Influence of Comminution Methods and Air Exposure in the Production of Melissa officinalis Mother Tincture.
Article in Complementary medicine research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionDuring the processing of fresh plants, prolonged exposure to the air can cause rapid oxidative changes, and this is further accelerated if they have large surface areas. These changes can ultimately lead to losses in valuable ingredients and deterioration of the final product. Consequently, in the food, cosmetics, and pharmaceutical industries, oxidation and the use of antioxidant conservatives are major considerations during processing and production. However, similar considerations are not currently made for herbal medicines. The differences in the UV-Vis spectra of several commercial herbal mother tinctures were investigated here to determine if the oxidation process occurred and should thus be considered during their production.
methodsThe impact of air exposure on comminuted fresh Melissa officinalis and on the quality of the resulting mother tincture was evaluated using UV-Vis spectrophotometric analysis, antioxidant tests (potassium permanganate and FOLIN-Ciocalteu), and high-performance thin-layer chromatography.
resultsA time-dependent decrease in phenolic compounds, UV absorbance, and antioxidant capacity of the Melissa officinalis mother tincture were observed. Specifically, the antioxidant capacity of ground Melissa officinalis in the resulting herbal mother tincture was reduced by 40.47% and 55.52% after 5 and 30 min of air exposure, respectively.
conclusionsThe results indicate that the Melissa officinalis mother tincture is affected if its comminuted starting material is exposed to air during the manufacturing process and that this should be considered when producing fresh herbal medicine plant products in the future.
