HelloPharmacist Scorecard of Rosehips 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
This product contains one active ingredient: rose hip seed extract from the rose hip plant. Rose hips are the fruit of the rose plant and have been used traditionally for their vitamin C content and other compounds.
The extract is suspended in a liquid base made of alcohol, water, and glycerin.
Does it work?
Moderate evidence
Rose hip has possibly effective evidence for helping with postoperative pain (pain after surgery). It's also possibly effective for osteoarthritis.
For high cholesterol (hyperlipidemia), the evidence we hold is insufficient to rate whether it works. Talk with your doctor about whether rose hip fits your particular situation.
How safe is it?
Well-documented data
Rose hip from common varieties is generally well tolerated as a food, but supplement safety at concentrated doses is less studied than we'd like. The most common side effects reported are flatulence and loose stools.
Less commonly, people have reported vertigo, headache, and various digestive issues—though in most studies these happened just as often in people taking placebo. Because there isn't enough reliable safety data on supplement doses specifically, use caution and avoid concentrated supplements unless your doctor approves.
Meds to double-check
Moderate interaction found
Before taking this product, double-check with your doctor or pharmacist if you take estrogens (birth control or hormone replacement), blood thinners or antiplatelet drugs, lithium, any chemotherapy drugs, or aluminum-containing supplements. Rose hip may theoretically affect how all of these work.
These are moderate-severity concerns worth clarifying before you start.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
Rose hip may help with postoperative pain or osteoarthritis, but it interacts with several medication types—most importantly estrogens, blood thinners, lithium, and some chemotherapy drugs. If you take any prescription medications, especially hormonal birth control, blood thinners, or mood stabilizers, talk it through with your doctor or pharmacist before starting.
It's generally well tolerated, but the safety data at supplement doses is limited.

Rosehips by Hawaii Pharm Drug Interactions
HelloPharmacist Interaction Report
Hawaii Pharm's Rosehips liquid contains rose hip seed extract, which has documented interactions with a number of medications.
The most serious concern is with estrogens—including birth control pills and hormone replacement therapy—where rose hip's vitamin C content may theoretically raise estrogen levels in your blood by up to 55% in some situations.
Read the full breakdown — every affected drug type, severity by severity
Rose hip also interacts with blood thinners and antiplatelet drugs (like warfarin and aspirin), though the vitamin C amount in this product is thought too low to cause major problems with aspirin or warfarin specifically. It may theoretically reduce how well these drugs work.
Additionally, if you take lithium for mood disorders, rose hip's diuretic properties might increase lithium levels, potentially requiring a dose adjustment. Because rose hip contains antioxidants, there's theoretical concern it could interfere with certain chemotherapy drugs—alkylating agents and antitumor antibiotics—though the practical impact isn't clear.
Finally, rose hip may increase how much aluminum your body absorbs if you take aluminum-containing products; spacing doses several hours apart can help. Altogether, these interactions span 213 individual medications.

Rose Hip Seed Extract, Dry
Alkylating Agents
Theoretically, the antioxidant effects of rose hip might reduce the effectiveness of alkylating agents but might also reduce the oxidative damage caused by certain alkylating agents.
Rose hip contains vitamin C. The use of antioxidants like vitamin C during chemotherapy is controversial. There is concern that antioxidants could reduce the activity of chemotherapy drugs that generate free radicals, such as cyclophosphamide, chlorambucil, carmustine, busulfan, and thiotepa. In contrast, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. Further, some animal research suggests that the antioxidant effects of rose hip might attenuate cyclophosphamide-induced testicular toxicity. More evidence is needed to determine what effect, if any, antioxidants found in rose hip, such as vitamin C, have on the effectiveness and adverse effects of chemotherapy.
Aluminum
Theoretically, rose hip might increase the amount of aluminum absorbed from aluminum compounds.
Rose hip contains vitamin C. Theoretically, vitamin C increases the absorption of aluminum. Concomitant use might increase aluminum absorption, but the clinical significance of this is unknown. Administer rose hip two hours before or four hours after antacids.
Anticoagulant/Antiplatelet Drugs
Theoretically, rose hip might reduce the effectiveness of anticoagulant or antiplatelet drugs.
In vitro and animal research suggests that a constituent of rose hip, rugosin E, can induce platelet aggregation. This has not been shown in humans. Theoretically, concomitant use of rose hip might reduce the effectiveness of antiplatelet or anticoagulant drugs.
Antitumor Antibiotics
Theoretically, the antioxidant effects of rose hip might reduce the effectiveness of antitumor antibiotics.
Rose hip contains the antioxidant vitamin C. There is concern that antioxidants might reduce the activity of chemotherapy drugs that generate free radicals, such as antitumor antibiotics. In contrast, other researchers theorize that antioxidants might make antitumor antibiotic chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effects, if any, antioxidants such as vitamin C have on antitumor antibiotic chemotherapy.
Estrogens
Theoretically, rose hip might increase blood levels of estrogens.
Rose hip contains vitamin C. Increases in plasma estrogen levels of up to 55% have occured under some circumstances when vitamin C is taken concurrently with oral contraceptives or hormone replacement therapy, including topical products. It is suggested that vitamin C prevents oxidation of estrogen in the tissues, regenerates oxidized estrogen, and reduces sulfate conjugation of estrogen in the gut wall. When tissue levels of vitamin C are high, these processes are already maximized and supplemental vitamin C does not have any effect on estrogen levels. However, increases in plasma estrogen levels may occur when women who are deficient in vitamin C take supplements.
Lithium
Theoretically, rose hip might increase blood levels of lithium.
Rose hip is thought to have diuretic properties. Theoretically, due to these potential diuretic effects, rose hip might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.
Aspirin
Theoretically, rose hip might reduce the clearance of aspirin; however, its vitamin C content is likely too low to produce clinically significant effects.
Rose hip contains vitamin C. It has been suggested that acidification of the urine by vitamin C can decrease the urinary excretion of salicylates, increasing plasma salicylate levels. However, short-term use of up to 6 grams daily of vitamin C does not seem to affect urinary pH or salicylate excretion. The vitamin C content of rose hip is typically about 500 mg per 100 grams. Thus, a clinically significant interaction between rose hip and aspirin is unlikely.
Warfarin (Coumadin)
Theoretically, rose hip might reduce the effectiveness of warfarin; however, its vitamin C content is likely too low to produce clinically significant effects.
Rose hip contains vitamin C. High doses of vitamin C may reduce the response to warfarin, possibly by causing diarrhea and reducing warfarin absorption. This occurred in two people who took up to 16 grams daily of vitamin C, and resulted in decreased prothrombin time. Lower doses of 5-10 grams daily of vitamin C can also reduce warfarin absorption, but this does not seem to be clinically significant. The vitamin C content of rose hip is typically about 500 mg per 100 grams. Thus, a clinically significant interaction between rose hip and warfarin is unlikely.
