do not need many beehive boxes along their course … and by trial and error they’ve reduced the quantity so they swing efficiently which see the elephants off, once the buzzing starts!





Hive boxes ready for the community to install

It was a fascinating talk by, Dr Lucy King, a lady who is totally passionate about her work …


Here is the website with its links to the Elephants and BeesProject under the auspices of Save the Elephants.



This is Augustine’s blog post – where he explains all - much better than I do … and you get the added benefit of more photos.  If I was doing more … you’d have to watch a video of me waving my arms around, pointing aimlessly at some very basic stick drawings!

Long line of honey jars .... one of the value added products

One other thing the Project does that may be relatively unusual in today’s world … is that they are happy to share their knowledge for free … so please visit and enjoy.



My god-daughter made a baked bean cake of the Heinz 57
variety for her father's 57th ... I just loved it - I didn't get to
eat any - but the photo is good to go?!
Happy Birthday tomorrow Lenny - it is all 'sweet' ...
but the baked beans look so real.

Lenny - have a very happy week taking things slowly and just enjoying the hugs and love you will be getting from all your amazing friends ... with much love from GrandBlogMom xoxoxoxo


PS - I'm away in the West Country for ten days or so ... so forgive the shortage of acknowledgements ...
