“…Previous studies reported several biological properties of AGO on anti-bacterial, anti-oxidant, and anti-inflammatory activities [ 2 – 5 ]. Interestingly, we have recently found that AGO has excellent action on fish anesthesia [ 6 ]. However, the poor water miscibility of AGO causes limitations in its application, particularly in animals for which water is the essential environment, such as fish.…”

Alpinia galanga oil (AGO) possesses various activities but low aqueous solubility limits its application particularly in aquatic animals. AGO has powerful activity on fish anesthesia. Ethanol used for enhancing water miscible of AGO always shows severe side effects on fish. The present study explores the development of self-microemulsifying drug delivery systems (SMEDDS) and nanoemulsions (NE) to deliver AGO for fish anesthesia with less or no alcohol. Pseudoternary phase diagrams were constructed to identify the best SMEDDS-AGO formulation, whereas NE-AGO were developed by means of high-energy emulsification. The mean droplet size of the best SMEDDS-AGO was 82 ± 0.5 nm whereas that of NE-AGO was 48 ± 1.6 nm. The anesthetic effect of the developed SMEDDS-AGO and NE-AGO in koi (Cyprinus carpio) was evaluated and compared with AGO ethanolic solution (EtOH-AGO). It was found that the time of induction the fish to reach the surgical stage of anesthesia was dose dependent. NE-AGO showed significantly higher activity than SMEDDS-AGO and EtOH-AGO, respectively. EtOH-AGO caused unwanted hyperactivity in the fish. This side effect did not occur in the fish anesthetized with SMEDDS-AGO and NE-AGO. In conclusion, SMEDDS and NE are promising delivery systems for AGO.

“…Alpinia galanga essential oil extract anaesthetic effect on O. niloticus showed constant value of glucose and cortisol levels when compared with the fish exposed to MS‐222 which showed higher levels (Pikulkaew et al., 2017 ). A. triphylla essential oil at 300 μL L −1 concentration reduced cortisol levels in anaesthetized O. niloticus juveniles (Teixeira et al., 2017 ).…”

BackgroundUsing anaesthetics is an important application in aquaculture especially where the fish transportation, vaccination, grading, sorting activities and many other handling operations have been conducted during the different stages of production periods in the farms or hatcheries.ObjectivesThis study aimed to evaluate the efficacy of oregano essential oil (OO) as an anaesthetic for Nile tilapia and to determine the optimal concentration and post‐application stress effects compared to clove oil (CO).MethodsNile tilapia juveniles were exposed to different concentrations of OO (20–40–60–80–100 mg L−1) and CO (50 mg L−1) for different time periods to determine the optimal concentration and exposure time. After the effective concentration of OO was determined, in the second experiment, stress parameters (glucose, plasma cortisol) were analysed after 0, 2, 6, 12 and 24 h of application. The results compared to the control group and CO results.ResultsThe study found that OO which has carvacrol compound higher than 78% was an efficient anaesthetic for Nile tilapia, and the effective concentration was found to be 60 mg L−1. No significant differences were found between opercular beats in any concentration of OO and CO. Basal glucose level in blood without anaesthesia application and recorded at 39.33 mg dL−1 and significantly lower than OO and CO at first two sampling points, 0 and 2 h (p < 0.05). According to plasma cortisol level results, although CO experimental group showed secondary stress response at 12 h (17.91 ± 4.21 ng mL−1), OO and CO group cortisol levels decreased at 24 h after anaesthesia application 7.13 ± 0.14and 7.01 ± 0.54 ng mL−1, respectively, below the control group cortisol concentration (12.28 ± 1.81 ng mL−1).ConclusionsThese findings have important implications for the aquaculture industry as the use of OO as an anaesthetic could reduce the stress and mortality associated with traditional anaesthetics. Further research is needed to evaluate the efficacy of OO as an anaesthetic agent for other fish species and to determine the optimal concentration and exposure time for different species.

Arthritic inflammation of joints affects people of all age groups. The treatment is a challenge as arthritis is a complex disease and evolves over years. Patients often have to take medicines for the rest of their life. Commonly prescribed medicines like analgesic, glucocorticoids and non-steroidal anti-inflammatory drugs have side effects. The new disease-modifying medicines are costly. People in the healthcare system are assessing the dynamics of complementary and alternative medicines. One such remedy is Alpinia galanga (AG) of Zingiberaceae family. It is characterized by the presence of rhizome, wide leaves and terminal inflorescence. The references for its medicinal uses are found in traditional medicines. It is cultivated in tropical regions of south east Asia. Its rhizome is highly aromatic and most frequently used as a food and medicine. The various extracts of AG are prepared by the researchers and studied for its phytoconstituents and pharmacological activities. Clinical, in vitro, in vivo and in silico experimentation techniques are used to validate the claims for various therapeutic activities. This article focuses on reviewing literature to ascertain the anti-arthritic potential of AG. The article has been divided in 2 parts and includes analgesic, anti-arthritic, anti-inflammatory, antioxidant, other therapeutic effects as well as safety and toxicity of AG.
