Studies
• Anti-Ulcer: A study on the aqueous and methanolic leaf extracts of P barbatum showed reduction of gastric volume, total acidity, free acidity and ulcer index. The antiulcer activity may be due to the presence of flavanoids and tannins.
Wound-Healing: A study of wound healing on albino rats of Wistar strain showed a significant increase in wound closure rate, tensile strength and decrease in epithelization perioe in PB treated group. Study concludes that ethanolic extract of P B had greater wound healing activity than nitrofurazone ointment.

Cultivation:

There is a difference amongst botanists as to how this species should best be treated. In the Flora of China it is treated as one aggregate species, but in the Flora of Japan it is split into two distinct species and moved to a different genus as Breea segetum and Breea setosum. The plant has wide-ranging roots that send up adventitious shoots and so it has the potential to become an invasive plant in areas to which it is introduced. This species is dioecious, male and female plants must be grown if seed is required. The following notes are based on the general needs of the genus. An easily grown plant, succeeding in any ordinary garden soil in a sunny position.
