Artemisia annua L. leaf

13

Artemisia annuua L.The plant can grown in many places but it may notcontain artemisinin. For example: Visitors of the ancientpalaces in the forbidden city in beijing can find niceartemisia annua plants pushing left and right as weeds,but these plants do not contain artemisinin

14

Artemisia annua L.

but a clone from China could contain up to 1.1 % artemisinin

The average artemisinin concentration in plants of European origin range from 0.03 to 0.22 % (dry leaves weight basis) artemisinin,

Artemisinin and derivativesThere is a fear that improper use of artemisinin and its

derivatives will spur the malaria parasite to evolve to

resist treatment with the compounds, something that has

happened to all previous malaria therapies

Natural Mosquito Repellents

*It is ten times more effective than DEET at repelling mosquitoes

Agastache cana (Hook.) Woot. & Standl.

Azadirachta indica Juss f.

Cymbopogon nardus (L.) Rendle

Melissa officinalis L.

Nepeta cataria L.*

Pelargonium citrosum Vanleenii

If you think you're too small tobe effective, you have never been in

bed with a mosquito!

27

Thank you for your attention!

Is it acceptable that an African child dies of malaria every 30 seconds when safe and effective treatment is available.
