The effects of Plumbago scandens extracts were investigated on tremors in mice induced by tremorine, a model of Parkinson's disease. At low doses, the extracts did not have an effect, but at high doses of 1000-2000 mg/kg, they were effective in reducing tremors for up to an hour. Biperiden, an anticholinergic drug, was used as a control and also was effective. This suggests that Plumbago scandens may have potential therapeutic use in treating Parkinson's disease.
The study found that S. xanthocarpum and S. trilobatum herbs improved lung function and reduced symptoms in bronchial asthma, comparable to deriphylline but less effective than salbutamol. No side effects were observed.
