Description
The study demonstrates hippocampal molecular changes after oral honey administration but doesn’t address bioavailability or brain penetration of active compounds. This pharmacokinetic gap is critical for understanding therapeutic feasibility and optimal dosing strategies.
Gap type: unexplained_observation Source paper: Phytoconstituents of Indian mustard honey impart antidepressant activity in reserpine-induced depressed condition through activation of TrkB/CREB/BDNF pathway in hippocampus. (2026, Nutritional neuroscience, PMID:41017663)
