Zebrafish models for the evaluation of essential oils (EOs): A comprehensive review
Summary
This comprehensive review examines how zebrafish models have been used to evaluate the biological effects and safety of essential oils derived from aromatic plants. Researchers summarize findings on toxicity screening as well as beneficial activities including antioxidant, anti-inflammatory, and neuromodulatory effects. The study concludes that zebrafish offer a valuable, cost-effective model for accelerating the identification and quality assessment of essential oils with potential health applications.
Essential oils (EOs) derived from crops, especially aromatic plants, have been well-acknowledged to provide several health benefits for humans. Zebrafish as an unprecedented tool has been widely used as an excellent vertebrate model in labs owing to its many useful characteristics. Its applications for rapidly and economically screening and identifying toxicity, safety, and bioactivity of EOs may serve to meet the rising demand for nutraceuticals, food supplements, and natural cosmetics. In this study, we summarized the research progress of zebrafish models in evaluating EOs. In addition, toxicity, safety, and various bioactivities of EOs were summarized using a wide variety of readily applicable zebrafish models covering antioxidant, anti-inflammatory, angiogenesis inhibition, neuromodulation, anesthesia, anti-melanogenesis, analgesic activities, etc. In conclusion, zebrafish is a valuable animal model for evaluating the bioactivity and safety of EOs, and using such a model may contribute to speeding up the identification of novel EOs with potential health functions and quality assessment, which in turn boosts the recognition of aromatic plants as important industrial crops and encourages a healthier way of life.

The endocannabinoid system in zebrafish and its potential to study the effects of Cannabis in humans
Researchers reviewed how zebrafish — a small freshwater fish widely used in medical research — can serve as a model for studying how cannabis compounds interact with the body's endocannabinoid system, the network of receptors involved in pain, mood, and immune function. Zebrafish share many biological similarities with humans and allow faster, lower-cost studies than mammalian models, making them useful for testing potential cannabis-based therapies.
