“…In addition, this herb has been traditionally used as a health enhancer, as a wound healer (Suntar et al, 2010), as well as for antibacterial (Schulz, 1995;Saddiqe et al, 2010) anti-viral (Hudson et al, 1991;Pang et al, 2010) and anti-retroviral (Lavie et al, 1989;Chinsembu & Hedimbi, 2010) activities; finally, a strong antitumor effect has been recently reported (Schempp et al, 2002;Beerhues, 2006;Medina et al, 2006). Phytochemical characterization reports hyperforin (a prenylated phloroglucinol) and hypericin (a naphthodianthrone), as the main chemicals responsible for effects on health, although other biologically active constituents, e.g., flavonoids, tannins, are also present (Barnes et al, 2001).…”
