Herbal remedies for high blood pressure

[Hypertension](/conditions/hypertension/) may have no noticeable symptoms while gradually straining blood vessels and organs. Herbal products can contain several active ingredients, vary between brands, and affect fluid balance, heart rate, or the way medicines are broken down. Licorice-containing products are one example that can raise blood pressure or disturb body salts. People with [Chronic Kidney Disease](/conditions/chronic-kidney-disease/), heart problems, or pregnancy need individual advice before using supplements.

Keep taking prescribed treatment as directed and do not use a supplement to compensate for missed doses. Record home readings using the technique your clinician recommended, and bring the product container or a photograph of its ingredients to a pharmacist. Limit products marketed for rapid detox, energy, or weight loss because their contents may be unclear. Regular activity, less salty processed food, good sleep, and support with weight management can complement—not replace—your treatment plan. Review medicines and supplements at a GP appointment.

Seek emergency help for severe chest pain, sudden weakness or numbness, trouble speaking, new confusion, severe breathlessness, or sudden vision loss. These can signal problems such as [Stroke](/conditions/stroke/) or another urgent condition. Arrange prompt review if readings remain high, medicines cause troubling effects, or you have stopped treatment. Do not wait for a supplement to change an urgent reading.

Ask whether a specific ingredient affects your medicines, how to monitor readings, what target applies to you, and which symptoms should trigger emergency care.
