Effects of Ya-hom on blood pressure in rats

Evaluation of the Antioxidant Activities of Ya-hom Intajak, a Thai Herbal Formulation, and its Component Plants

“…The effect of Ya-hom on the pulse rate and pulse pressure in human has been reported [7]. The effect of the herbal preparation on blood pressure in rats and in isolated rat aortic ring and atrium have also been investigated [8][9][10]. However, the results obtained by the different studies were not in agreement and remain inconclusive, most probably due to the use of different Ya-hom formula, extraction methods and experimental models.…”

Efficacy and safety of “Yahom” as a traditional Thai herbal therapy: A systematic review

“…Nine additional articles were identified through manual searches of the references, bibliographies and consultations with experts. This yielded 24 articles which met the inclusion criteria including 2 in vitro cell lines or bacteria (Sripanidkulchai et al, 2007;Tepsuwan et al, 2011), 3 in vitro cell-free (Channarong et al, 2012;Nalinratana et al, 2014;Tuekaew et al, 2014), 5 in vitro animal tissue studies (Chantharangsikul et al, 2009;Nonthasawadsri et al, 2015;Nusuetrong et al, 2012;Pataloong and Sawasdimongkol, 1995;Suvitayavat et al, 2005b), 13 in vivo animal studies (Chavalittumrong et al, 2009;Intayoong, 2006;Jariyapongskul et al, 2006;Kengkoom and Ampawong, 2015;Kengkoom et al, 2012;Matangkasombat, 1974;Nernpermpisooth et al, 2015;Sirisangtragul and Sripanidkulchai, 2013;Sirisangtrakul and Sripanidkulchai, 2011;Suvitayavat et al, 2004;Suvitayavat et al, 2005a;Thongpraditchote et al, 1999) and 1 human study (Suvitayavat et al, 2005) (Fig 1).…”

“…Thus, a better understanding of their efficacy, interactions and adverse actions is needed to promote and protect public health and safety. Thus far, most scientific data about Yahom is derived from animal and in vitro studies (Jariyapongskul et al, 2006;Suvitayavat et al, 2004;Suvitayavat et al, 2005a). To date, no systematic review which integrates and assesses the reliability of this evidence on Yahom has been undertaken.…”
