Hawthorn Berry and Dandelion Root in Cardio Slim Tea
Hawthorn berry and dandelion root are named only in the Cardio Slim Tea sales copy, not on the brand graphic. Hawthorn's heart-failure research is conflicting (NCCIH - Hawthorn). Dandelion has no compelling evidence for any condition (NCCIH - Dandelion), and a 2.1 g root powder dose caused no extra urination in a 2026 test (Egan 2026 - Dandelion root diuretic test). Both matter most for people on heart drugs or water pills.

The basics
What are hawthorn and dandelion doing in Cardio Slim Tea?
They are the blend's two traditional "heart and water" herbs. Hawthorn has long been used for the heart, and dandelion root as a folk water pill.
Both appear in the sales page list of extra ingredients (Cardio Slim Tea sales page). Neither is on the "Inside Cardio Slim Tea" graphic. No amount is printed for either one.
The likely idea is support for the pouch claims "Advanced Cardiovascular Health Formula*" and "Supports Healthy Blood Pressure Levels*". The seller does not explain which herb is meant to do what.

Hawthorn berry
Does hawthorn help the heart?
The research is mixed. NCCIH, the federal center that studies herbs, calls the evidence for hawthorn in heart failure conflicting (NCCIH - Hawthorn).
One study of a hawthorn product may even have been linked to heart failure getting worse sooner. No studies have tested hawthorn use beyond 16 weeks. Those trials used hawthorn preparations made for the purpose, not a pinch inside a mixed tea.
Side effects reported include dizziness, nausea, vomiting, diarrhea and muscle pain. In January 2024, the FDA also warned that some "tejocote root" products, a related plant, contained toxic yellow oleander. That warning was about other products, not Cardio Slim Tea. It does show why plant identity and testing matter.
The sales page does not say which hawthorn species is used or whether batches are tested. For what the seller's codes mean, see testing and quality.
Dandelion root
Is dandelion root a natural water pill?
Not according to the best test we found. In a 2026 study, 14 active adults drank a liter of water with or without about 2.1 g of dandelion root powder (Egan 2026 - Dandelion root diuretic test). Urine output over four hours did not differ.
The only earlier human study was small. It gave 17 people a fresh leaf extract, not root, without supervision. They urinated a little more often on dandelion days, 9 times versus 8, but total urine over 24 hours did not change significantly.
NCCIH says very little is known about dandelion's effects on health, and there is no compelling evidence for any condition (NCCIH - Dandelion). Food amounts are likely safe.
The 2026 test used about 2.1 g of dandelion root alone. A pouch sold as a month is about 2 g of tea a day for all 14 ingredients together. Dandelion is only part of that.
Side by side
How do hawthorn and dandelion compare?
Neither has strong evidence for the pouch claims. Hawthorn has more heart research, but its results point in both directions.
| Question | Hawthorn berry | Dandelion root |
|---|---|---|
| Traditional use | Heart tonic | Water pill, digestion |
| Best human evidence | Heart-failure trials up to 16 weeks | One small 2026 test, one older leaf study |
| What it found | Conflicting; one study hinted at harm | No extra urine output from 2.1 g root powder |
| Blood pressure trials in our sources | None | None |
| Amount in Cardio Slim Tea | Not published | Not published |
| Main drug concern | Heart medicines, such as digoxin | Water pills, diabetes drugs, blood thinners |
Medicines
Can I take hawthorn and dandelion with heart medicine or water pills?
Ask your doctor or pharmacist first. These two herbs are the reason Cardio Slim Tea deserves a medicine check if you take heart drugs or diuretics.
NCCIH advises talking to a provider before using hawthorn if you take any medicine (NCCIH - Hawthorn). Dandelion might interact with water pills, diabetes drugs, blood thinners and antiplatelet drugs (NCCIH - Dandelion). Bring the full list of 14 ingredients to your appointment.

What symptoms should make me stop and call a doctor?
Stop the tea and call your doctor if you feel dizzy, faint, unusually weak, or notice a racing or very slow heartbeat. Those can signal a problem with heart medicine levels or blood pressure that dips too low.
- Dizziness when you stand up
- New stomach upset, nausea or diarrhea that does not settle
- Muscle pain or cramps, especially if you also take a water pill
- Rash, itching or swelling if you are sensitive to ragweed
Chest pain, pressure or shortness of breath is different. Call 911 right away. The side effects page covers the rest of the blend.
Fair view
Are hawthorn and dandelion worth having in the blend?
They add tradition more than proof. For most healthy adults, small tea amounts are unlikely to matter much. For people on heart drugs or water pills, they are the herbs to ask about.
Pros
- Long traditional use in heart and herbal teas
- Dandelion is a common food plant
- Likely small amounts in a 2 g daily cup
Cons
- Conflicting heart-failure results for hawthorn
- No water-pill effect in the 2026 dandelion test
- Named only in sales copy, with no amounts
- Possible interactions with heart drugs and diuretics

FAQ
Hawthorn and dandelion in Cardio Slim Tea: common questions
How much hawthorn is in Cardio Slim Tea?
The amount is not published. Hawthorn berry is named in the sales page ingredient list, but no gram figure appears for it or any other ingredient. With about 2 g of tea a day for all 14 ingredients, the hawthorn share is likely small and cannot be checked.
Is hawthorn safe with digoxin?
Ask your doctor before combining them. NCCIH advises talking with a provider before using hawthorn if you take any medicine, and heart drugs such as digoxin are the main concern. Do not change your digoxin dose on your own, and report any new dizziness or heartbeat changes.
Does dandelion root make you pee more?
A 2026 crossover study found it did not. Adults who took about 2.1 g of dandelion root powder with a liter of water passed the same amount of urine over four hours as with water alone. An older leaf extract study found only slightly more frequent trips.
Can I drink dandelion tea with a water pill?
Check with your doctor or pharmacist first. NCCIH says dandelion might interact with water pills, also called diuretics. Even if the effect is small, people on diuretics often have their salt and potassium levels watched, so any new herb is worth mentioning at your next visit.
Is dandelion root good for the liver?
There is no compelling evidence that it is. NCCIH says very little is known about dandelion's effects on human health and no condition has good support. Dandelion greens are a normal food. Claims that dandelion root cleanses the liver are not backed by the research we cite.
Is hawthorn good for high blood pressure?
No trial in our sources tests hawthorn for blood pressure. Its main research is in heart failure, where results conflict. If you have high blood pressure, proven steps like the DASH eating plan, less salt and prescribed medicine have much stronger evidence.
Can people with a ragweed allergy have dandelion?
They should be careful. NCCIH notes possible allergic reactions to dandelion in people sensitive to ragweed and related plants. Cardio Slim Tea also contains chamomile, from the same plant family. Talk to your doctor if you have had reactions to these plants before.
