Okinawa spinach
Gynura bicolor
Gynura bicolor, a plant traditionally used in various Asian countries for its purported health benefits, has not been extensively documented in traditional medicine. Scientific evidence suggests that extracts rich in flavonoids from Gynura bicolor may exhibit antimicrobial activity against certain Vibrio species affecting shrimp. Additionally, the identification of novel viruses such as gynura bicolor carlavirus (GbCV) and a maculavirus in these plants highlights their potential role in viral studies. Dihydrocaffeic acid from Gynura bicolor has shown protective effects against 5-fluorouracil-induced intestinal mucositis, indicating possible anti-inflammatory and antioxidant properties. No significant safety concerns or known drug interactions have been reported for this plant.

What the science says
- Plant extracts, particularly those rich in flavonoids, showed promising antimicrobial activity against Vibrio parahaemolyticus and Vibrio alginolyticus in whiteleg shrimp.
- A putative novel carlavirus, provisionally named gynura bicolor carlavirus (GbCV), was identified in Gynura bicolor plants showing mosaic and chlorosis symptoms in China.
- This study identified a new strain of vanilla distortion mosaic virus and a novel maculavirus in Gynura bicolor using high-throughput sequencing and molecular techniques.
- Dihydrocaffeic acid from Gynura bicolor showed protective effects against 5-fluorouracil-induced intestinal mucositis by suppressing inflammation and alleviating oxidative stress.
