“…Herbal medicine powder, its products and extracts have been characterized by analytical methods. Scanning electron microscopy (SEM) is used to characterize the morphology and particle size of herbal medicine powder [12,13]; thermal analysis such as thermogravimetry (TG) and differential thermal analysis (DTA) together with pyrolysis coupled to gas chromatography/mass spectrometry is employed to evaluate the quality of pharmaceuticals [14][15][16], as well as atomized extracts of herbal medicine like E. mulungu [17] and distinct brands and batches of Cymbopogon citratus teas [18]. Figure 1 shows the micrographs from samples CAR 01, 02 and 03.…”
