The continuous use of medicinal plants as a source of bioactive compounds can pose a threat of scarcity of medicinal plants. Another way to obtain bioactive compounds is to use endophytic bacteria. The use of endophytic bacteria is more efficient because the growth time is faster than medicinal plants. The endophytic bacterial isolate D.SB 1.1 isolated from sea fern (Acrostichum aureum L.) cont…
The high demands of daily life require the body to be in optimal condition. However, excessive physical exertion can lead to fatigue. To alleviate fatigue and quickly restore energy, tonic substances, including stamina-boosting tonics, can offer a solution. In addition to synthetic substances, tonics can also be derived from natural sources, such as the water and oil of the kapur tree (Dryobala…
