Redflower ragleaf is often found in fertile wastelands, river banks, roadsides, tea and quinine plantations, especially in damp areas. Also in the dry fields. This plant is identified as a bi-season weed that is easily overcome.

Sintrong is thought to contain pyrolizidine alkaloids which can trigger tumors, but traditional societies utilize them as vegetables and animal feed. Some parts of the plant are used to treat stomach disorders, headaches, wounds, hemostasis, tonic, laxatives, fever, tonsillitis and eczema.
