Dr. Reckeweg R42 Haemovenin Varicosis Drops are intended for conditions related to varicose veins and circulation problems, not for eczema. Since your concern is eczema patches on the knee and leg, this remedy is not appropriate for treating those symptoms. For your condition, it is best to consult a doctor or dermatologist who can properly evaluate your skin, identify the underlying cause, and prescribe appropriate medication or topical treatment. Please avoid using remedies meant for other conditions, as this may delay effective care.
