How to pronounce "malaria"

and Africa loses about 13 billion dollars a year because of malaria.

And so as people get healthier, they also get wealthier.

The first one is called Advanced Bio-Extracts Limited.

It's a company built in Kenya about seven years ago

by an incredible entrepreneur named Patrick Henfrey and his three colleagues.

These are old-hand farmers

who've gone through all the agricultural ups and downs

in Kenya over the last 30 years.

Now, this plant is an Artemisia plant;

it's the basic component for artemisinin,

which is the best-known treatment for malaria.

It's indigenous to China and the Far East,

but given that the prevalence of malaria is here in Africa,

Patrick and his colleagues said, "Let's bring it here,

because it's a high value-add product."

The farmers get three to four times the yields that they would with maize.

And so, using patient capital -- money that they could raise early on,

that actually got below market returns

and was willing to go the long haul and be combined

with management assistance, strategic assistance --

they've now created a company where they purchase from 7,500 farmers.
