I moved to Argentina, then back to Tokyo and then to Anchorage, in Alaska, where I ran a restaurant. After 50 days the restaurant burnt down – an electrical fire. I lost my dream. I lost my money. I lost my passion. I thought about suicide, but thinking of my family and my kids made me realise I had to wake up.

everyone saw me as a victim of a terrible illness. But what happened to my body was far less frightening than what happened to my soul. The stroke wiped out my faith. It took me so far from my guru that I felt my oxygen cord had been cut. ... I couldn't put the two together. Then I thought, maybe the stroke is a form of grace, and I hunted for that: how could the stroke be seen as grace? ... The stroke was giving me lessons, advanced lessons. ... It brought me into my soul, and that's grace.

I don’t think I could. Of course I’m saying this on American soil. I’m facing a few more months of work in this city, but at the end of it, I will be returning to South Africa. I would like to believe that if for some reason the situation deteriorated to the point where I was told, “If you leave South Africa, you can never come back,” I’d stay there. There were periods in my life when I could have been seduced away. I am incredibly fortunate that the government took away my passport at the point when I was most open to seduction. With my passport gone, I could have left on a one-way ticket. But the issue was so starkly highlighted that I had no problem in saying, “No.”

I had two options. One was to remain silent and wait to be killed. And the second was to speak up and then be killed. I chose the second one. I decided to speak up.

Most pharmaceutical workshops were shut down during the great cultural revolution. Without manufacturing support, we had to extract herbs ourselves using household vats etc. The team worked very long hours every day including the weekends. Due to lack of proper equipment and ventilation, and long-term exposure to the organic solvents, some of my team members included myself started to show unhealthy symptoms. This, however, did not stop our efforts.

In Ge Hong's A Handbook of Prescriptions for Emergencies (肘后备急方), I noticed one sentence "A handful of Qinghao immersed in two liters of water, wring out the juice and drink it all" (青蒿一握, 以水二升渍, 绞取汁, 尽服之) when Qinghao was mentioned for alleviating malaria fevers. Most herbs were typically boiled in water and made into a decoction before taken by the patients. This unique way of using Qinghao gave me the idea that heating during extraction might have destroyed the active components and the high temperature might need to be avoided in order to preserve the herb's activity.
