Decades of plant medicine research rarely reach pharmacy shelves

Medicinal Plants
If you've ever wondered why the herbal remedy your grandmother swore by never shows up as a doctor-prescribed medicine, this review explains the exact chain of scientific, business, and policy steps that has to happen first.
A team of Brazilian scientists spent over 40 years studying compounds from native medicinal plants, testing them in labs and occasionally in small clinical trials. They found that even with promising results and one of the richest plant biodiversities on Earth, almost none of these discoveries turn into actual approved medicines you could buy at a pharmacy. The holdup isn't the science, it's that drug companies rarely invest in these projects, clinical trials are hard to run, and government support for long-term plant research keeps drying up.
Key Findings
Over four decades of phytochemical and preclinical research on Brazilian medicinal plants produced extensive scientific data but few translated into registered phytomedicines
Major barriers identified include low pharmaceutical industry engagement, regulatory and operational hurdles for clinical trials, and lack of sustained government funding
Brazil's regulatory framework for phytotherapeutics has evolved but still falls short of supporting evidence-based drug development at scale
chevron_right Technical Summary
A Brazilian research group looks back at 40+ years studying native medicinal plants and finds that even with strong lab science and huge biodiversity, very few of these plants ever become real, approved medicines because of industry, regulatory, and funding gaps.
