Rosa Gallica Herb (Rosa gallica): Benefits, Dosage, Safety & Evidence

Questions fréquentes

How does Rosa gallica work medicinally in the body?

Rosa gallica exerts its medicinal effects through several bioactive compounds including geraniol, citronellol, nerol, and quercetin. These constituents provide antioxidant activity by neutralizing free radicals and reducing oxidative stress. The flavonoid quercetin contributes anti-inflammatory properties by modulating inflammatory pathways. Additionally, the tannins present in rose petals create an astringent effect, helping to tone and tighten tissues. These mechanisms support its traditional use for skin conditions, digestive issues, and cardiovascular health, though clinical evidence remains limited (Evidence Level C).

Does Rosa gallica interact with any medications?

Currently, there are no established drug interactions for Rosa gallica in medical literature. The herb has a long history of traditional use without documented adverse interactions with pharmaceuticals. However, due to limited clinical research (Evidence Level C), individuals taking prescription medications should consult a healthcare provider before use. Those on anticoagulants or cardiovascular medications should exercise particular caution, as the herb's effects in combination with these drugs have not been thoroughly studied.

What is the recommended dosage for Rosa gallica?

The traditional adult dosage for Rosa gallica is 2-4 grams of dried petals prepared as a tea, consumed up to three times daily. For topical applications, rosewater can be applied directly to the skin or used as an eyewash. These recommendations are based on traditional use rather than clinical trials (Evidence Level C). Users should start with lower doses to assess tolerance. Consult a qualified medical herbalist for personalized dosing guidance.

Is Rosa gallica safe to use during pregnancy and breastfeeding?

Rosa gallica is generally considered safe during pregnancy and breastfeeding when used in recommended amounts. The herb has an extensive history of traditional use without reported toxicity to mother or child. Rosewater and rose petal tea are commonly used during pregnancy in various cultures. However, pregnant women should avoid concentrated essential oil preparations. As with any herbal remedy, pregnant or breastfeeding individuals should consult a healthcare provider before use (Evidence Level C/Traditional).

What are the skin benefits of Rosa gallica?

Rosa gallica offers notable skin benefits due to its astringent, anti-inflammatory, and antioxidant properties. Traditionally used as a skin tonic, it helps tighten tissues, reduce minor inflammation, and soothe irritation. The quercetin content provides antioxidant protection against environmental damage. Rosewater derived from Rosa gallica can be applied topically as a gentle toner or facial mist. These applications are supported by traditional knowledge and phytochemical analysis rather than extensive clinical trials (Evidence Level C/Traditional).

What side effects can Rosa gallica cause?

Rosa gallica is well-tolerated by most individuals, with side effects being rare. The primary potential adverse reaction is allergic sensitivity, which may cause skin irritation or digestive upset in susceptible individuals. No serious adverse effects have been documented in traditional use. Those with known allergies to roses or plants in the Rosaceae family should exercise caution. If any adverse reaction occurs, discontinue use and consult a healthcare provider (Evidence Level C/Traditional).

Résumé

Rosa gallica is a medicinal plant species used for culinary and therapeutic purposes, exhibiting antioxidant, anti-inflammatory, and skin-protective properties [PMID:34829534, PMID:33478154].

Contexte

Rosa gallica L. is a species of the Rosaceae family, often referred to as the 'pharmacist's rose' [PMID:16217909, PMID:33478154]. It is an allopolyploid plant used as raw material for essential oils, hydrolates, and extracts [PMID:41992043, PMID:33478154].

Usages traditionnels

It has been used widely since the 13th century as a medicinal plant for herbal medicines [PMID:31431930] and is used in China as a crude drug known as 'Mei-gui Hua' and as an ingredient for herbal tea [PMID:20467822, PMID:29188415].

Composés actifs

Active components include flavonoids (flavones, flavonols), polyphenols, anthocyanins, and hydrolysable tannins [PMID:33478154, PMID:30510758, PMID:20232167]. Specific identified compounds include gallic acid, cyanidin-3,5-O-diglucoside, methyl gallate, kaempferol, and quercetin [PMID:34829534, PMID:36573713, PMID:32031983]. Rosehips of R. gallica are rich in ascorbic acid, carotenoids, and phenolic compounds [PMID:37631190, PMID:37238770].

Mécanisme d'action

Anti-skin aging effects are mediated by gallic acid targeting the c-Raf/MEK/ERK/c-Fos signaling axis [PMID:34829534]. Skin whitening and anti-wrinkle activities are associated with the regulation of MAPK activation and suppression of MMP-1 levels [PMID:32609563]. Skin hydration is improved via the GLK signaling pathway and increased HAS2 and hyaluronic acid levels [PMID:36573713]. Anti-inflammatory effects involve the reduction of the MAPK signaling pathway and downregulation of COX-2 [PMID:30510758].

Preuves cliniques

Preuve BSkin Brightness

Treatment with a Rosa gallica petal extract (RPE) formulation significantly enhanced skin brightness (L* value) in volunteers [PMID:32609563]

Preuve BSkin Hydration

A double-blinded clinical study demonstrated that RPE treatment significantly improved hydration levels in human skin [PMID:36573713]

Preuve DUVB-Induced Skin Aging

Oral administration in mice prevented UVB-mediated skin wrinkle formation and loss of collagen/keratin fibers [PMID:34829534]

Preuve DChronic Stress

In mice subjected to chronic stress, R. gallica extract reduced the decrease in activity compared to controls, though no significant effect was seen in non-stressed mice [PMID:31431930]

Preuve DLung Adenocarcinoma (A549 cells)

RPE inhibited growth, migration, and invasion of A549 cells via EGFR-MAPK and mTOR-Akt signaling pathways [PMID:33158043]

Sécurité et effets indésirables

Hydrosols (6, 14, 20%) showed low genotoxicity in human lymphocyte and barley test systems and had no cytotoxic effect on barley [PMID:38794227].

Synthèse des preuves

Evidence is primarily based on in vitro studies and animal models (Level D), with limited clinical trials (Level B) focusing on topical skin applications for hydration and brightness.
