The effect of Saururus chinensis Baill against oxidative damage and inflammation
TLDR
The data indicate that S.chinensis Baill, a perennial herb commonly called Chinese lizard’s tail or Sam-baek-cho in Korea, shows anti-oxidant activity and anti-inflammatory effect.
Analysis of free-radical scavenging of Yerba Mate (Ilex paraguriensis) using electron spin resonance and radical-induced DNA damage.
TLDR
It is indicated that Yerba Mate possesses potent antioxidant effects against hydroxyl and superoxide radicals in both chemical and cell culture systems, as well as DNA-protective properties.
Buddleja officinalis prevents the normal cells fromoxidative damage via antioxidant activity
TLDR
The results suggest that Buddleja officinalis may exert the inhibitory effect on ROS-induced carcinogenesis by blocking oxidative DNA damage and cell death by blocking hydroxyl radical via antioxidant activities.
Antioxidative and in vitro antiproliferative activity of Arctium lappa root extracts
TLDR
The hydroethanolic extracts exhibited the strongest free radical scavenging activity, while the highest phenolic content was observed in Soxhlet extraction, and the dichloromethane extracts showed selective antiproliferative activity against human cancer cell lines.
Schisandra Chinensis Inhibits Oxidative DNA Damage and Lipid Peroxidation Via Antioxidant Activity
TLDR
It was found that Schisandra chinensis possesses a spectrum of antioxidant and DNA-protective properties and it inhibited oxidative DNA damage, lipid peroxidation and cell death induced by hydroxyl radical.
In vitro analysis of the herbal compound Essiac.
TLDR
In vitro analysis of Essiac indicates significant antioxidant and immunomodulatory properties, as well as neoplastic cell specific cytotoxicity consistent with the historical properties ascribed to this compound.
Gastroprotective activity of the chloroform extract of the roots from Arctium lappa L.
TLDR
The results show that the CE protects animals from gastric lesions by reducing gastric acid secretion via inhibition of gastric H+, K+‐ATPase.
Total phenolic content, antiradical and antioxidant activities of wild and cultivated Rumex acetosella L. extracts
Edible greens, especially wild greens, play an important role in traditional diets and are rich in phenols and other compounds. The purpose of this study was to investigate total phenolic content
Antimicrobial activity of the extracts from fruits of Rumex L . species 1
TLDR
The objective of the present study was to screen in vitro the antimicrobial activity of the extracts obtained from fruits of R. acetosa, R. confertus, and R. crispus of Rumex genus growing in Poland.

Peroxynitrite scavenging activity of herb extracts
TLDR
It was found that witch hazel (Hamamelis virginiana L.) bark showed the strongest effect for scavenging ONOO− of the 28 herbs, and it is suggested that hamamelitannin might be developed as an effective peroxynitrite scavenger for the prevention of ONOO − involved diseases.
Antioxidant properties of fruit and vegetable juices: more to the story than ascorbic acid.
TLDR
The present study showed that the free radical scavenging capability of each individual juice, but not its ascorbic acid content, is correlated with its protective effect on free radical induced lipid peroxidation, indicating that consumption of whole fruits and vegetables would be superior to an ascorBic acid supplement for antioxidant effectiveness.
Tea and tea polyphenols in cancer prevention.
TLDR
The results from animal studies and possible cancer inhibitory mechanisms that might be applicable to human cancer prevention are discussed and the levels of tea polyphenols in blood, urine and tissue samples have been analyzed, and the pharmacokinetic properties of teapolyphenols studied.
Generation of reactive oxygen species in the enzymatic reduction of PbCrO4 and related DNA damage.
TLDR
It is reported that reduction of insoluble PbCrO4 by glutathione reductase in the presence of NADPH as a cofactor generated hydroxyl radicals (’OH) and caused DNA damage.
Polyphenolic flavanols as scavengers of aqueous phase radicals and as chain-breaking antioxidants.
TLDR
Against propagating lipid peroxyl radical species, epicatechin and catechin are as effective as ECG and EGCG, the least efficacious being EGC and GA.
In vitro comparison of Essiac and Flor-Essence on human tumor cell lines.
TLDR
Flow cytometry analysis showed that both ES and FE treatment between 1/10 and 1/100 dilutions only slightly affected the cell cycle progression of MCF7, MDA-MB-468, Jurkat and HL60 cells.
Metal-induced oxidative damage in cultured hepatocytes and hepatic lysosomal fraction: beneficial effect of a curcumin/absinthium compound.
TLDR
These data support the potential clinical application of curcumin-containing compounds in metal-induced liver injury and show PN-M001 was significantly better than sylibin in suppressing acid phosphatase enzyme activity.
The chemistry and biological activity of herbs used in Flor‐Essence™ herbal tonic and Essiac
TLDR
Experimental studies with individual herbs have shown evidence of biological activity including antioxidant, antioestrogenic, immunostimulant, antitumour, and antiocholeretic actions, but research that demonstrates these positive effects in the experimental setting has not been translated to the clinical arena.
