Common Names: bush mint, spearmint
Researchers tested a combination of B. integerrima root extract and spearmint essential oil for treating acne vulgaris. Both ingredients have antimicrobial, antioxidant, and anti-inflammatory properties. This study evaluates their clinical effectiveness.
Essential oils from various plants in the Lamiaceae sub-family Nepetoideae have been shown to have cognitive and mood effects possibly related to their effects on neurotransmitters. Researchers conducted a double-blind, placebo-controlled study to assess the cognitive and mood effects of peppermint essential oil, which showed promising in vitro properties. The study involved 24 participants who consumed single doses of encapsulated placebo and peppermint essential oil. The highest dose of essential oil improved performance on the demanding Rapid Visual Information Processing task and attenuated fatigue, compared to the placebo. Peppermint oil also showed cholinergic inhibitory, calcium regulatory, and GABA/nicotinic receptor binding properties. Future studies should examine higher doses of peppermint essential oil.
Nanoparticles, specifically Fe nanoparticles made from Mentha spicata extract, show great potential for targeted colon cancer treatment with reduced side effects. Further clinical trials needed.
Silver nanoparticles in gel improves wound healing in diabetic rats. Bioactive compounds from high altitude plants may have potential for wound healing. Useful for lab research.
This study found that raw vegetables and herbs in Bangkok have a high prevalence of Escherichia coli and are resistant to multiple antibiotics, which may contribute to foodborne illnesses.
Researchers evaluated the antioxidant capacity of spearmint essential oil and dew. 1% spearmint oil had the strongest antioxidant effect (50.94% superoxide scavenging, 90.11% hydroxyl scavenging), while 100% dew had moderate effects (47.65% superoxide scavenging, 45.60% hydroxyl scavenging). This is relevant for developing spearmint truffle and oil.
This study found that harvesting spearmint at 9 a.m. and distilling it for 60 minutes resulted in the highest menthol content and antioxidant activity. It suggests that sun exposure and longer distillation times decrease menthol content and alter the chemical composition.
Researchers prepared glycerosomes of an essential oil (EO) to improve its stability and solubility. The optimized EO-loaded glycerosomes showed sustained release and enhanced antibacterial effects, making them a potential solution for food and clinical industries.
Study finds 40.2% of participants in a Brazilian city use medicinal plants, primarily for anxiety. Females, non-whites, and lower-educated with higher income and comorbidities were more likely to use. No reported use for treating COVID-19.
This study fabricated silver nanoparticles using Mentha spicata and found they have significant antibacterial and antioxidant properties. They are stable at various pH and temperatures.
This study evaluated the anti-inflammatory and anticancer effects of pharma-grade essential oils, specifically spearmint and German chamomile. The oils were tested using enzyme assays and evaluated for their cytotoxic effects on various cell lines. The major components of the oils were identified, and their IC values were calculated. The essential oils were found to have no cytotoxic effects on healthy cells but increased apoptotic activity in cancer cells. Additionally, the oils showed selective inhibition of the COX-2 enzyme. These findings suggest a potential dual mode of action for the essential oils and warrant further investigation.
