Himatanthus sucuuba contains bioactive compounds including uleine, guanidine alkaloids, iridoids, and triterpenes that contribute to its therapeutic effects. Research suggests these compounds exhibit anti-inflammatory, analgesic, and potential antiparasitic properties. The uleine and related alkaloids may modulate inflammatory pathways, while triterpenes contribute to wound-healing and potential anticancer activity. However, mechanisms are not fully understood and require further study (Evidence level: C).
Does Himatanthus sucuuba interact with medications?
Limited research exists on specific drug interactions with Himatanthus sucuuba. Due to documented cardiac effects, caution is advised when combining this herb with cardiac medications, including antiarrhythmics, antihypertensives, and digoxin. The latex may also affect gastrointestinal function, potentially altering absorption of oral medications. Individuals taking prescription drugs should consult a healthcare provider before use. No formal interaction studies have been conducted (Evidence level: D).
What is the recommended dosage for Himatanthus sucuuba?
Traditional adult dosages include 5-10ml of latex diluted in water, or approximately 200mg of standardized extract daily. Dosage varies depending on the specific preparation and intended use. Due to potential toxicity at higher doses, users should not exceed recommended amounts. Insufficient clinical evidence exists to establish optimal therapeutic dosing. Consult a qualified healthcare practitioner for personalized guidance (Evidence level: C/Traditional).
Is Himatanthus sucuuba safe during pregnancy?
Himatanthus sucuuba is considered unsafe during pregnancy and should be strictly avoided. The latex contains compounds that may stimulate uterine contractions or cause fetal harm. Traditional use has excluded pregnant women, and no safety data exists for breastfeeding mothers. Women who are pregnant, planning pregnancy, or breastfeeding should not use this herb. This contraindication is supported by traditional knowledge and theoretical safety concerns (Evidence level: D/Traditional).
What is Himatanthus sucuuba used for traditionally?
Indigenous Amazonian tribes have traditionally used Himatanthus sucuuba latex for treating intestinal parasites, pain, and ulcers. Additional traditional applications include wound healing, inflammation, and cancer support. The bark and latex are the primary plant parts utilized medicinally. While these uses are well-documented in ethnobotanical literature, clinical evidence supporting efficacy remains limited and further research is needed (Evidence level: C/Traditional).
What side effects can Himatanthus sucuuba cause?
Reported side effects include nausea and vomiting, particularly at higher doses. The latex may cause cardiac effects, making it unsuitable for individuals with pre-existing heart conditions. Excessive consumption can lead to severe gastrointestinal distress. Children should not use this herb due to toxicity concerns. Use should be limited to recommended dosages under professional guidance. Long-term safety data is lacking (Evidence level: C/D).

Résumé
Himatanthus sucuuba is an Amazonian tree used in traditional medicine for its anti-inflammatory, wound-healing, and leishmanicidal properties [PMID:11724243, 34686006, 17459622].
Contexte
Himatanthus sucuuba, also known as "Bellaco caspi", is a medicinal plant from the Apocynaceae family found in the Amazon [PMID:34686006, 11724243].
Usages traditionnels
In Peruvian traditional medicine, the latex is used to treat wounds, inflammation, ulcers, and cutaneous leishmaniasis (Uta) [PMID:32801553, 17459622]. It is also used in the treatment of gastritis and haemorrhoids [PMID:1795523].
Composés actifs
The plant contains spirolactone iridoids such as plumericin and isoplumericin [PMID:11724243, 17459622], and pentacyclic triterpenes including lupeol acetate, lupeol cinnamate, lupeol beta-phenyl propionate, and alpha-amyrin cinnamate [PMID:11724243]. Other identified components include phenolic acids, beta-dihydro-plumbericinic acid, plumeridoid C, and fulvoplumierin [PMID:34686006, 21979978, 690844]. Bark also contains confluentic acid and 2'-O-methylperlatolic acid [PMID:8069971].
Mécanisme d'action
Plumericin acts as a potent inhibitor of the NF-κB pathway [PMID:24329519]. In intestinal models, it reduces the expression of inflammatory factors such as tumor necrosis factor-α (TNF-α), cyclooxygenase-2, and inducible nitric oxide synthase [PMID:31914614]. The latex has been shown to increase nitric oxide (NO) and TNF-α while decreasing Transforming Growth Factor-beta (TGF-beta) production in macrophages [PMID:20096374].
Preuves cliniques
Preuve DCutaneous Leishmaniasis
Latex exhibited potent leishmanicidal activity against Leishmania amazonensis in vitro and reduced parasite load in vivo via oral administration [PMID:20096374]; plumericin showed reduction of macrophage infection similar to Amphotericin B [PMID:17459622].
Preuve DInflammation
Hexane fractions of latex inhibited carrageenan-induced rat paw edema by 35.9% at 200 mg/kg [PMID:10821061]; plumericin reduced intestinal inflammation and oxidative stress in DNBS-induced colitis models [PMID:31914614, 33445622].
Preuve DWound Healing
Latex is used traditionally for wounds [PMID:32801553], though one comparative study did not detect significant wound-healing activity for H. sucuuba compared to other plants [PMID:9080340].
Sécurité et effets indésirables
High doses (500 mg/kg) in rats caused significant decreases in maternal weight gain, fetal weight, and placental efficiency [PMID:26339763]. A dose of 250 mg/kg in rats caused increased preimplantation loss rate and reduced placental efficiency [PMID:26339763].
Grossesse et allaitement
A stem bark decoction (40 mg/rat twice daily) suggested low reproductive toxicity and teratogenic potential in rats [PMID:1795523], however, higher doses of H. sucuuba (250-500 mg/kg) significantly impaired maternal reproductive outcomes and fetal weight in rats [PMID:26339763].
Synthèse des preuves
The evidence is primarily based on in vitro studies and animal models (Level D), demonstrating significant anti-inflammatory and leishmanicidal activity, though high-dose toxicity in pregnant rats has been observed.
