Ginger and Lemongrass in Cardio Slim Tea: Warmth, Citrus and a Dose Gap
Ginger root is on the Cardio Slim Tea brand graphic, and lemongrass is named in the sales copy. In 6 trials, ginger lowered systolic pressure by about 6 points, but only at 3 g a day or more (Hadi 2019 - Ginger BP meta-analysis). A whole day of the tea is about 2 g for all 14 ingredients. Lemongrass is mainly flavor, with no trials in our sources.

The basics
Why are ginger and lemongrass in the blend?
Mostly for taste and warmth, with one research angle for ginger. Ginger root gives a gentle bite. Lemongrass adds a bright, lemony note without any lemon.
The two are named in different places. Ginger root is one of the six ingredients on the brand graphic. Lemongrass appears only in the longer list on the sales page, among eight more names. Neither has a published amount.
| Name on the sales page | Ginger Root |
|---|---|
| What it is | Zingiber officinale rhizome |
| Where it is named | On the brand graphic |
| Amount in the tea | Not printed |
| Amount used in research | 3 g a day or more in the trials that showed a BP effect |
| Strength of evidence | Mixed; effect only at 3 g a day or more |
| Marketed use | Warming spice for digestion |
| Main caution | Heartburn and stomach upset are the usual side effects. |
| Name on the sales page | Lemon Grass |
|---|---|
| What it is | Cymbopogon citratus leaf |
| Where it is named | Named in the sales copy |
| Amount in the tea | Not printed |
| Amount used in research | No human BP or weight trial in our sources |
| Strength of evidence | Untested for these claims |
| Marketed use | Citrus flavor |
| Main caution | Mainly a flavor; no safety issue found in our sources at tea amounts. |
Ginger research
Does ginger help blood pressure?
Possibly, at larger doses. A review of 6 randomized trials with 345 people found systolic pressure about 6.4 points lower and diastolic about 2.1 lower (Hadi 2019 - Ginger BP meta-analysis).
| Detail | Finding |
|---|---|
| Average change | About 6.4 lower systolic, 2.1 lower diastolic |
| Daily amount where it showed | 3 g of ginger a day or more |
| Trial length where it showed | 8 weeks or less |
| Age group where it showed | People 50 or younger |
| Agreement between trials | Low: heterogeneity about 90% for systolic |
So the average hides a narrow pattern. The clear effect appeared only in some groups, and the trials disagreed a lot. The authors said more studies are needed (Hadi 2019 - Ginger BP meta-analysis).
Many people who worry about blood pressure are over 50. The trials did not show a clear effect in that group.
The dose gap
Is there enough ginger in Cardio Slim Tea to matter?
Probably not, based on our math. The trials that showed an effect used 3 g of ginger alone each day (Hadi 2019 - Ginger BP meta-analysis).
A 60 g pouch sold as about a month works out to about 2 g of tea a day. That whole amount is shared by 14 named ingredients. Even if the blend were half ginger, which nobody claims, it would hold about 1 g a day.
3 g of ginger alone in trials, versus about 2 g of tea in total, split 14 ways in Cardio Slim Tea. The real split is not published.
Ginger can still add a pleasant warmth to the cup. That is a fair reason to enjoy it. It is not a reason to expect a blood pressure change. For what the pouch itself prints, see the pouch label page.
Side effects
What side effects can ginger cause?
Mostly stomach-related ones. The NCCIH lists abdominal discomfort, heartburn, diarrhea and mouth or throat irritation (NCCIH - Ginger).
- Heartburn is the effect people notice most in strong ginger drinks
- Taking tea with food may feel easier on the stomach
- The NCCIH ginger fact sheet does not cover blood pressure at all
Ginger has better support for nausea in pregnancy than for heart health (NCCIH - Ginger). Even so, anyone pregnant or nursing should ask a doctor before using a multi-herb tea like this one.
Lemongrass
What does lemongrass do in Cardio Slim Tea?
Mainly it adds flavor. Lemongrass is a tall grass with a citrus scent, common in Thai and Vietnamese cooking and in herbal teas.
We found no human trial of lemongrass for blood pressure or weight in the sources we use. Research for these claims is lacking. That does not mean it is harmful; it means the evidence is missing.
At tea amounts, our sources show no safety issue for lemongrass. Its main role is to make a blend of roots and leaves taste brighter.

How can you try the tea without guessing?
Start with the pouch, then your medicines, then a simple log. Four steps keep the trial honest.
- 01
Read your pouch
Brewing directions are printed on the pouch. No image we were given shows them, so follow the pouch, not this site.
- 02
Brew one serving
Steep as the pouch says. A 60 g pouch sold as a month works out to about 2 g of tea a day.
- 03
Check your medicines
Hibiscus, beetroot, dandelion and hawthorn can add to blood pressure drugs; green tea lowers nadolol. Ask a pharmacist.

Log and review
Write down home blood pressure readings and weight each week, and review them with your doctor at 30 and 60 days.
The how to use guide goes through each step in more detail.
Medicines
Should you check with a doctor first?
Yes, if you take any regular medicine. Ginger is mild, but the blend also holds hibiscus, beetroot, green tea and ten other names.
Keep taking prescribed medicine; never stop it because of a tea (AHA - Types of BP medications).
More ingredients
Which ingredient should you read about next?
Chamomile is the calming flower in the blend and the last of the six on the brand graphic. Its profile covers allergy risk and a warfarin note. You can also return to the full list of 14 ingredients.
FAQ
Ginger and lemongrass questions people ask
How much ginger is in Cardio Slim Tea?
The amount is not published. The brand graphic names ginger root, but no Supplement Facts panel is shown. A 60 g pouch sold as a month gives about 2 g of tea a day for all 14 ingredients, so the ginger share is likely well under 3 g.
How much ginger a day for blood pressure?
The trials that showed an effect used 3 g of ginger a day or more. Even then, results were clear only in short trials and in people 50 or younger, and the studies disagreed a lot. Talk to your doctor before using ginger for blood pressure.
Does ginger tea cause heartburn?
It can. Heartburn, stomach discomfort, diarrhea and mouth or throat irritation are the side effects the NCCIH lists for ginger. Stronger brews make them more likely. Drinking the tea with a meal may help, and you can stop if symptoms bother you.
What is lemongrass good for?
In teas and cooking, lemongrass is valued for its citrus flavor and scent. We found no human trials of lemongrass for blood pressure or weight in our sources. In Cardio Slim Tea, its main job appears to be taste.
Is lemongrass tea safe to drink every day?
Our sources show no safety issue for lemongrass at normal tea amounts, but they also contain no long-term studies. If you are pregnant, nursing or take regular medicine, ask a doctor before starting any multi-herb tea, and follow the directions on your pouch.
Does Cardio Slim Tea contain garlic?
No. Garlic is not named on the brand graphic or in the sales page list of 14 ingredients. A brand photo shows lemongrass next to garlic, which can confuse readers, but garlic is not part of the published ingredient list.
Does ginger help with weight loss?
Our sources show no clear weight-loss effect for ginger. The NCCIH fact sheet focuses on nausea and stomach side effects. Steady loss of 1 to 2 pounds a week comes from eating, activity and sleep habits, not from a spice in tea.
