One hundred seventy years ago, tuberculosis was a lethal disease. This illness posed a significant threat to humanity, resulting in an estimated 1 billion deaths between 1700 and 1900. Notably, traces of tuberculosis have been found in the mummies of ancient Egyptian kings. In the late 1840s, German botanist Hermann Brehmer, confronted with the fatality of tuberculosis, relocated to the Himalayas in search of fresh air. Remarkably, he survived and is believed to have successfully fought off Mycobacterium tuberculosis in that less favorable environment for bacterial growth. As a result, numerous nursing homes emerged across Europe and the United States, including specialized facilities for tuberculosis care and luxury accommodations for the affluent. However, by the 1940s, many of these nursing homes began closing due to the emergence of antibiotics, which drastically changed their economic viability. Throughout history, it seems that economic value often proves transient. - Joseph’s “j...

The plum contains a poison called “amygdalin.” This poison is found not only in plums but also in other drupes. The poison “amygdalin” is a combination of two glucose molecules. When these glucose molecules are divided, they turn into “prunasin,” which is more prevalent in other plants. When an insect attacks a plant, it breaks the bond with glucose, turning it into “mandelonitrile” and quickly converting it into “benzaldehyde” and “hydrocyanic acid (HCN)” once more. HCN is a respiratory poison, and benzaldehyde is a unique fragrance component of cherries, bitter almonds, and pistachios. This dangerous ingredient is also present in green tea, but it appears only in small amounts, so it does not cause any problems when consumed. It is an ironic phenomenon in which by-products essential for survival kill other living beings. - Joseph’s “just my thoughts”
