Lettuce water
Pistia stratiotes
Pistia stratiotes, commonly known as water lettuce, is a floating aquatic plant traditionally found in various water bodies. Its traditional uses are not well-documented, though it has been observed to play a role in local ecosystems and water management practices. Scientific evidence suggests that Pistia stratiotes may influence the growth of lettuce plants under soilless conditions, enhancing their nutritional quality when associated with specific bacteria. However, the broader implications for its use as a medicinal or agricultural aid remain inconclusive due to limited research. Studies have also noted that environmental stressors, particularly nutrient-poor (NP) conditions, can affect Pistia stratiotes' photosynthetic capabilities, which could be mitigated by selenium intervention. No significant safety concerns or known drug interactions with Pistia stratiotes have been reported in the literature.

What the science says
- Lettuce grown under soilless conditions showed enhanced growth and nutritional quality when inoculated with bacteria associated with the roots of Pistia stratiotes, Eichhornia crassipes, and Alternanthera philoxeroides.
- The study found that both the frequency and extent of aquatic plant management, particularly with herbicides, can negatively impact native plant communities in waterbodies.
- Pistia stratiotes was recorded at 49.3% of surveyed sites along the Élővíz Canal system, with reproductive plants found but their role as invasion hubs not explicitly tested.
- NP stress reduced photosynthetic pigments and inhibited photosystem function in P. stratiotes, which was alleviated by Se intervention.
