What will this herb do for me?
Bilberry is used to relieve the symptoms of mild diarrhoea and improve poor night vision, sensitivity to glare, photophobia, peptic ulcers, varicose veins, venous insufficiency and haemorrhoids when taken internally. It is also used as a mouthwash, gargle or paint for mild inflammation of the mouth or throat, such as gingivitis or pharyngitis.
When will it start to work?
This depends on the indication. Improvements in night vision, photophobia and glare sensitivity have been reported within 2-4 weeks of use in some people whereas preventive effects are likely to require long-term use. In peripheral vascular diseases, 30 days' treatment may be required before effects are noticed. Are there any safety issues?
Considered a safe herb overall, bilberry can theoretically reduce blood glucose levels in people with diabetes and so should be used carefully in these patients. At very high doses it may interact with warfarin and antiplatelet drugs.
