Rue Tea: Risks, Uses, and Safe Alternatives

Rue tea (Ruta graveolens) often appears in home remedies and online discussions — but the responsible information must come first: rue tea is not safe to drink.
Scientific reviews and pharmacological monographs describe toxicity, abortion risk, and phototoxic skin reactions associated with the plant and its essential oil. This article explains what rue is, why rue tea should not be consumed, and offers safe herbal alternatives for your wellness ritual — without medical claims. 【Drugs.com】【PubMed】

In Portuguese, “arruda” refers to Ruta graveolens, a member of the Rutaceae family (the same family as citrus fruits). The plant has a strong aroma and a long history of ritual and ornamental use, but from a food safety standpoint, oral ingestion is not recommended. Brazilian and international technical documents list toxicological alerts and botanical identification data, reinforcing the need for caution. 【Brazilian Ministry of Health】

🌿 What Is Rue Tea — and Why It Raises Concerns

The term “rue tea” circulates in old folk recipes, but there is no safety basis for its ingestion.
Modern references describe Ruta graveolens as contraindicated during pregnancy and unsafe for oral use, due to its abortifacient, hepatotoxic, and gastrointestinal irritant properties when consumed in higher doses.
As of 2025, clinical compendiums continue to emphasize:

Avoid rue during pregnancy and breastfeeding — and there is no clinical evidence supporting its oral use. 【Drugs.com】

Beyond ingestion, skin contact with rue or its essential oil can cause phytophotodermatitis — a severe photo-toxic reaction triggered when compounds like furocoumarins (psoralens) meet UV-A light.
Case reports and medical reviews describe blisters, burns, and pigmentation after handling rue followed by sun exposure (or tanning lamps). 【PubMed】【Lippincott】

☕ Rue Tea — Why You Shouldn’t Drink It

Unlike culinary herbs such as ginger, hibiscus, or chamomile, rue is not a food-safe plant.
If your goal is a soothing or relaxing tea ritual, choose herbal infusions with proven safety and proper labeling. Rue should stay out of your cup.

🌼 Traditional and Cultural Uses

In many cultures, rue appears in rituals, incense, or ornamental uses, but not as food.
Technical documents describe its botany and toxicity, but these are not endorsements for making tea — they are safety references explaining why rue should not be used for drinking.
Always interpret traditional mentions as cultural context, not medical advice. 【Brazilian Ministry of Health】

📊 “Nutritional Table” — Why It Doesn’t Apply to Rue

Nutritional labeling (calories, carbs, protein, etc.) applies to edible foods and drinks.
Because rue is not edible, there are no nutritional values listed in TACO or USDA databases.
Instead, official sources focus on toxicology and safety warnings.

Item	Status
Calories, macros, %DV (100 g)	❌ Not applicable — not for ingestion
USDA/TACO listing	❌ Not registered as a food
Technical focus	⚠️ Toxicity, pregnancy/lactation contraindication, phototoxicity

If you’re looking for nutritional charts, refer to safe culinary herbs like ginger, echinacea, or hibiscus — all available on the Nutritive Blog.

🧴 External or Cosmetic Use — Extreme Caution

Even topical use (such as herbal baths, compresses, or oils) can cause skin burns and hyperpigmentation when exposed to sunlight.
Rue contains furocoumarins, which make the skin photosensitive.
If you handle fresh leaves, wear gloves, wash your hands thoroughly, and avoid sun exposure for several hours afterward. 【PubMed】

---

🌱 Storage and Cultivation (If You Grow Rue at Home)

• Always wear gloves when handling the plant.
• Keep away from children and pets.
• Do not use leaves, flowers, or oil for drinking or topical application.
• Remember: many Rutaceae species (citrus family) contain phototoxic compounds — sunlight exposure after contact can trigger burns.

⚠️ Safety, Contraindications, and Risks

• Ingestion: Not recommended — may cause gastric pain, liver toxicity, and severe effects in high doses.
• Pregnancy and lactation: Strictly contraindicated. Documented abortifacient and uterine stimulant effects. 【Drugs.com】【PMC】
• Skin exposure: May cause phytophotodermatitis (burns, blisters, or dark spots). Avoid using rue as a “natural repellent.” 【PubMed】
• Medical conditions: People with liver or kidney diseases, children, and elderly individuals should avoid all use.
• Quality/identification: Even if correctly identified (Ruta graveolens), do not drink rue tea — identification does not make it safe.
