Black rowan is a tonic and antihypertensive herbal remedy. Depending on the manufacturer, the drug can be both a dietary supplement and a medicine (for hypertension).
The plants that make up rowan have a P-vitamin effect: they normalize the content of potassium ions in the blood, help normalize blood pressure in tissues and increase blood circulation.
The fruits of chokeberry and chokeberry are used as a raw material source for the production of this medicine. Fruit harvesting is carried out during the period of full ripening. After harvesting, the fruits are dried in the sun for 7-15 days or at a temperature of 40-50 degrees Celsius. Both fresh and dry rowan berries are suitable for use for medicinal purposes.
