HelloPharmacist Scorecard of Litchi Alcohol Free by Hawaii Pharm

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 seed extract in dried form. Litchi (also called lychee) is a tropical fruit, and this extract concentrates its compounds.

The liquid also includes glycerin and water as inactive ingredients to deliver the extract.

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.

We don't have effectiveness ratings for litchi seed extract in our data. While animal research hints that it may affect blood glucose levels, we can't tell you from the information we hold whether it's actually effective for any particular use in people.

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 as a whole food in normal amounts is generally well tolerated, but concentrated extracts like this one haven't been well studied. Allergic reactions are possible — ranging from mild (hives, skin irritation, swollen lips or tongue) to severe (shortness of breath, anaphylaxis).

There's also a documented concern: a large review linked lychee consumption to a rare but serious condition called hypoglycemic encephalopathy (low blood sugar affecting the brain) in children, especially malnourished ones. The link is debated, but the evidence includes a toxic compound found in their urine.

We don't have enough safety data on extracts during pregnancy or breastfeeding to say either way — talk with your doctor or pharmacist about your individual situation.

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.

If you take antidiabetes drugs (blood sugar medications), check with your doctor or pharmacist first — litchi seed extract may increase the risk of low blood sugar. Also check if you're on any immunosuppressants, since the extract may theoretically reduce their effectiveness.

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 a single-ingredient litchi seed extract. It's most important to check with your doctor or pharmacist if you take any blood sugar medication or immune-suppressing drug before starting it.

If you have a history of allergic reactions to tropical fruits, be cautious. A conversation with your own healthcare provider about whether it fits your health situation is worth having.

Litchi Seed Extract, Dry2 drug types · 207 drugs

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.
