Condiciones de salud que zanthoxylum puede ayudar a apoyar.
Antioxidant activity of Zanthoxylum extracts is robustly documented across multiple species and assay types. Studies consistently show potent DPPH radical scavenging, ferric reducing power, and superoxide scavenging. Key phytochemicals responsible include flavonoids, alkaloids, polyphenols, and terpenoids.
Preclinical evidence supports antihypertensive effects for certain Zanthoxylum species. Aqueous extract of Z. tessmannii (syn. Fagara tessmannii) attenuated L-NAME-induced hypertension in rats by lowering triacylglycerol, total cholesterol, and atherogenic index while protecting kidney, liver, and heart tissues. Human data are absent.
Multiple preclinical studies across several Zanthoxylum species demonstrate hypoglycemic activity. Extracts inhibit α-glucosidase and α-amylase enzymes, reduce fasting blood glucose in alloxan- and streptozotocin-induced diabetic rodents, and protect pancreatic β-cells. No human clinical trials have been conducted to date.
Antifungal activity of Zanthoxylum extracts against Candida species is documented in multiple laboratory studies. Z. zanthoxyloides extract showed significant activity against Candida albicans in in vitro assays. Several isolated coumarins and alkaloids from Zanthoxylum have documented antifungal mechanisms.
Multiple preclinical studies demonstrate cholesterol-lowering effects of Zanthoxylum extracts. Z. heitzii extract prevented elevation of hepatic LDL, VLDL, and total cholesterol in hypercholesterolemic rats; Z. armatum extracts significantly reduced serum cholesterol in diabetic mice; and Z. bungeanum fractions inhibited HMG-CoA reductase more effectively than simvastatin in cell studies.
Zanthoxylum species demonstrate robust anti-inflammatory activity in preclinical models, suppressing NF-κB, MAPK, and COX-2 pathways and reducing pro-inflammatory cytokines (TNF-α, IL-1β, IL-6). A 2024 mechanistic review confirmed these effects across multiple species, though human trials are lacking.
Antinociceptive and analgesic properties of Zanthoxylum are supported by multiple preclinical studies. Z. nitidum extract suppressed CFA-induced chronic inflammatory pain in mice via ERK1/2 and NF-κB signaling inhibition. The genus' use for chronic pain (rheumatism, arthralgia, injuries) is also extensively documented in TCM and global traditional medicine.
Antifungal activity of Zanthoxylum has been demonstrated in multiple laboratory studies against dermatophytes and Candida species. Z. caribaeum bark is traditionally used for fungal skin infections. Coumarins from Zanthoxylum have established antifungal properties. Evidence is largely in vitro.
Laboratory and animal evidence supports Zanthoxylum's antimicrobial and anti-inflammatory effects relevant to periodontal health. Z. zanthoxyloides is used as a chewing stick in West Africa, showing activity against periodontal pathogens. A 2025 animal study of Zanthoxyli Pericarpium (ZP) extract demonstrated protection against ligature-induced periodontitis in rats via combined antimicrobial, anti-inflammatory, and anti-resorptive mechanisms.
Cardiac protective effects of Zanthoxylum are demonstrated preclinically through anti-atherosclerotic, antihypertensive, and hypolipidemic actions in multiple animal models. Z. tessmannii extract protected heart tissue in hypertensive rat models; Z. heitzii extract prevented atherosclerotic plaque formation. No human cardiovascular outcome data exist.
Zanthoxylum's sanshool compounds directly interact with TRPV1 and TRPA1 sensory ion channels, providing a mechanistically documented neuroactive profile. Z. nitidum extract suppressed central sensitization in a chronic pain model via ERK/NF-κB pathways. Z. bungeanum isorhamnetin shows neuroprotective activity against neuroinflammation.
Anthelmintic activity of Zanthoxylum species is supported by in vitro and animal studies. Z. armatum seed extract showed efficacy against Haemonchus contortus in a ruminant model. Z. zanthoxyloides is a well-known traditional anthelmintic in Uganda and West Africa, and methanolic root-bark extract has demonstrated anthelmintic activity. Anti-trypanosomal and antimalarial activities of several species are also documented.
Rheumatoid arthritis-relevant preclinical evidence for Zanthoxylum includes suppression of NF-κB, ERK1/2, and pro-inflammatory cytokines in a CFA-induced chronic inflammatory joint pain model. Z. bungeanum polyphenols reduce inflammation via TLR4/MyD88/NF-κB and other pathways implicated in RA pathogenesis.
Zanthoxylum species—particularly Z. armatum—are known as 'toothache trees,' and their use for toothache relief is one of the most consistent and cross-culturally documented applications, with supporting antimicrobial and local anesthetic preclinical data. Z. armatum fruits demonstrated MIC activity against oral pathogens. The numbing (sanshoamide) compounds provide a local anesthetic mechanism.
Preclinical studies across multiple Zanthoxylum species demonstrate significant triglyceride-lowering effects. Z. armatum extracts reduced serum triglycerides in diabetic mice; Z. heitzii extract prevented aortic cholesterol and triglyceride elevation in hypercholesterolemic rats; hydroxy-α-sanshool from Z. bungeanum reduced serum TG in high-fat diet rats.
Gastroprotective and anti-ulcer effects of Zanthoxylum have been demonstrated in multiple animal models. Z. rhoifolium extract protected against ethanol-, HCl/ethanol-, indomethacin-, and stress-induced gastric lesions in mice/rats via mucus production, KATP channel activation, and nitric oxide mechanisms. Z. nitidum also showed gastric ulcer-protective effects.
Abdominal pain is one of the most consistently reported traditional uses of Zanthoxylum species across Asian, African, and Latin American traditions. The Chinese Pharmacopoeia lists abdominal pain among the primary indications of Z. bungeanum. Antispasmodic preclinical activity provides mechanistic support.
Rheumatism and arthralgia are among the most consistently documented traditional indications for Zanthoxylum species across Asia and Africa. Multiple species are used in TCM for rheumatic joint pain. Preclinical anti-inflammatory and analgesic evidence supports the mechanistic basis, but human arthritis trials are absent.
Asthma is listed as a traditional indication for Z. armatum in South Asian ethnobotany, and Z. caribaeum is traditionally used for asthma in the Caribbean. The antispasmodic and anti-inflammatory pharmacology of the genus provides indirect mechanistic support, but no clinical studies have been performed.
Zanthoxylum species have traditional use in Chinese medicine for improving blood circulation, described as 'warming meridians' and 'moving qi and blood.' This is supported by preliminary vasodilatory and antihypertensive effects in preclinical models, with no dedicated circulation clinical studies.
Zanthoxylum species have a long-documented tradition in Chinese, African, and South Asian medicine for treating diarrhea and intestinal disorders. The 2020 Chinese Pharmacopoeia lists Z. bungeanum, Z. schinifolium, and Z. nitidum in part for digestive complaints including diarrhea. Mechanistic antispasmodic and antimicrobial preclinical data support this use, but no dedicated human trials exist.
Multiple Zanthoxylum species have documented traditional uses as antipyretics across Africa, South Asia, and Latin America. Z. armatum is listed ethnobotanically for fever treatment in the Himalayas and South Asia, and Z. caribaeum is traditionally used for fever in the Caribbean. No controlled human clinical trials have been conducted.
Z. armatum has documented ethnobotanical use for headaches in South Asian traditional medicine. This use is part of a broader analgesic and anti-inflammatory folk medical tradition. No clinical or controlled preclinical studies specifically targeting headache have been conducted.
Zanthoxylum is listed in the Chinese Pharmacopoeia and multiple TCM traditions for use in vomiting and nausea. Traditional preparations are used across Asia for these complaints. Antispasmodic properties provide indirect mechanistic plausibility, but no clinical studies exist.
Zanthoxylum species have documented traditional use for sore throat and oral/throat infections across Africa and Asia. The antimicrobial, anti-inflammatory, and local anesthetic properties of the genus provide biological plausibility. No clinical studies specifically targeting sore throat have been conducted.
Treatment of urinary tract infections is one of the primary traditional indications for Zanthoxylum species documented in the Chinese Pharmacopoeia and African ethnobotanical records. Z. zanthoxyloides is used in Nigeria for urinary tract and venereal diseases. Antimicrobial properties provide mechanistic plausibility.
Traditional use of Zanthoxylum for wound healing is documented in South Africa, Kenya, Togo, and Nigeria. Pastes from Zanthoxylum species are applied to suppress wound pain and aid healing. Antimicrobial and antioxidant properties provide mechanistic plausibility. No controlled wound healing animal model studies specifically using Zanthoxylum have been indexed.
