Helichrysum arenarium (Helichrysum arenarium): Benefits, Dosage, Safety & Evidence

Questions fréquentes

How does Helichrysum arenarium work for liver health?

Helichrysum arenarium primarily works through choleretic and hepatoprotective mechanisms. The active compounds, specifically flavonoids like naringenin and chalcones such as isosalipurposide, stimulate bile production and flow from the liver. This action aids in digestion and the elimination of toxins. Additionally, these compounds exhibit antioxidant properties that help protect liver cells from damage. While these mechanisms are supported by in vitro and animal studies, clinical evidence remains limited (Evidence Level C).

Does Helichrysum arenarium interact with any medications?

Due to its potential effects on liver enzymes and bile flow, Helichrysum arenarium may interact with medications metabolized by the liver. Because it stimulates bile secretion, it could theoretically alter the absorption or excretion of certain drugs. Patients taking anticoagulants or medications for gallbladder disease should exercise caution. There is currently limited specific data on clinical drug interactions (Evidence Level D), so it is essential to consult a healthcare provider before combining this herb with prescription medications.

What is the recommended dosage for Helichrysum arenarium?

The standard adult dosage for Helichrysum arenarium depends on the preparation. For a tea, use 3 to 5 grams of dried flowers daily. If using a liquid tincture, the typical dose is 2 to 3 ml taken up to three times daily. These dosages are based on traditional use and pharmacopoeial standards (Evidence Level C) rather than rigorous clinical trials. Always follow specific product instructions or consult a qualified herbalist for personalized dosing.

Is Helichrysum arenarium safe during pregnancy?

No, Helichrysum arenarium is considered unsafe during pregnancy. The herb stimulates bile flow and uterine contractions, which poses a risk of miscarriage or premature labor. Additionally, safety data regarding lactation is insufficient. Women who are pregnant or breastfeeding should avoid this herb entirely. This contraindication is based on traditional knowledge and pharmacological reasoning regarding emmenagogue effects (Evidence Level D).

What are the side effects of Helichrysum arenarium?

Common side effects of Helichrysum arenarium are generally mild but may include gastrointestinal upset, such as nausea or stomach cramping, particularly if taken on an empty stomach. Because it belongs to the Asteraceae family, individuals with sensitivities to plants like ragweed may experience allergic reactions. It is contraindicated for those with bile duct obstruction. These safety concerns are based on traditional use and theoretical extrapolation (Evidence Level C).

Résumé

Helichrysum arenarium, also known as sandy everlasting, is a perennial herb native to Europe, Central Asia, and China with recognized antioxidant and antimicrobial properties [PMID:30131818, PMID:35209096].

Contexte

Helichrysum arenarium (L.) Moench is a herbaceous perennial plant of the Asteraceae family [PMID:30131818]. It occurs in sand grasslands and is considered declining or endangered in several parts of its European range [PMID:38371858].

Usages traditionnels

The flowers have a long tradition in European ethnomedicine as a cholagogue, choleretic, hepatoprotective, and detoxifying herbal drug [PMID:30131818, PMID:11090997]. In Romanian traditional medicine, it is also known for diuretic and anti-inflammatory properties [PMID:29438342].

Composés actifs

The plant is rich in phenolic compounds, particularly flavonoids (such as naringenin, apigenin, and luteolin-7-O-glucoside), chalcones, phenolic acids (including chlorogenic acid), coumarins, and pyrones [PMID:30131818, PMID:35209096, PMID:24931335]. Essential oils contain constituents such as alpha-pinene, sabinene, palmitic acid, and trans-beta-caryophyllene [PMID:35209096, PMID:35406931]. Other isolated compounds include sterols, lignans, and prenylated phthalide glycosides [PMID:30131818, PMID:19431016].

Mécanisme d'action

The herb exhibits antioxidant activity via hydrogen-donating ability and reducing power [PMID:10892893, PMID:11090997]. Certain flavonoids may inhibit tumor necrosis factor-alpha (TNF-alpha) induced cytotoxicity [PMID:19336929] and inhibit dipeptidyl peptidase-IV (DPP-IV) [PMID:25921859]. It may also modulate inflammatory status and the composition of human gut microbiota [PMID:37431025].

Preuves cliniques

Preuve BMetabolic Syndrome

Daily consumption of H. arenarium infusion for 28 days resulted in a greater reduction in serum glucose levels and improvement in the lipid profile compared to H. italicum [PMID:35749144].

Preuve DMyocardial Inflammation (Diabetic Rats)

Flavonoid extracts of H. arenarium were investigated for the alleviation of myocardial inflammation and protection of high-glucose damaged cardiomyocytes [PMID:35495751].

Preuve DBacterial Infections

Methanol extracts showed antibacterial activity against Staphylococcus aureus and Streptococcus pneumoniae [PMID:24931335].

Sécurité et effets indésirables

No direct adverse effects of the herb itself are listed; however, a case of occupational dermatitis was reported in workers packing the herb, which was attributed to the presence of the ectoparasite Pyemotes ventricosus rather than the plant itself [PMID:28445563].

Posologie et administration

In a clinical trial, 1 g of dried plant material in a tea filter bag was consumed daily for 4 weeks [PMID:37431025]. No PubMed data available. Consult a healthcare provider.

Synthèse des preuves

Evidence consists primarily of in vitro studies, animal models, and small-scale randomized comparative trials (n=13 to 14 per group), suggesting potential benefits for metabolic syndrome and antioxidant activity, but large-scale clinical validation is lacking.
