Phytophotodermatitis and the effects of parthenium plants in india: a comprehensive review

Phytophotodermatitis is a skin condition that results when certain plant chemicals interact with sunlight, leading to dermatitis upon exposure. Parthenium hysterophorus, also referred to as Congress grass, is a growing concern in India due to its plethora of hazards to the environment, including its toxicity to livestock and its invasive nature, which disturbs the biodiversity and agricultural productivity and health-related threats which include severe allergic reactions, contact dermatitis, and triggering respiratory diseases such as allergic rhinitis and even asthma. This plant is invasive as well as contains phototoxic compounds, especially psoralens, which can trigger dermatitis following exposure to ultraviolet (UV) light in individuals who are sensitized. Clinical features in affected patients range from erythema, blisters, and changes in pigmentation of the skin, and especially impacts those who get exposed to the plant, primarily involving agricultural activities or outdoors. There is an increase in incidence of phytophotodermatitis secondary to Parthenium, which highlights the need for intensified public awareness and plan of action. The general public needs to be made aware of the risks that are linked to Parthenium exposure and reforms regarding the same need to be implemented. Given the invasiveness of this plant species, policies to control its spread in the region are needed. This article brings into limelight the necessity of further research in the fields of environmental, socio-economic, and clinical outcomes and prevention of Parthenium in India. Public health education and constructive management practices is indispensable to alleviate the risks posed by Parthenium.
