That's a scientist who works in the rainforest to document how people use local plants.  我在热带雨林工作，记录人们如何使用当地植物。

I've been doing this for a long time,  我做这项工作很久了，

and I want to tell you,  我可以告诉大家，

these people know these forests and these medicinal treasures better than we do and better than we ever will. 这些人对当地森林和里面医药珍宝的了的比我们多得多，永远多得多。

But also, these cultures, these indigenous cultures, 但是，这些文化，这些土著文化，

are disappearing much faster than the forests themselves.  消失得比森林还快。

And the greatest and most endangered species in the Amazon Rainforest is not the jaguar,  在亚马逊热带雨林中，最伟大而最濒危的物种不是美洲豹，

it's not the harpy eagle,it's the isolated and uncontacted tribes.  也不是美洲角雕，而是与世隔绝的人类部落。

Now four years ago, I injured my foot in a climbing accident and I went to the doctor.  四年前，我在爬山时伤了脚，我去看医生。

She gave me heat,  她给我进行热疗，

she gave me cold, aspirin,  进行冰疗，用阿司匹林，

narcotic painkillers, anti-inflammatories,  用麻醉止痛剂，抗炎药，

cortisone shots.  注射可的松。

It didn't work.  没有疗效。

Several months later,  几个月后，

I was in the northeast Amazon,  我在亚马逊东北部，

walked into a village,  我走进一个村落，

and the shaman said, You're limping.  萨满说，你跛了。

And I'll never forget this as long as I live.  这一幕我一生都不会忘记。

He looked me in the face and he said, Take off your shoe and give me your machete. 他看着我的脸，对我说，脱鞋，把你的砍刀给我。

He walked over to a palm tree and carved off a fern,  他走向一棵棕榈树，切下来一片蕨，

threw it in the fire,  扔到火里，

applied it to my foot,  然后敷在我脚上，

threw it in a pot of water,  然后又扔进了一壶水中，

and had me drink the tea.  让我把那个当茶喝了。

The pain disappeared for seven months.  整整七个月，我再也没疼过。

When it came back, I went to see the shaman again.  复发后，我又去见萨满。

He gave me the same treatment,and I've been cured for three years now. 他对我进行同样的疗法，现在我已经痊愈三年了。

Who would you rather be treated by?  你想让谁给你治病？

Now, make no mistake a Western medicine is the most successful system of healing ever devised,  别误会西医是人类发明的最成功的医疗体系，

but there's plenty of holes in it.  但它也有缺陷。

Where's the cure for breast cancer?  乳腺癌的疗法在哪里？

Where's the cure for schizophrenia?  神经分裂症的疗法在哪里？

Where's the cure for acid reflux?  胃酸倒流的疗法在哪里？

Where's the cure for insomnia?  失眠症的疗法在哪里？

The fact is that these people can sometimes, sometimes, sometimes cure things we cannot.  事实是，这些土著人在有些时候，能治疗我们治不了的病。
