Earth apple
Helianthus tuberosus
Helianthus tuberosus, commonly known as Jerusalem artichoke, is a traditional plant native to North America. It has been traditionally used for food and as a source of inulin but lacks specific recorded medicinal uses across various traditions. Scientific evidence suggests that Jerusalem artichoke contains high levels of inulin and exhibits superior antifungal activity, particularly against Fusarium mycelial growth. In field trials, optimizing the use of vermicompost with mineral fertilizer can enhance its inulin content and tuber dry weight, though results may vary by genotype. Ultrasound-assisted extraction methods have been shown to yield up to 69.25% inulin and exhibit dose-dependent antibacterial activity against selected pathogens. No major safety concerns or drug interactions have been recorded for this plant.

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.
