Who should check with a doctor or pharmacist before using this product?

This balm contains heparin sodium, horse chestnut extract (a source of escin), leech extract, and essential oils (cypress, juniper, lemon) — ingredients that act locally on the skin and vessel area. While it is a cosmetic and not a medicine, certain situations warrant professional advice before use:

• Pregnancy and breastfeeding: safety of topical heparin and the combined botanical extracts has not been established for these periods; a pharmacist or doctor can assess your individual case.
• Anticoagulant or blood-thinning medication: heparin sodium is related to systemic anticoagulants; although topical absorption is low, a specialist should confirm there is no interaction risk.
• Known sensitivity to any ingredient: especially to horse chestnut, leech extract, menthol, or the listed essential oils.
• Persistent or worsening vein-related symptoms: such as swelling, pain, skin discoloration, or ulcers — these require medical evaluation and the balm is not a substitute for treatment.

If none of the above apply, the product is generally well tolerated for cosmetic leg care. Discontinue use if irritation occurs.
