My Journey with Medicinal Mushrooms

People often ask me where my love for medicinal mushrooms began.

For me, it began in 1991 when I joined the National Research Centre (NRC) in Cairo, Egypt, as a Research Assistant. Whenever I hear the phrase “Love, Where It Began,” I think of those early days when a simple scientific question captured my imagination and ultimately shaped my life’s work:

Can mushrooms help fight cancer?

One of the first scientific papers that truly inspired me was the pioneering work of Goro Chihara on lentinan, the anticancer polysaccharide isolated from the Shiitake mushroom, Shiitake. Reading about the discovery of lentinan in the 1970s opened a new world for me. It showed that mushrooms were not simply food—they contained biologically active compounds capable of influencing the immune system and potentially helping cancer patients.

I became fascinated not only by the biological activity of mushroom β-glucans but also by their structure. During my early research years, I even built a physical model illustrating the triple-helical structure of β-glucans based on X-ray crystallography studies. Holding that model in my hands made the science come alive and strengthened my conviction that understanding molecular structure was essential to understanding biological function.

Through scientific collaborations, I received numerous research papers from Japan describing the anticancer and immune-modulating properties of medicinal mushrooms. Those papers inspired me to dedicate my career to this field.

That passion led me to complete both my Master’s degree and PhD focusing on the anticancer potential of medicinal mushrooms. My research expanded into mushroom biotechnology, β-glucans, immune modulation, and cancer-related applications.

What began as a scientific curiosity eventually became a lifelong mission. I established my own research school, mentored graduate students, published scientific papers, and obtained patents related to medicinal mushroom biotechnology and anticancer applications. Watching former students become successful scientists has been one of my greatest rewards.

Today, more than three decades later, I continue to serve as a researcher, educator, inventor, consultant, and international keynote speaker in the field of medicinal mushrooms. Yet I still remember that young Research Assistant in Cairo reading those early Japanese papers and wondering whether mushrooms could help fight cancer.

That was where the research began.

That was where the dream began.

And that was where the love began.
