Studies
Occupational Contact Dermatitis / Low Allergenic Potential:
The allergenic potential of golden shrimp plant is probably low, requiring prolonged contact for sensitization, more likely to occur in greenhouse gardeners handling potted plants rather than outdoor gardeners tending landscape plants.   (1)
Antibacterial Testing / No Effect: Study of Golden Shrimp Plant for antibacterial property showed no activity against Staphylococcus aureus and Escherichia coli. The study author suggests the ethanol extraction exterminated the tannins which is responsible for antibacterial property of many plants. (4)
