Cabbage Drug Interactions: The Bottom Line

From the HelloPharmacist Editorial Team · Updated July 2026

Based on the available evidence, the overall risk of a clinically significant Cabbage drug interaction appears low for most people. None of the listed interactions are rated major, and even the best-studied ones showed only modest changes in drug levels.

Interactions deserving the most attention

The interaction that deserves the most respect involves warfarin. Cabbage contains vitamin K, and eating large amounts could work against this blood thinner, where small changes matter. Human studies also show that regular cabbage intake can lower levels of acetaminophen and oxazepam somewhat, likely because cabbage speeds up a pathway the body uses to clear them, though the drops seen were small. For people on diabetes medications, cabbage might in theory add to blood sugar lowering, but this comes from animal and lab research only.

What the rest of the list means

The long list of medications looks worrying, but most entries come from one theory: cabbage may stimulate pathways the body uses to break down and clear many drugs. Much of this is based on animal or lab research, and where the effect has been measured in people, the changes were modest and unlikely to matter for most medicines.

What Severity, Likelihood & Evidence Mean

Severity — How Serious It Can Be

  • Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
  • Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
  • Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
  • No known interaction. Checked against our sources with nothing documented — not the same as proven safety.

Likelihood — How Well It’s Documented

  • Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
  • Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
  • Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Where This Data Comes From

  • Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.
  • Each drug listed above links to the full report for that exact Cabbage combination — clinical detail, likelihood, evidence level, and citations.
  • Content is reviewed by licensed HelloPharmacist pharmacists — see our data sources and editorial standards.

Cabbage: Uses, Safety & Side Effects

The bottom line

Cabbage is a nutritious, low-calorie vegetable that is safe to eat as food and is sometimes applied to the skin as a leaf wrap for breast engorgement or sore joints. Most medicinal claims are based on tradition or limited research, with the strongest (though still modest) evidence being for cooling cabbage leaves on engorged breasts. Talk to your pharmacist or doctor before using cabbage in large amounts or as a treatment.

Overview

Cabbage is a leafy green vegetable that belongs to the Brassicaceae (mustard) family, which also includes broccoli, kale, cauliflower, and Brussels sprouts. Common types include green, red, and Napa (Chinese) cabbage. It is grown widely around the world in cooler climates and has been a staple food for centuries.

Cabbage is rich in vitamin C, vitamin K, folate, and fiber, and it contains plant antioxidants. Most people eat it raw, cooked, or fermented (such as sauerkraut or kimchi). Beyond food, cabbage has a long history in folk medicine, where chilled or crushed leaves are applied to the skin for swelling, and the vegetable or its juice is used for stomach complaints.

How it works

Cabbage contains vitamins (especially C and K), fiber, and antioxidant plant compounds. Like other cruciferous vegetables, it provides glucosinolates, which the body can convert into substances such as sulforaphane and indoles. Laboratory and animal studies suggest these compounds may have antioxidant and anti-inflammatory activity.

For topical use, the proposed benefit of a cabbage leaf wrap may come partly from the cooling effect and from compounds in the leaf that could reduce swelling. It is worth noting that much of this is based on lab research or tradition, and these effects have not been clearly proven in people.

Safety & precautions

Cabbage is safe and healthy for most people when eaten as a food. Concentrated supplements, extracts, or very large medicinal amounts are less well studied.

People with thyroid conditions should be aware that large amounts of raw cruciferous vegetables contain goitrogens, substances that may affect thyroid function, especially if iodine intake is low. Cooking reduces this effect, and normal dietary amounts are generally not a concern.

Pregnancy: Cabbage is fine to eat as a normal part of the diet during pregnancy. Concentrated supplements or large medicinal doses have not been well studied, so it is best to avoid them unless your provider approves.

Breastfeeding: Cabbage is safe to eat while breastfeeding. Chilled cabbage leaves are sometimes applied to the breasts for engorgement, but check with a lactation consultant or doctor first, since overuse has been reported to reduce milk supply in some cases.

Side effects

For most people, cabbage causes few problems beyond gas, bloating, or stomach discomfort, especially when eaten raw or in large amounts. Fermented forms like sauerkraut are high in salt.

Applied to the skin, cabbage leaves are usually well tolerated, but some people may notice mild skin irritation. Allergic reactions to cabbage are uncommon but possible. Stop use and seek care if you develop a rash, itching, or swelling.

Cabbage: Reported Adverse Effects

Documented safety reports on Cabbage from the evidence-graded Natural Medicines (TRC Healthcare) database, shown word-for-word from the licensed record.

Reports by condition
Dermatitis Immunologic

Topically, cabbage may cause contact dermatitis. Allergic reactions to cabbage-related vegetables are rare. However, anaphylactic reactions to broccoli and cauliflower have been reported. Because the surface proteins believed to cause allergic reactions to brocolli are also found in cabbage, some patients allergic to brocolli or other vegetables in the Brassicaceae family may also be allergic to cabbage.

Herpes zoster (shingles) Dermatologic

Some preliminary clinical research shows that application of cabbage leaf wraps to knee joints for at least 2 hours daily for 4 weeks is generally well-tolerated. Of the 27 patients using cabbage leaf wraps in this study, one patient reported an itching and burning sensation during the application. This patient was later found to have shingles, which may explain the adverse event. However, in another case, a patient applying fresh Savoy cabbage leaves on his knee to reduce joint pain reported pain and burning after 4 hours of use. Skin patch and prick tests did not indicate an allergic reaction, and the patient's lesion improved with wet dressings, topical antibiotics, and oral antibiotics.

Dosing

There is no standardized medicinal dose for cabbage. As a food, it can be eaten freely as part of a balanced diet.

For breast engorgement, a common traditional approach is to apply clean, chilled cabbage leaves to the breasts for a limited time and remove them once they wilt or symptoms ease. For supplements or juice, follow the product label. Because effective and safe doses are not well established, check with your pharmacist or doctor before using cabbage as a treatment.

Do Cabbage leaves really help with breast engorgement?
Chilled Cabbage leaves are a popular remedy and some studies suggest they may ease discomfort and swelling, though the benefit may be similar to other cooling methods. Ask a lactation consultant before using them often.
Can I eat Cabbage during pregnancy?
Eating Cabbage as a normal food is fine during pregnancy. Concentrated Cabbage supplements or large medicinal amounts are not well studied, so avoid those unless your provider approves.
Why does Cabbage cause gas?
Cabbage contains fiber and certain sugars that gut bacteria ferment, which can produce gas and bloating. Cooking it and eating smaller portions may help reduce this.
