It is known that plague epidemics and pandemics spread both by sea and by land. However, in the 16th century an entire "hidden face" of the continent was discovered and opened thanks to the Portuguese. It is noteworthy that just as Francis I or the Dutch, Yersinia pestis did not respect the longitudinal limits set out by the treaties of Tordessillas and Saragossa. Even before the arrival of Vasco de Gama in Goa and all the way to the settling of the Moluques in Macao, Canton and Kagoshima, one can follow the progression of at least ten or so epidemics against a general epidemic back drop, thanks especially to the works of Jose de Vasconcellos e Menezes as well as some others. Scurvy was, as far as plague was concerned, a regulating factor, at least to a certain extent.

Sesuvium portulacastrum has long been used as a remedy for fever and scurvy. Hydrodistillation was used to extract the essential oil from the fresh leaves of Sesuvium portulacastrum. The essential oil yield obtained was 0.15%. Using GC-MS analysis, alpha-pinene, camphene, beta-pinene, alpha-terpinene, O-cymene, limonene, 1,8-cineole, alpha-terpinene, bornyl acetate, tridecane, trans-caryophyllene and alpha-humulene were identified. The hole plate diffusion method was used for antibacterial testing. The essential oil exhibited antibacterial activity against Acetobacter calcoacetica, Bacillus subtillis, Clostridium sporogenes, Clostridium perfringens, Escherichia coli, Salmonella typhii, Staphylococcus aureus and Yersinia enterocolitica. The mycelium growth inhibition method was used for the antifungal testing. The oil exhibited antifungal activity against Candida albicans, Aspergillus niger, Aspergillus flavus and Penicillium notatum. Using the beta-carotene, acetone and linoleic acid method for the antioxidant testing, the essential oil showed antioxidant activity threshold of 15.9 mm mean zone of color retention.
