The leaves are often prepared as infusions or poultices to address skin irritations and inflammatory conditions. When processed, the stem can be used in traditional remedies to alleviate digestive discomfort. These specific plant parts contain bioactive compounds that contribute to their therapeutic properties. Local practitioners rely on these components to manage a range of minor health concerns.
According to a study published by "The British journal of nutrition", the voluntary intake of the leaf fraction of Panicum maximum was 8.23 kg/d compared to 3.67 kg/d for the stem fraction (P less than 0.001). The total number of eating chews per day was 1.6 x 10(4) for the leaf versus 9.8 x 10(3) for the stem (P less than 0.05). For the leaf fraction, the mean resistance of large particles to breakdown during eating was 8.4, while the stem fraction was 23.7. The mean resistance of large particles to breakdown by ruminations was 8.2 for the leaf and 13.2 for the stem (P less than 0.01).
