Extracts (Greater Galangal) :
The alcoholic extract of the rhizome lowered temperature in mice and potentiated amphetamine toxicity (MPI). EO of the rhizome inhibited Mycobacterium tuberculosis at 25 mg/ml. It was more potent against gram-negative bacteria (at 0.4 - 0.6 mg/ml). LD50 of the oil in guinea pigs was 0.68 ml/kg (mode of administration not stated) (MPI). 1-acetoxychavicol-acetate and 1-acetoxyeugenol-acetate are powerful antiulcer agents (WO2). Steam volatile portion of rhizome extracts stimulated the bronchial glands; the nonvolatile portion acted reflexly through the gastric mucosa.
