Due to increasing participation in outdoor activities, many people visit the emergency room for various symptoms after mistaking poisonous plants for medicinal herbs. The toxicity of Arisaematis rhizome is due to its content of calcium oxalate, which causes painful oropharyngeal edema, hypersalivation, aphonia, oral ulceration, esophageal erosion, and hypocalcemia. We report a case of accidental poisoning after chewing and spitting of the root of A. rhizome, resulting in focal symptoms-such as oral pain, swelling and drooling-that required only conservative management. A 54-year-old male and his 58-year-old wife developed oral pain, swelling and drooling after accidentally chewing and spitting the root of the A. rhizome plant as a medicinal herb. Their symptoms started immediately after chewing on and spitting out the root of A. rhizome, and they were unable to speak due to oral pain, swelling, and hypersalivation on arrival at the emergency department. They were treated with antihistamines and corticosteroids and painkillers. A few hours after treatment, they had improved and were discharged from the hospital.

Objective: Farmers are known to have high prevalence of asthma and chronic obstructive pulmonary disease(COPD). This study aims to investigate the current status of asthma and COPD in domestic and foreign farmers with the ultimate goal of raising awareness of asthma and COPD among farmers and contribute to supporting evidence for the prevention of respiratory diseases in farmers. Methods: The study utilized data from the "Farmer’s Occupational Disease Survey," conducted by the Rural Development Administration, to determine the prevalence of respiratory diseases in domestic farmers.The prevalence of asthma and COPD in overseas farmers was evaluated by researching other foreign studies and articles. Results: The prevalence of asthma and COPD in domestic farmers was less than of foreign farmers’.The prevalence of asthma in domestic farmers was high as upto 8.4% and COPD upto 5.5%. Studies from Europe and America showed prevalence of asthma in farmers high as upto 14.8% and COPD upto 17.1%. Conclusions This study conducted an investigation using the 'Survey on Occupational Diseases and Injuries in Farmers to understand the current status of asthma and COPD in domestic farmers. Due to a lack of relevant domestic research, we examined and compared with the research results on asthma and COPD among overseas farmers. Further research is necessary and preventive measures for respiratory diseases need to be developed.
