Anti-oxidant and anti-inflammatory activities of the various kinds of herbal tea

Abstract

Objectives : Reactive oxygen species (ROS) are involved in a wide spectrum of diseases including chronic inflammation and cancer. In this study, we investigated the antioxidant activities and anti-inflammatory effects of the extracts from the herbal teas such as Lonicera japonica Thunberg (L. japonica), Chrysanthemum morifolium Ramat (C. morifolium), Mentha arvensis L. (M. arvensis), and P.rhizoma. Methods : Anti-oxidant activity was evaluated using DPPH radical scavenging assay and Fe 2+ chelating assay. And DNA cleavage assay was performed to evaluate an anti-oxidative effect. Anti-inflammatory effect was performed using NO generation assay and western blot in LPS-stimulated RAW264.7 cell line.

The efficacy, effectiveness, and safety of Kyung-ok-ko: A narrative review

“…KOK contains amino acids (valine, aspartic acid, and arginine) and 14 minerals (K and Na). [4] Particularly, the extract using chloroform as a solvent displayed highest antioxidative activity. [4] Moreover, while examining each of the studies on the individual herbs that constitute KOK, the primary herb Rehmannia glutinosa var.…”

“…[4] Particularly, the extract using chloroform as a solvent displayed highest antioxidative activity. [4] Moreover, while examining each of the studies on the individual herbs that constitute KOK, the primary herb Rehmannia glutinosa var. Purpurea displays efficacy in various inflammatory and metabolic diseases owing to its anti-inflammatory, antioxidant, hypoglycemic, and autonomic nervous system activities.…”

“…According to a general analysis of medical books, KOK improves health by filling Jing (精) and bone marrow, treats dizziness and forgetfulness owing to the lack of brain water, and can be used for a prolonged time in gastrointestinal and respiratory diseases. [2,3] Recent reports have demonstrated the biochemical analysis of KOK and individual herbs consisting of KOK, [4][5][6][7][8][9][10] and several experimental and clinical studies related to KOK have been regularly published. In addition, researchers are developing numerous products that use KOK for non-therapeutic purposes, such as food (vinegar, [11] beverages, [12] and yogurt [13] ) and cosmetics [14] ; moreover, studies have demonstrated the effectiveness of these products.…”

Physicochemical properties and physiological activity of bean sprouts extract containing Hovenia dulcis Thunb concentrates

“…Natural antioxidants containing vitamins, carotenoids, phenols, and other such compounds serve as bioactive materials in preventing oxidative stress, which causes adverse conditions, including allergies, inflammation, and arteriosclerosis (Van, 2016). Additionally, polyphenolic compounds exhibit that may readily bind to proteins and various other compounds as aromatic compounds, and thus, display outstanding anticancer and -oxidant and anti-inflammatory effects (Kang et al, 2002a;Lee et al, 2008). This may be the cause of the excellent antioxidant efficacy of BHM in this study, as it is enriched with polyphenols and flavonoids.…”
