Billions of Cockroaches Are Bred in China to Create a ‘Healing Potion’
Insectophobes would probably agree that any place that breeds billions of cockroaches a year is akin to hell on Earth.
That place actually exists—in the Sichuan Province city of Xichang—but China's government says it's all for a good cause. The indoor farm is tasked with breeding 6 billion creepy-crawlies a year to meet the country's demand for a special "healing potion" whose main ingredient is ground-up roaches.
While there are other cockroach breeding facilities in China that serve the same purpose, the one in Xichang is the world's largest, with a building "the size of two sports fields," according to the South China Morning Post.
The facility is reportedly dark, humid, and fully sealed, with cockroaches given the freedom to roam and reproduce as they please. If, for any odd reason, someone should want to visit the facility, they'd have to swap out their day clothes for a sanitized suit to avoid bringing pollutants or pathogens into the environment, according to Guangming Daily, a government newspaper.
The newspaper article contains a strangely poetic description of the cockroach farm:
"There were very few human beings in the facility. Hold your breath and (you) only hear a rustling sound. Whenever flashlights swept, the cockroaches fled. Wherever the beam landed, there was a sound like wind blowing through leaves. It was just like standing in the depths of a bamboo forest in late autumn."
Less poetic, though, is the description of how the "miracle" potion is made. Once the bugs reach maturity, they are fed into machines and ground up into a cockroach paste. The potion claims to work wonders for stomach pain and gastric ailments, and according to its packaging, it has a "slightly sweet" taste and a "slightly fishy smell."
The provincial government claims that the potion has healed more than 40 million patients, and that the Xichang farm is selling its product to more than 4000 hospitals throughout China. While this may seem slightly off-putting, cockroaches have been used in traditional Chinese medicine for thousands of years.
Some studies seem to support the potential nutritional benefit of cockroaches. The BBC reported on the discovery that cockroaches produce their own antibiotics, prompting scientists to question whether they could be used in drugs to help eliminate bacterial infections such as E. coli and MRSA.
In 2016, scientists in Bangalore, India, discovered that the guts of one particular species of cockroach contain milk protein crystals that appear to be nutritious, TIME reports. They said the milk crystal could potentially be used as a protein supplement for human consumption, as it packs more than three times the energy of dairy milk.
"I could see them in protein drinks," Subramanian Ramaswamy, a biochemist who led the study, told The Washington Post.
However, as research has been limited, it's unlikely that Americans will start to see cockroach smoothies at their local juice bar anytime soon.
