HelloPharmacist Scorecard of Orange 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
This product contains one active ingredient: certified organic orange dried peel liquid extract. Orange peel has a long history in herbal traditions, though the science behind what it does is still catching up.
The only other ingredient listed is menstruum, which is the liquid used to extract and preserve the orange peel.
Does it work?
Couldn't assess
The evidence we hold doesn't support claims that orange extract works for asthma, prostate cancer, the common cold, constipation, depression, or pre-procedural anxiety. For each of these, the research simply isn't there yet, or what exists isn't reliable enough to rate.
If you're considering this product for one of those reasons, we can't say whether it'll help based on the data available.
How safe is it?
Well-documented data
Orange fruit and juice are safe as everyday food for most people. However, this is a concentrated extract, not whole fruit, and concentrated orange supplements and essential oils haven't been studied as thoroughly as the fruit itself — so the cautious approach is warranted.
There have been reports of belly cramps (intestinal colic) in children who swallowed large amounts of orange peel, so keep this out of reach of kids and stick to recommended doses. The safety data suggest it's likely safe in pregnancy and while breastfeeding, but if you're pregnant or nursing, talk with your doctor or pharmacist about whether this product makes sense for you.
Meds to double-check
Major interaction found
Before taking this product, check with your doctor or pharmacist if you're on pravastatin, ivermectin, celiprolol, OATP substrates, P-glycoprotein substrates, quinolone antibiotics, or fexofenadine. All of these have documented Major or Moderate interactions with orange extract that can affect how your medications work.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.
Orange extract is generally well tolerated as a food, but this concentrated version interacts with a lot of medications — especially heart and cholesterol drugs, antibiotics, and allergy medicines. We don't yet have solid evidence it works for the conditions it's often used for.
If you take any prescription medication, check it against this product with your pharmacist or doctor before you start.

Orange by Herbal Terra Drug Interactions
HelloPharmacist Interaction Report
Herbal Terra Orange contains certified organic orange peel extract, which interacts with a significant number of medications.
The most serious concern is with pravastatin (a cholesterol drug), which can reach dangerously high blood levels when taken with orange extract — we're talking levels jumping by around 149%. You'll also want to avoid taking this product with ivermectin (an antiparasitic), celiprolol (a heart medication), or certain OATP substrates (a broad class of drugs transported by your cells), all of which can lose effectiveness or have reduced absorption.
Read the full breakdown — every affected drug type, severity by severity
Moderate interactions occur with P-glycoprotein substrates (drugs moved by a transport protein in your gut and body), quinolone antibiotics (if the orange juice is calcium-fortified), and fexofenadine (an allergy medication), which can see bioavailability drop by as much as 72%. If you're on any of these medications, spacing out doses by at least 4 hours may help, though you'll want to confirm the specifics with your doctor or pharmacist.
Altogether, these interactions span 246 individual medications. Check your exact prescriptions with the search tool on this page before you start.

For each ingredient in Orange with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
certified organic Orange dried peel liquid extract
Celiprolol (Celicard)
Consuming sweet orange with celiprolol can decrease oral absorption of celiprolol.
A pharmacokinetic study in healthy volunteers shows that celiprolol levels, after a single dose of 100 mg, are decreased by up to 90% in people who drink sweet orange juice 200 mL three times daily. It's not known if lower consumption of sweet orange juice will have the same effect. Theoretically, this occurs due to short-term inhibition of organic anion transporting polypeptide (OATP). Recommend separating drug administration and consumption of sweet orange by at least 4 hours.
Ivermectin (Stromectol, Others)
Consuming sweet orange juice with ivermectin can decrease the oral absorption of ivermectin.
A pharmacokinetic study in healthy volunteers shows that taking ivermectin orally with sweet orange juice 750 mL over 4 hours reduces the bioavailability of ivermectin. This effect does not seem to be related to effects on P-glycoprotein. The effect on ivermectin is more pronounced in males compared to females.
Organic Anion-Transporting Polypeptide Substrates (Oatp)
Consuming sweet orange juice can decrease oral absorption of OATP substrates. Separate administration by at least 4 hours.
Clinical research shows that consuming sweet orange juice inhibits OATP, which reduces bioavailability of oral drugs that are substrates of OATP. For example, sweet orange juice decreases bioavailability of fexofenadine, a substrate of OATP, by about 72% and of celiprolol, another OATP substrate, by up to 90%. Since sweet orange juice seems to affect OATP for a short time, recommend separating drug administration and consumption of sweet orange juice by at least 4 hours.
Pravastatin (Pravachol)
Consuming sweet orange juice with pravastatin can increase the absorption of pravastatin.
A small pharmacokinetic study in healthy volunteers shows that consuming sweet orange juice 800 mL over 3 hours, including before, during, and after taking pravastatin 10 mg, increases pravastatin levels by about 149%, without affecting pravastatin elimination. Theoretically this effect might be due to modulation of organic anion transporting polypeptides (OATPs) by sweet orange juice. Sweet orange juice does not seem to affect simvastatin levels, but it is not known if sweet orange affects any of the other statins.
Fexofenadine (Allegra)
Consuming sweet orange juice with fexofenadine can decrease oral absorption of fexofenadine.
Clinical research shows that coadministration of sweet orange juice 1200 mL decreases bioavailability of fexofenadine by about 72%. In an animal model, sweet orange juice decreased bioavailability of fexofenadine by 31%. Fexofenadine manufacturer data indicates that concomitant administration of sweet orange juice and fexofenadine results in larger wheal and flare sizes in research models. This suggests that sweet orange reduces the clinical response to fexofenadine. Theoretically, this occurs due to short-term inhibition of organic anion transporting polypeptide (OATP). Recommend separating drug administration and consumption of sweet orange by at least 4 hours.
P-Glycoprotein Substrates
Sweet orange juice seems to modulate P-glycoprotein (P-gp), which might affect the blood levels of P-gp substrates.
Animal and in vitro research suggest that orange juice extract inhibits drug efflux by P-gp, increasing absorption and levels of P-gp substrates. In contrast, pharmacokinetic research in humans shows that drinking large amounts of sweet orange juice decreases absorption and levels of the P-gp substrate celiprolol. This suggests that orange juice actually induces drug efflux by P-gp or affects drug levels by another mechanism such as inhibiting the gut drug transporter called organic anion transporting polypeptide (OATP). Until more is known, sweet orange juice should be used cautiously in people taking P-gp substrates.
Quinolone Antibiotics
Calcium-fortified sweet orange juice might reduce quinolone absorption.
Calcium binds to quinolones in the gut. Theoretically, the calcium in certain fortified orange juices can also bind to quinolone antibiotics and reduce their absorption and levels.
