abstract
Digestive system disorders have a substantial effect on worldwide morbidity and mortality rates. The other remedy is to solve digestive disorder drug chemical drugs that are; Mixmag, Boscopand, Doxycycline, flangy, Hyoscine, Vitamin C, some of which have their side effect. Medicinal plants including Vernonia amygdalina, Terminalia chebula, Ocimum gratissimum, Cinnamomum zeylanicum are the main herbal agents traditionally used by most Nigeria people to treat digestive disorder particularly, in the rural areas. To value the traditional use of these plants, Ethno-medicinal survey of herbal plants used for digestive disorder was conducted in Ibarapa Area of Oyo state, Nigeria. Primary data was collected from 30 concoction and herbal sellers who were randomly selected through a cluster sampling procedure. The result revealed a modern age of 20-29 years sell the herbs and concoction of wh66.7% of which were females while 33.2% were males. According to the herbal sellers, Ocimum gratissimum, Vernonia amgdalina and Cinnamomum zeylanicum were the most used herbs for the treatment of digestive disorder. Phytochemical screening of the plants indicated that, plants metabolites like Alkaloids, flavonoids, tannin, steroids, terpenoids, saponin, phenol and coumarin were present. However, quantitative study of the plants revealed that Ocimum gratissimum had the highest concentration of flavonoids (12.33mg/g), followed by Vernonia amygdalina (6.222mg/g) while the least was Cinnamomum zeylanicum (3.213mg/g). All the three plants were relatively high in tannin and total phenolic constituents. Therefore, presence of these phyto-chemical components could permit to justify their usage against digestive disorder.
