Experimental groups were orally administered the water extract of Portulaca grandiflora at doses of 10, 100, and 1000 mg/kg per day. Recovery groups received 1000 mg/kg per day for 6 months followed by 14 days of husbandry without the extract. No significant changes in body weights, organ weights, or histopathological lesions were demonstrated in any of the groups. In female groups, no significant alteration in hematological or biochemical parameters was observed, while changes in male rats at 100 and 1000 mg/kg per day were not dose-related. The results suggested that the water extract of Portulaca grandiflora at the doses given did not induce any detrimental effects.

What side effects this plant can have?
This plant can cause serious physiological issues including bud proliferation, diminishing size of leaves, rosette formation, and stunted growth. When the plant experiences these health complications, the natural development of its structure becomes highly irregular. The abnormal bud proliferation often disrupts the standard flowering cycle of the species. Simultaneously, the diminishing size of leaves prevents the plant from performing efficient photosynthesis. These symptoms frequently culminate in tight rosette formation and overall stunted growth that prevents the organism from reaching maturity.
