HelloPharmacist Scorecard of Litchi by Herbal Terra

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: litchi dried seed liquid extract. The extract is prepared using menstruum, a liquid used in herbal preparation, as the inactive ingredient.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Lychee product and its label doesn't state a use — see Lychee's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The product facts we hold don't include effectiveness ratings for lychee seed extract against any health condition, so we can't tell you what research supports its use.

The evidence, ingredient by ingredient Lychee

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Lychee fruit in normal food amounts is likely fine, but concentrated extracts like this one haven't been well studied. The safety data doesn't establish whether extracts are safe during pregnancy or breastfeeding—talk with your doctor or pharmacist for personalized advice if you're pregnant, planning pregnancy, or nursing.

Orally, lychee can cause allergic reactions ranging from mild (itching, rash, tongue or lip swelling) to severe (shortness of breath, anaphylaxis). There's also a documented association between lychee consumption and low blood sugar with brain inflammation (hypoglycemic encephalopathy), particularly in children who are malnourished, though this link has been questioned.

Contact with the raw fruit can trigger allergic contact dermatitis on the skin.

Side effects, ingredient by ingredient Lychee

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Lychee.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 207 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check with your doctor or pharmacist before using this product if you take antidiabetes drugs (blood sugar medications), where lychee seed may increase low blood sugar risk. Also flag immunosuppressants (medications that weaken your immune system), where lychee might theoretically reduce effectiveness—though this hasn't been seen in humans yet.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product is for someone looking to use lychee seed extract as a supplement, but it's not well studied in concentrated form. If you take diabetes or immune-suppressing medications, talk with your doctor or pharmacist before adding it—the interactions could affect how your drugs work.

Anyone with a history of allergic reactions to lychee should avoid it.

Antidiabetes Drugs

Theoretically, lychee seed might increase the risk of hypoglycemia when used with antidiabetes drugs.
Animal research suggests that an aqueous extract of lychee seed reduces fasting and 2-hour postprandial blood glucose and improves impaired glucose tolerance in rats with type 2 diabetes. Additionally, retrospective research in children has found an association between lychee consumption and increased odds of acute hypoglycemic encephalopathy.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, lychee might reduce the effectiveness of immunosuppressant drugs.
In vitro, flavonoids extracted from lychee show immunostimulant effects. So far, this effect has not been reported in humans.

Litchi by Herbal Terra: Common Questions

Does Litchi by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Litchi has a known interaction with 207 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Litchi contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this if I have type 2 diabetes?
Not without talking to your doctor first. Animal research suggests lychee seed extract can lower blood sugar, so combining it with your diabetes medication could increase the risk of low blood sugar (hypoglycemia). Your doctor or pharmacist needs to know before you start.
Is lychee safe to eat as a fruit if I take diabetes medication?
Yes, lychee fruit in normal food amounts is generally considered safe. The concern is specifically with concentrated extracts like this product, which haven't been well studied.
Can I use this while I'm pregnant or breastfeeding?
There isn't enough safety data on lychee extracts during pregnancy or breastfeeding. Talk with your doctor or pharmacist—they can help you decide what's right for your situation.
What kind of allergic reactions can lychee cause?
Reactions range from mild (itching, rash, swelling of the tongue or lips) to severe (shortness of breath, anaphylaxis). Some people also get allergic contact dermatitis from touching the raw fruit. If you've had an allergic reaction to lychee before, avoid this product.
I take an immunosuppressant for my transplant. Is this safe?
Test-tube studies suggest lychee flavonoids might stimulate immune activity, which could theoretically make your medication less effective, though this hasn't been proven in people. Check with your transplant team or pharmacist before using it.
