Review on enhancing henna harvesting: Addressing manual labor challenges

Henna (Lawsonia inermis L.) is a perennial plant that is widely used in traditional medicine and its potential for broader therapeutic applications. It is known for its resilience in drought-prone areas and minimal water requirements, which makes it a valuable opportunity for farmers in semi-arid regions of India to boost their incomes. The plant is rich in bioactive compounds, including carbohydrates, proteins, flavonoids, phenolic compounds, alkaloids, tannins, xanthones, and terpenoids, and its diverse range of pharmacological properties underscores the plant's significance in traditional medicinal and industrial domains, with a productive lifespan extending up to 25 years. Despite its importance, there is limited information on the design and development of specialized henna harvesting machines. This review focuses on the challenges associated with manual harvesting, such as musculoskeletal disorders, physical fatigue, and physical toll on workers. Moreover, it addresses the risks of injuries related to manual handling, reducing the incidence of injuries, and decreasing labor costs. This technological advancement would ultimately lead to a more streamlined, productive, and profitable harvesting process.
