Mulungu (Erythrina mulungu): Benefits, Dosage, Safety & Evidence

Questions fréquentes

How does Mulungu work for anxiety and sleep?

Mulungu contains alkaloids including erysothrine, erysovine, hypaphorine, and erythraline that act on the central nervous system. These compounds appear to modulate GABA receptors and other neurotransmitter systems, producing sedative and anxiolytic effects. The bark's active constituents help calm nervous activity and promote relaxation without the addictive potential associated with pharmaceutical sedatives. Evidence level: C (preliminary clinical evidence and traditional use).

Can I take Mulungu with other medications or antidepressants?

Mulungu should not be combined with CNS depressants including benzodiazepines, barbiturates, alcohol, sleep medications, or certain antidepressants, as this can cause excessive sedation and respiratory depression. Due to its potential blood pressure-lowering effects, it may also interact with antihypertensive medications. Always consult a qualified healthcare provider before combining Mulungu with any prescription medications. Evidence level: C.

What is the recommended dosage for Mulungu bark tincture?

For adults, the typical dosage is 1-3ml of bark tincture taken 2-3 times daily, or approximately 500mg of standardized extract at bedtime for insomnia. Traditional preparations use decoctions of the bark. Start with the lowest effective dose and adjust based on individual response. Do not exceed recommended amounts without professional guidance. Evidence level: C (traditional use and preliminary evidence).

Is Mulungu safe during pregnancy and breastfeeding?

Mulungu is contraindicated during pregnancy and breastfeeding. The herb's sedative alkaloids may cross the placenta or pass into breast milk, potentially affecting fetal and infant development. There is insufficient safety data for use during these periods. Women who are pregnant, nursing, or planning pregnancy should avoid Mulungu entirely and consult their healthcare provider for alternative options. Evidence level: C.

What is Mulungu used for in traditional Brazilian medicine?

Mulungu has been used for centuries by Indigenous peoples of Brazil and in South American folk medicine primarily for anxiety, insomnia, and nervous disorders. Traditional applications include treating heart palpitations, calming nervous agitation, and serving as a general sedative. The bark is the primary plant part used, prepared as teas, tinctures, or extracts. It remains widely used in Brazilian phytotherapy today. Evidence level: C (traditional use).

What are the side effects of taking Mulungu?

Common side effects include strong sedation, drowsiness, and lowered blood pressure (hypotension). These effects are typically dose-dependent and may impair your ability to drive or operate machinery. Avoid activities requiring mental alertness until you know how Mulungu affects you. Discontinue use if you experience excessive drowsiness, dizziness, or difficulty breathing, and seek medical attention if symptoms persist. Evidence level: C.

Résumé

Mulungu (Erythrina mulungu) is a Brazilian native plant of the Fabaceae family used for its effects on the central nervous system [PMID:15025865, PMID:17070003].

Contexte

Erythrina mulungu is a medicinal plant native to Brazil [PMID:19441926, PMID:30102994].

Usages traditionnels

It is popularly used in Brazil for effects on the central nervous system [PMID:15025865, PMID:17070003] and for the treatment of respiratory diseases [PMID:30102994].

Composés actifs

Isolated alkaloids from the flowers include (+)-erythravine, (+)-11alpha-hydroxyerythravine, and (+)-alpha-hydroxyerysotrine [PMID:17253849]. Other isolated compounds include erysothrine [PMID:22381390].

Mécanisme d'action

Alkaloids (+)-erythravine and (+)-11alpha-hydroxyerythravine act as potent inhibitors of neuronal nicotinic receptor currents in mammalian cells [PMID:24349349]. These alkaloids do not appear to modulate main sodium and potassium channel isoforms, nor do they inhibit glutamate binding, GABA uptake, or increase glutamate uptake or GABA binding in rat cortical synaptosomes [PMID:32735983].

Preuves cliniques

Preuve BDental Anxiety

In a triple-blind RCT, 500 mg of E. mulungu was unable to control anxiety in patients undergoing third molar extraction, performing differently than Passiflora incarnata and midazolam [PMID:32951121]. In a separate double-blind crossover study, patients showed a higher preference for E. mulungu over placebo, though no statistically significant differences were verified in blood pressure, heart rate, or oxygen saturation [PMID:24880443].

Preuve DAnxiety (Animal Models)

Aqueous alcoholic crude extracts and purified alkaloids demonstrated anxiolytic-like effects in mice and rats using elevated T-maze and light-dark transition models [PMID:11960198, PMID:14600397, PMID:17253849, PMID:17268084].

Preuve DSeizures (Animal Models)

Alkaloids (+)-erythravine and (+)-11alpha-hydroxyerythravine inhibited seizures evoked by bicuculline, pentylenetetrazole, and kainic acid in rats [PMID:21277832]. Erysothrine also inhibited seizures evoked by bicuculline, PTZ, NMDA, and kainic acid [PMID:22381390].

Preuve DAsthma (Animal Model)

Ethanolic extract from flowers attenuated allergic airway inflammation and hyperresponsiveness in a murine model of asthma [PMID:30102994].

Preuve DPain (Animal Model)

Interactions médicamenteuses

In vitro studies using HepG2 and Caco-2 cells showed that non-toxic concentrations (100 μg/mL) of plant infusions did not affect P-glycoprotein (P-gp) activity [PMID:27594838].

Synthèse des preuves

Evidence is primarily based on animal models (D) and limited clinical trials (B). While animal studies suggest anxiolytic and anticonvulsant properties, clinical evidence for anxiety control in dental settings is inconsistent or negative.
