Field of application/useThis section has been translated automatically.
Gentinae radix is found as a stomachic, i.e. appetite and digestion stimulant, amarum, i.e. bitter agent to stimulate saliva and gastric juice, as well as tonic, i.e. overall invigorating agent.
Gentian root has a tonic and digestive effect. Traditionally, gentian root is used for loss of appetite, stomach complaints, but also colds and other inflammations. Due to the stimulation of gastric juices and intestinal activity, gentian root has a slight laxative effect, see also contraindication. Its use in liver and gall bladder disorders has also been described.
DosageThis section has been translated automatically.
Unless otherwise prescribed, it should be taken 2 to 4 times a day to stimulate the appetite about 30 minutes before meals. In the case of digestive problems, it is taken after each meal. Here, one cup of the tea infusion is taken as follows: pour boiling water (approx. 150 ml) over approx. 1 g of the gentian root and after approx. 10 to 15 minutes strain it through a tea strainer if necessary.
