Formulation of Herbal Oil using The Leaves of Psidium guajava and its Characterization

A herbal oil made from the leaves of Psidium guajava L. (guava) was made and put through a variety of tests, including sensitivity, irritation, grittiness, specific gravity, pH, acid value, saponification value, ester value, and physical characteristics including colour, density, and odour. The oil's chemical composition was further examined using Fourier Transform Infrared Spectroscopy (FTIR) and gas chromatography and mass spectrometry (GCMS). The oil's smooth texture was revealed by grittiness, and the sensitivity test showed no signs of irritation, redness, or noticeable skin changes. FTIR revealed the oil's chemical composition, whereas GCMS revealed the bioactive substances that may provide the oil antibacterial, antioxidant, and anti-dandruff properties. After completing its biological action, Psidium guajava leaf oil may be used as a herbal hair oil to treat bacterial infections and dandruff.
