Flush Factor Plus contains uva ursi, juniper berry, buchu, cornsilk, parsley, watermelon seed, apple cider vinegar, vitamin B6, potassium and magnesium. Its main herb, uva ursi (bearberry), is approved in Europe only for short-term use in adult women, for no longer than a week.[1] We found no trial of the product, and diuretic-style herbs do not treat the cause of swelling.[3]

Before you read: swelling can be serious
Get medical help first if…
- Call 999 (or your local emergency number) if swelling comes with chest pain or tightness, breathlessness, coughing up blood, or feeling faint. These can be signs of a blood clot in the lungs.[3]
- Get an urgent GP appointment or call 111 if swelling is in one leg only with no clear cause, is sudden, painful or getting worse, the skin is red or hot, or you have a high temperature.[3]
- See a GP if swelling in both legs has not improved after a few days, or you have a heart, kidney or vein condition.[3]

Does Flush Factor Plus work?
Herbs like these can make you pass more urine for a while, which may make you feel less bloated. That does not treat common causes of swelling such as sitting for long periods, salty food, medicines or vein problems.[3] Lymphoedema is not treated with diuretics.[7]
Who should avoid it
- Pregnant or breastfeeding women.[1]
- People with kidney disease or heart failure, or taking water tablets, lithium or blood pressure medicines.[5]
- Anyone planning to use it for more than a week (uva ursi).[1]

Pros and cons
Strengths
- Lower price than many products
- Simple, familiar herbs
Drawbacks
- Diuretic-style, not lymph-focused
- Uva ursi only suitable short-term
- No product trials
Our verdict
Flush Factor Plus is best understood as a short-term herbal "water pill". It may suit occasional bloating in healthy adults for a few days. It is not a long-term or lymph treatment, and anyone with ongoing swelling should see a doctor.
Common questions
Is Flush Factor Plus a diuretic?
Its main herbs are traditional diuretics, so it works in a similar way. Uva ursi should not be used for more than a week.[1]
