    1. Kerala farmers medicine for rhinitis/sinusitis, extraordinarily effective: carefully heat Mimosa pudica leaves in a light vegetable oil for 5 to 10 minutes, cool down, rinse. Apply directly into nose once daily, later once weekly, later once monthly. Cures rapidly acute and even persistent chronicle infections – a wonder in herbal medicine.
    2. Venezuela farmers medicine for pile: slice or crush portion of rhizome of common Heliconia spp. (e.g. Heliconia rodriguensis) and heat/fry in light vegetable oil. Apply oil to pile. I tell you: just another wonder in herbal medicine.
