“…Solar box treatment was more effective in the restoration of ash content in Z. officinale compared to sun oven plus solar box, and conventional oven drying at 50 °C as well as microwave oven drying treatments (37). On the other hand, C. domestica, Bonga51/71 variety treated with conventional curing and solar tunnel dryer had the highest total ash content, while the lowest ash content was observed in the Dame variety cured in improved curing and drying methods in greenhouse solar dryer (42). On the contrary, the ash contents showed no significant variations in C. longa rhizome samples with various oven drying temperatures, viz.…”

“…Again, the flat-bed drying treatment at temperatures of 50, 60, and 70 °C, conducted on C. longa showed the retention of the highest curcumin content at 50 °C (47). On the other hand, the Bonga 51/71 variety of C. domestica, when cured with conventional curing and drying with a solar tunnel dryer, resulted in the highest retention of curcumin content (42). Interestingly, the cooked/oven-dried and sun-dried samples of C. longa exhibited the highest curcumin content, with no significant difference between the two treatments, while the blanched/oven-dried and oven-dried samples showed the lowest curcumin content with no significant difference between the two treatments (35).…”

Curcuma caesia Roxb. of the Zingiberaceae family, is an ethnobotanically important rhizomatous perennial herb and is commonly known as “Black turmeric”. Like in other species of Curcuma, the pharmacologically important polyphenol curcumin is also found in C. caesia. In traditional medicine, C. caesia has been used to treat piles, leprosy, asthma, cancer, diabetes, fertility, toothache, vomiting, allergies, etc. Drying is considered the simplest and most cost-effective means of preserving raw plant materials, safeguarding the integrity of nearly all biologically active substances. Medicinal plant materials are primarily utilized in their dried forms in pharmaceutical industries. However, it has been observed that there is a lack of comprehensive information on the effects of different drying methods on quality parameters, and other pharmaceutically important aspects of C. caesia. Hence, here, we investigated the impact of various drying methods, such as direct sunlight exposure, solar drying, shade drying, and conventional oven drying with or without previous boiling, on the quality parameters of C. caesia rhizome, such as moisture, ash, and curcumin content. The results suggest that oven drying at 100 ?C, despite possessing favorable criteria for drug designing like the smallest particle sizes and the lowest moisture content, did not restore the maximum level of ash, curcumin, and essential mineral elements. Nevertheless, boiling in the range of 60 ?C – 80 ?C for 30 minutes before drying restores the pharmaceutically important qualities more favorably. The results of this study will help to formulate better treatment for restoring the market-preferable optimum quality of C. caesia.

“…These results suggest that supplementation with curcumin is able to improve the action of selective serotonin reuptake inhibitor class of antidepressants, such as escitalopram, mainly by increasing BDNF levels, inhibiting proinflammatory cytokines and reducing cortisol secretion. Therefore, there is strong evidence of curcumin potential as a therapeutic agent in the neuropsychological and neurodegenerative context, especially when used in more bioavailable and highquality formulations [16,20,47,[77][78][79].…”

Curcumin is a polyphenol present in Curcuma longa, a root used in Asian cuisine for thousands of years, and it has several medicinal properties, acting as an antioxidant, anti-inflammatory, anticancer, among others. Polyphenols generally have the ability to restore BDNF (Brain Derived Neurotrophic Factor) levels, which is a very important neurotrophin in controlling neuronal development and survival, when they are impaired, offering a therapeutic effect. The aim of this study was to evaluate the effects of curcumin in Alzheimer's disease and Depression, which has as its main pathogenesis the reduction of BDNF levels, monoamine levels, increased oxidative stress, inflammation, beta-amyloid aggregation, Tau protein accumulation and aluminum neurotoxicity, verifying its therapeutic capacity. Therefore, a literature review was performed in the Scholar Google, ScienceDirect, and PubMed databases. The data analyzed demonstrated that curcumin supplementation is able to restore BDNF levels in Alzheimer's disease and depression, in addition to modulating monoamines and reducing oxidative stress, inflammation, beta-amyloid aggregation, Tau protein accumulation and aluminum neurotoxicity, improving their symptoms.
