Earth apple
Helianthus tuberosus
Helianthus tuberosus, commonly known as Jerusalem artichoke, is a plant species utilized within various traditional medicine systems. It has been historically applied for purposes including diabetes, rheumatism, diuretic, and stomachic effects, as well as for its potential androgenic, aperient, cholagogue, and spermatogenic properties. Scientific evidence suggests the plant is a significant source of inulin and demonstrates some antifungal and antibacterial activity against specific pathogens in controlled settings. There are currently no major safety issues or notable drug interactions recorded in the available data.

What the science says
- Jerusalem artichoke (Helianthus tuberosus) exhibited the highest inulin content among tested samples.
- Helianthus tuberosus extract showed superior antifungal activity, inhibiting Fusarium mycelial growth and reducing stem base disease severity in greenhouse conditions.
- Integrating 12.5 ton ha⁻¹ vermicompost with half the recommended mineral fertilizer significantly improved inulin content and tuber dry weight in Jerusalem artichoke, though results varied by genotype.
- This study optimized ultrasound-assisted extraction conditions for inulin from Jerusalem artichoke, achieving up to 69.25% yield and demonstrating dose-dependent antibacterial activity against selected pathogens.
