## Overview

Cistus ladanifer is a Mediterranean shrub whose resinous exudate (labdanum) contains polyphenols including monomeric and oligomeric proanthocyanidins, flavonoids, and diterpenes such as labdanolic acid. These compounds are associated with [antioxidant](/ingredients/condition/antioxidant) and [antimicrobial](/ingredients/condition/immune-support) activity, though no clinical trials have been conducted specifically on this species in humans.

## Health Benefits

• No clinical evidence available - traditional use only for this species
• Related species Cistus creticus assessed by EMA for traditional use in cough and cold relief (evidence quality: traditional use only)
• Historically cultivated as medicinal plant (evidence quality: traditional/historical)
• No human clinical trials or RCTs exist for Cistus ladanifer specifically
• Potential benefits remain unsubstantiated by clinical research

## Mechanism of Action

The polyphenolic fraction of Cistus ladanifer, particularly oligomeric proanthocyanidins (OPCs) and flavonoids like kaempferol and quercetin derivatives, scavenges [reactive oxygen species](/ingredients/condition/antioxidant) and inhibits pro-[inflammatory](/ingredients/condition/inflammation) enzymes such as cyclooxygenase (COX). Diterpenic compounds including labdanolic acid and its derivatives may interact with microbial membrane integrity, contributing to observed in vitro [antimicrobial](/ingredients/condition/immune-support) effects. The related compound cistifolin has shown inhibition of NF-κB signaling in cell-based models, though direct evidence for Cistus ladanifer-specific compounds acting via this pathway in humans is lacking.

## Clinical Summary

No clinical trials have been conducted specifically on Cistus ladanifer in human subjects, placing all health claims in the category of traditional use only. The closely related species Cistus creticus (rock rose) has been assessed by the European Medicines Agency (EMA) and granted traditional herbal medicinal product status for symptomatic relief of mild upper respiratory tract conditions such as cough and cold, based on at least 30 years of traditional use rather than controlled trial evidence. In vitro and animal studies on Cistus ladanifer extracts have demonstrated [antioxidant](/ingredients/condition/antioxidant) and [antimicrobial](/ingredients/condition/immune-support) properties, but these findings have not been validated in randomized controlled trials. The overall evidence base is weak, and efficacy in humans cannot be confirmed from existing data.

## Nutritional Profile

Cistus ladanifer (Labdanum/Rock Rose) is not a food ingredient and thus lacks conventional macronutrient or caloric nutritional data. Its profile is defined entirely by its phytochemical and bioactive compound composition. Key documented constituents include: Polyphenols — predominantly labdanum-type diterpene acids (labdanolic acid, acetyl labdanolic acid) at concentrations of 15–30% of resinous exudate dry weight; Flavonoids — kaempferol, quercetin, myricetin, and their glycosides identified in leaf extracts at approximately 0.5–2.5% dry weight of leaf material; Proanthocyanidins (condensed tannins) — present at 3–8% dry weight in leaves, contributing astringent properties; Phenolic acids — gallic acid, ellagic acid, caffeic acid at trace-to-moderate concentrations (0.1–0.8% dry weight); Monoterpenes and sesquiterpenes in essential oil — α-pinene (10–25%), camphene (2–8%), borneol (1–5%), viridiflorol (1–6%), and ledol; Labdanoid diterpenes — labdanol, sclareol, and related compounds comprising up to 10–20% of resin fraction; Acetophenone derivatives unique to the species. No meaningful dietary fiber, protein, fat, or carbohydrate content is documented as it is used exclusively as a resinous extract or essential oil, not as a whole food. Bioavailability: polyphenol absorption is expected to be moderate and variable, consistent with other plant polyphenols (typically 5–20% systemic absorption), though no pharmacokinetic studies exist specifically for this species.

## Dosage & Preparation

No clinically studied dosage ranges are available for Cistus ladanifer extracts, powders, or standardized forms, as no clinical studies exist. For the related Cistus creticus, EMA specifies comminuted herbal substance as herbal tea (decoction) for oral use, though exact dosing details are not provided. Consult a healthcare provider before starting any new supplement.

## Safety & Drug Interactions

Cistus ladanifer has no well-documented clinical safety profile due to the absence of human trials; adverse effects observed are largely anecdotal or extrapolated from in vitro data. Labdanum resin and its volatile components may cause contact dermatitis or allergic reactions, particularly in individuals sensitive to Cistaceae family plants or fragrance compounds. No established drug interactions have been identified, but the flavonoid content theoretically could interfere with cytochrome P450 enzymes (particularly CYP3A4) at high supplemental doses, potentially affecting drugs with narrow therapeutic windows. Use during pregnancy and breastfeeding is not recommended due to the complete absence of safety data in these populations.

## Scientific Research

No human clinical trials, RCTs, or meta-analyses are reported for Cistus ladanifer in available research databases; no PubMed PMIDs are available. The related species Cistus creticus has been assessed by EMA/HMPC under traditional use only (not well-established use), with assessment finalized for cough and cold (28/01/2014), but without supporting clinical studies.

## Historical & Cultural Context

Cistus ladanifer has been cultivated historically as a medicinal plant in the Mediterranean region, though specific traditional medicine systems and duration of use are not detailed. The plant has been valued for centuries as a source of labdanum resin for perfume and incense production.

## Frequently Asked Questions

### What is Cistus ladanifer used for traditionally?

Cistus ladanifer has been cultivated historically around the Mediterranean basin primarily as a source of labdanum resin, used in perfumery and traditional medicine. Ethnobotanically, the plant was applied topically for wound healing and taken internally for respiratory complaints, though these uses have never been evaluated in clinical trials. Its traditional medicinal status is distinct from the EMA-recognized Cistus creticus, which holds formal traditional herbal registration for cold and cough relief.

### What are the active compounds in Cistus ladanifer?

The main bioactive compounds in Cistus ladanifer include labdanolic acid and related labdane diterpenes found in its resinous exudate, along with polyphenols such as myricetin, quercetin, kaempferol glycosides, and oligomeric proanthocyanidins (OPCs) concentrated in leaves and stems. The essential oil fraction contains monoterpenes like α-pinene and camphene, as well as sesquiterpenes. These compounds collectively account for the plant's in vitro antioxidant DPPH-scavenging activity, with IC50 values reported in some studies between 20–80 µg/mL depending on extract preparation.

### Is Cistus ladanifer the same as Cistus creticus or rock rose?

No, Cistus ladanifer (labdanum rockrose or gum cistus) and Cistus creticus (pink rockrose) are distinct species within the Cistaceae family with overlapping but not identical phytochemical profiles. Cistus creticus is the species formally evaluated by the EMA for traditional use in upper respiratory complaints, and it is notably richer in the polyphenol cistifolinoside. Cistus ladanifer is more commonly associated with labdanum resin production for the fragrance industry, and its specific medicinal properties have received less scientific attention than those of Cistus creticus.

### Are there any clinical studies on Cistus ladanifer supplements?

As of current available evidence, no published randomized controlled trials or significant human clinical studies have been conducted specifically on Cistus ladanifer extracts or supplements. Most research consists of in vitro assays measuring antioxidant capacity, antibacterial activity against pathogens like Staphylococcus aureus and Escherichia coli, and cytotoxicity screening. Any health claims on commercial supplements referencing this species rest entirely on traditional use and in vitro findings, which cannot reliably predict clinical outcomes in humans.

### What is the recommended dosage of Cistus ladanifer?

There is no established or clinically validated dosage for Cistus ladanifer, as no human pharmacokinetic or dose-finding studies have been performed. Some commercial products standardized to polyphenol content use doses in the range of 500–1000 mg of dried extract per day, borrowing loosely from dosing conventions established for the related Cistus creticus in European herbal practice. Without clinical data supporting efficacy or safety at any specific dose, no evidence-based dosage recommendation can be made for Cistus ladanifer.

### Is Cistus ladanifer safe to use during pregnancy or while breastfeeding?

There is no clinical safety data available for Cistus ladanifer use during pregnancy or breastfeeding, as this species lacks human studies. Due to the absence of safety evidence specific to pregnant or nursing women, it is advisable to avoid use during these periods unless directed by a healthcare provider. Related Cistus species have only traditional use documentation, which does not establish modern safety standards for vulnerable populations.

### Does Cistus ladanifer interact with medications I might be taking?

There are no documented drug interaction studies for Cistus ladanifer, as clinical research on this species is absent. Without human trials or pharmacokinetic data, potential interactions with common medications cannot be reliably assessed. If you are taking medications, consult your healthcare provider before adding Cistus ladanifer supplements to ensure safety.

### What is the difference between Cistus ladanifer and other Cistus species used as supplements?

Cistus ladanifer is a distinct species that historically was cultivated as a medicinal plant but lacks modern clinical evidence of efficacy. Cistus creticus (also called rock rose) has been formally assessed by the EMA for traditional use in cough and cold relief, giving it some regulatory recognition for traditional applications. While both species share traditional use in Mediterranean medicine, only Cistus creticus has undergone EMA monograph evaluation, making it the better-documented option for traditional use claims.
