Vasincu A et al. • Nutrients (2025)
“Even though additional research is required to fully assess their potential as therapeutic agents for NDs, by diving into the specific mechanisms through which they improve neurodegenerative processes, important steps can be made towards this endpoint.”
Key Findings:
- This review synthesizes experimental evidence regarding Ocimum species with neuroprotective potential in AD, particularly Ocimum sanctum and Ocimum basilicum.
- These plants are rich in bioactive compounds including polyphenols, flavonoids, essential oils, and triterpenoids that synergistically scavenge reactive oxygen/nitrogen species, upregulate endogenous antioxidant enzymes (SOD, CAT, and GPx), and reduce lipid peroxidation.
- Furthermore, these extracts have demonstrated the ability to decrease β-amyloid accumulation and tau protein levels, key pathological features of AD.
- Even though additional research is required to fully assess their potential as therapeutic agents for NDs, by diving into the specific mechanisms through which they improve neurodegenerative processes, important steps can be made towards this endpoint.
Lopresti AL et al. • Nutritional neuroscience (2022)
“For most phytonutrients, the effects of supplementation on HPA-axis activity in humans is unclear.”
Key Findings:
- For most phytonutrients, the effects of supplementation on HPA-axis activity in humans is unclear.
- Before more definitive conclusions about the effects of phytonutrients on the HPA-axis can be made, further research is required.
- Further research warranted to confirm findings

“These plants hold the potential to serve as novel therapeutic agents in the treatment of respiratory diseases.Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.”
Key Findings:
- Some medicinal plants, notably Echinacea purpurea and Zingiber officinale, exhibit potential for adjuvant symptomatic therapy in respiratory conditions, such as chronic obstructive pulmonary disease (COPD), bronchitis, asthma, the common cold, cough, and whooping cough.
- The leaves of medicinal plants like Acacia torta, Ocimum sanctum, Mentha haplocalyx, Lactuca virosa, Convolvulus pluricaulis, and Acalypha indica are commonly used to address pneumonia, bronchitis, asthma, colds, and cough.
- This review aims to shed light on specific medicinal plants with therapeutic value, providing valuable insights for researchers in the field of herbal medicine.

K V et al. • Preparative biochemistry & biotechnology (2025)
“This review merges traditional and modern approaches to UA extraction, bioavailability enhancement, and sustainable use, offering new perspectives on its potential in medicine, food technology, and cosmetics.”
Key Findings:
- EAE boosts efficiency by breaking down cell membranes, allowing sustained UA release.
- With antibacterial, anticancer, antidiabetic, and anti-inflammatory effects, UA holds promise in therapeutics and has applications in nutraceuticals, cosmetics, and food preservation.
- However, its low water solubility and bioavailability require innovative delivery methods like dendrimers and nanoparticles.
- This review merges traditional and modern approaches to UA extraction, bioavailability enhancement, and sustainable use, offering new perspectives on its potential in medicine, food technology, and cosmetics.
Kumari S et al. • Recent advances in food, nutrition & agriculture (2024)
“Thus, the diverse properties of Ocimum sanctum offer exciting opportunities for the development of functional foods that can promote specific health issues, so future research should focus on developing and analyzing novel Ocimum sanctum-based functional foods to meet the growing demand of the functional food industry.Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.”
Key Findings:
- This study highlights historical, botanical, ecological, and phytochemical descriptions and different extraction mechanisms of Ocimum sanctum utilized in its processing.
- In terms of other pharmacological properties, Ocimum sanctum-infused functional foods exhibited cognitiveenhancing properties, adaptogenic qualities, anti-obesity effects, gastroprotective, antiinflammatory, hypoglycemic, and immuno-modulatory effects.
- Further research warranted to confirm findings
