Traditional medicine and research

Long peppers have been used in Ayurveda and traditional Chinese medicine as a treatment.^[3][4]

Targtex, a biotechnology spin-off of the Portuguese Institute for Molecular Biology, developed a piperlongumine hydrogel that is to be applied after the removal of Glioblastoma tumours, with the goal of neutralizing remaining cancer cells. The hydrogel was effective in laboratory and animal studies and is scheduled for Phase I human clinical trials sometime in 2023.^[5][6]
