One way to counter this worldwide issue would be to stop the transmission such as through disinfectants, however most of the poverty-stricken population cannot afford their costs. Because of the latter, they tend to rely on ethnomedicine. To do this, they find herbal and natural plants that can prevent the spread of infectious diseases, with the cucumber tree fruit being one of the plants being used for the aforementioned purpose, most likely for its prevalence in the Philippines. Cucumber tree fruit, or better known as kamias or bilimbi in the Tagalog language, is a yellowish-green and highly acidic fruit commonly found in Southeast Asian countries such as Malaysia, Indonesia, and the Philippines. It also has a few relations between the star fruit; the difference being its sour flavor. It is a natural source of vitamins B and C, iron, phosphorus and antioxidants. Even if it is not as familiar as other tropical fruits, it has beneficial properties.According to a study related to the phytochemical properties of the cucumber tree fruit, its chloroform and methanol fruit extracts were active against different kinds of pathogenic bacteria (Wahab et. al, 2009). In another study, the oxalic acid of the cucumber tree fruit has an effect on particular species of bacteria such as S. aureus (Sripanidkulchai et. al, 2002), however, another study found that an overdose of oxalic acid can cause acute kidney failure, caused by increased serum oxalate level and accumulation of calcium oxalate crystals in renal tubules (Alhassan and Ahmed, 2016). A research related to the antimicrobial properties of underutilized fruits of Malaysia (cucumber tree fruit being one of them) concluded that any part of the cucumber tree fruit has an antimicrobial activity against wide range of gram-positive and gram-negative bacteria, meaning that the extermination of most helpful bacteria can occur (Aziz, 2016).
Overall, various studies have proven the cucumber tree fruit to be antimicrobial, anti-inflammatory, and antibacterial. With the aforementioned properties of the cucumber tree fruit, along with its availability, it can be easily used for medication purposes. The antimicrobial properties of the cucumber tree fruit can be utilized into a disinfectant for the removal of pathogenic bacteria and the prevention of transmission of diseases, especially those that are transferred through physical contact. The researchers purpose is to formulate an affordable disinfectant that can be afforded by anyone, even by the poor, and to provide another substitute to household disinfectants, which can contain chemicals that could negatively affect on a person’s health.
