Yartsa gunbu has been used as a traditional remedy for thousands of years, though only by the very wealthy.
冬蟲夏草被用作傳統(tǒng)藥物已經(jīng)上千年，但僅限于非常富有的人群。
It's been bartered for tea and silk, and is worth more than four times its weight in silver.
它被用來交換茶葉和絲綢，可以換回超過本身四倍重量的銀子。
So lucrative is this trade, that sites and information are jealously guarded.
這項(xiàng)貿(mào)易是如此的暴利使得它的交易地點(diǎn)和信息都被謹(jǐn)慎地保護(hù)起來。
At the nearby market, yartsa gunbu are cleaned, and their true nature becomes clear. The yartsa gunbu translates as "summer grass, winter worm".
在附近的集市上冬蟲夏草被清理干凈，這使得它的本來面目顯露了出來，冬蟲夏草被翻譯為“冬天的蟲子夏天的草”。
The winter worm is a caterpillar. It eats roots of grasses in preparation for its transformation into a moth.
冬蟲是一種毛蟲，它以草根為食，為自己變身成蛾做準(zhǔn)備。
But some winter worms never make it as moths. Instead, a strange growth erupts from their body, appearing above ground in summer. This is the "summer grass",a fungus called Cordyceps, whose spores have infected the caterpillar, using its body as their host.
但有些冬蟲卻從沒有機(jī)會變成蛾。而在夏季一個奇怪的植物，在冬蟲的體內(nèi)生長發(fā)育直至破土而出，這就是“夏草”。一種被稱為蟲草的真菌，是它的孢子侵入了毛蟲體內(nèi)，并將毛蟲的身體作為它們的宿主。
Modern scientific tests have shown that substances contained in Cordyceps lower blood pressure and make it easier to breathe.
現(xiàn)代科學(xué)實(shí)驗(yàn)證明含有冬蟲夏草的物質(zhì)可以降低血壓并能使呼吸更順暢。
So in recent years, harvesting this natural treasure has grown into a huge and profitable business.
所以近些年來收獲這種自然資源，已經(jīng)成為有巨大利益的生意。
