The Short Answer
Umhlabazane leaves contain high concentrations of 3,4,5-tri-O-galloylquinic acid (up to 50% of hydrated leaf dry mass), gallic acid (26.62% of extract), and trehalose (34.7 ± 7.2 mg/g), which together confer antioxidant, antimicrobial, and membrane-stabilizing activities through polyphenolic free-radical scavenging and protein/lipid protection. Preclinical in vitro evidence demonstrates inhibition of HIV-1 and M-MLV reverse transcriptase by polyphenolic fractions and antimicrobial activity against a range of pathogens via terpenoid membrane disruption, but no human clinical trials have been completed to quantify effect sizes in gastrointestinal or other conditions.

Health Benefits
**Antioxidant Protection**: Gallic acid (26
62% of extract) and 3,4,5-tri-O-galloylquinic acid scavenge reactive oxygen species and prevent lipid peroxidation, reducing cellular oxidative damage measured in DPPH and ABTS in vitro assays.
**Antimicrobial Activity**: Essential oil constituents trans-pinocarveol (19
57%) and pinocarvone (11.13%), alongside carvacrol, disrupt bacterial and fungal cell membranes, demonstrating broad-spectrum antimicrobial action in laboratory minimum inhibitory concentration studies.
**Antiviral Properties**
Polyphenolic fractions including gallic acid and 3,4,5-tri-O-galloylquinic acid inhibit retroviral reverse transcriptase activity (HIV-1 and M-MLV) in ethidium bromide fluorescence assays, suggesting potential as an antiviral adjunct pending clinical validation.
**Anti-inflammatory Effects**: Ferulic acid (15
23% of extract) and arbutin modulate redox-sensitive inflammatory pathways, reducing pro-inflammatory signaling in vitro; arbutin additionally restores cell viability under oxidative stress conditions.
**Gastrointestinal Support**
Traditional Zulu use as a caffeine-free herbal tea for stomach ailments is supported by the plant's polyphenolic tannins, which may reduce intestinal permeability and exert astringent and antimicrobial actions on gastrointestinal mucosa.
**Skin and Membrane Protection**: Trehalose (34
7 ± 7.2 mg/g) stabilizes proteins and lipid bilayers against desiccation and environmental oxidative stress, while arbutin inhibits melanogenesis—making leaf extracts of interest in topical cosmeceutical formulations.
**Antidiabetic Potential**
Quercetin glucoside (3 mg/g aqueous extract) and ellagic acid exhibit alpha-glucosidase inhibitory and insulin-sensitizing properties in cell-based models, consistent with traditional use for diabetes management in southern African ethnomedicine.
Origin & History
Natural habitat
Myrothamnus flabellifolius is a desiccation-tolerant resurrection plant native to rocky outcrops and cliff faces across southern and central Africa, including South Africa, Zimbabwe, Namibia, and Mozambique. It thrives in xeric, drought-prone environments and is one of only two known angiosperm species in the family Myrothamnaceae, uniquely capable of surviving almost complete dehydration and reviving upon rehydration. The plant is not commercially cultivated at scale; wild harvesting from rocky hillside habitats is the primary source for traditional and experimental use.
“Myrothamnus flabellifolius has been integrated into the traditional medicine of Zulu, Sotho, Venda, and other southern and central African peoples for centuries, where it is valued under the name Umhlabazane (Zulu) and related vernacular terms for treating a broad spectrum of conditions including epilepsy, mental disorders, cough, pain, stroke, shingles, hypertension, kidney ailments, asthma, and gastrointestinal complaints. The plant's remarkable ability to desiccate completely and resurrect upon rehydration has earned it deep cultural respect as a symbol of resilience and renewal in the regions where it grows. Preparation in traditional practice centers on simple aqueous decoctions or infusions of the leaves consumed as a medicinal tea, sometimes combined with other locally sourced plants in polyherbal formulations. More recently, ethnobotanical surveys have documented its use across at least seven southern African countries, confirming consistent cross-cultural application for respiratory and gastrointestinal ailments and stimulating modern phytochemical interest in its bioactive constituents.”Traditional Medicine
Scientific Research
The available evidence for Myrothamnus flabellifolius is entirely preclinical, consisting of in vitro biochemical assays, crude extract characterization studies, and a limited number of animal feeding trials; no peer-reviewed human clinical trials with quantified sample sizes, randomization, or defined effect sizes have been published as of the available literature. Antioxidant activity has been quantified by DPPH, ABTS, and FRAP assays across multiple independent laboratories, consistently showing high radical-scavenging capacity correlating with total polyphenol content. Antiviral data derive from a small number of enzyme inhibition assays demonstrating IC50-level inhibition of M-MLV and HIV-1 reverse transcriptase by polyphenolic fractions, but these have not been replicated in cell culture infection models or animal systems. Phytochemical characterization studies are robust and reproducible, but genotoxicity, pharmacokinetics, bioavailability in humans, and therapeutic dose-response relationships remain entirely unstudied, representing critical gaps before any clinical application can be substantiated.
Preparation & Dosage
Traditional preparation
**Traditional Herbal Tea**
5–10 g dry leaf) per cup
Dried or fresh leaves are steeped in boiling water to produce a caffeine-free infusion; no standardized leaf weight or steeping time is defined in the ethnobotanical literature, though typical southern African practice uses a small handful (~.
**Aqueous Extract (Laboratory Standard)**
3 mg/g extract; no standardization for human supplement use has been established
Aqueous extracts used in research studies are prepared at concentrations yielding quercetin glucoside at approximately .
**Essential Oil (Hydro-distillation)**
Volatile fraction containing trans-pinocarveol (19.57%) and pinocarvone (11.13%) is obtained by hydro-distillation of dried leaves; used in antimicrobial research but not formulated for oral supplementation.
**Topical Cosmeceutical Extract**
Aqueous leaf extracts enriched in trehalose and arbutin are incorporated into skin-care products at undisclosed concentrations for anti-aging and skin-brightening purposes; no clinical dose-response data are available.
**No Established Therapeutic Dose**
Because no human pharmacokinetic or clinical efficacy studies exist, no evidence-based oral supplemental dose, standardization percentage, or dosing interval can be recommended at this time.
Nutritional Profile
Myrothamnus flabellifolius leaves are phytochemically dense rather than macronutrient-rich. The primary nutritional and bioactive constituents per dry weight include: 3,4,5-tri-O-galloylquinic acid (up to 50% of hydrated leaf dry mass; 33% of desiccated leaves), gallic acid (26.62% of extract), ferulic acid (15.23% of extract), trehalose (34.7 ± 7.2 mg/g), sucrose (56.5 ± 6.6 mg/g), raffinose (2.49 g/100 g), stachyose (2.18 g/100 g), gallocatechin (1.43 ± 0.03 mg/g), quercetin glucoside (3 mg/g aqueous extract), and arbutin (present, unquantified). The essential oil fraction contains trans-pinocarveol (19.57%), pinocarvone (11.13%), and carvacrol. Oligosaccharides raffinose and stachyose serve as osmotic protectants in the plant and may confer prebiotic effects in the gut, though this has not been investigated in human digestion studies. Bioavailability of polyphenols from leaf tea is expected to be moderate, subject to gut microbiome metabolism of gallotannins into smaller phenolic acids, but no human pharmacokinetic data exist.
How It Works
Mechanism of Action
The dominant polyphenol 3,4,5-tri-O-galloylquinic acid, along with gallic acid and ellagic acid, acts as a potent electron donor to neutralize reactive oxygen species and chelates metal ions to prevent Fenton-type oxidative reactions, while simultaneously intercalating into or binding the active sites of viral reverse transcriptases (HIV-1 and M-MLV) as demonstrated in ethidium bromide fluorescence competition assays. Terpenoid volatiles trans-pinocarveol and pinocarvone insert into microbial phospholipid bilayers, increasing membrane permeability and causing leakage of intracellular contents, resulting in bacteriostatic or bactericidal outcomes depending on concentration. Trehalose forms hydrogen bonds with membrane phospholipid head groups and stabilizes protein tertiary structure during desiccation or oxidative stress, protecting cellular integrity—a mechanism hypothesized to extend to smoke- and pollution-challenged skin cells. Arbutin competitively inhibits tyrosinase to suppress melanin synthesis and independently reduces lipid peroxidation chain reactions, while ferulic acid upregulates endogenous antioxidant enzymes through Nrf2 pathway activation in preclinical cell models.
Clinical Evidence
No human clinical trials have been conducted on Myrothamnus flabellifolius for any indication, including its primary traditional use in treating stomach ailments. All reported biological activities—antioxidant, antiviral, antimicrobial, anti-inflammatory, antidiabetic, and anticancer—are derived from in vitro experiments using crude aqueous or ethanol extracts, essential oil fractions, or isolated compounds tested in cell-free enzyme assays. No outcomes such as symptom resolution, biomarker changes, or adverse event rates have been measured in human subjects, and no effect sizes, confidence intervals, or number-needed-to-treat figures are available. Confidence in translating preclinical findings to clinical benefit is therefore very low, and the ingredient should be regarded as a candidate for future human research rather than an evidence-based therapeutic agent.
Safety & Interactions
Formal toxicological evaluation of Myrothamnus flabellifolius is very limited: no genotoxicity studies, no acute or chronic oral toxicity studies in recognized animal models, and no human adverse event data have been published, leaving the safety profile largely uncharacterized beyond centuries of traditional use without widely reported harm. Drug interactions have not been investigated; given the high polyphenol content and the known capacity of gallic acid and tannins to chelate metal ions and inhibit cytochrome P450 enzymes in other botanical contexts, caution is theoretically warranted with co-administration of iron supplements or drugs with narrow therapeutic indices metabolized by CYP1A2 or CYP3A4. No contraindications have been formally established, and traditional use does not document specific restrictions; however, pregnant and lactating women should avoid therapeutic doses due to the complete absence of reproductive toxicity data. Maximum safe doses have not been determined for any route of administration, and self-medication beyond traditional tea preparation should be approached with caution until human safety studies are conducted.

No human clinical trials have verified these traditional applications.
What are the main active compounds in Myrothamnus flabellifolius?
The dominant bioactive compound is 3,4,5-tri-O-galloylquinic acid, which can constitute up to 50% of the hydrated leaf dry mass and 33% of desiccated leaves. Other major compounds include gallic acid (26.62% of extract), ferulic acid (15.23%), trehalose (34.7 ± 7.2 mg/g), sucrose (56.5 ± 6.6 mg/g), raffinose (2.49 g/100 g), arbutin, gallocatechin (1.43 ± 0.03 mg/g), and quercetin glucoside (3 mg/g aqueous extract), alongside essential oil terpenoids trans-pinocarveol (19.57%) and pinocarvone (11.13%).
Is there scientific evidence that umhlabazane works?
Current evidence is limited entirely to in vitro laboratory studies and traditional use reports; no human clinical trials have been published. Preclinical research demonstrates antioxidant activity in DPPH and ABTS assays, inhibition of HIV-1 and M-MLV reverse transcriptase by polyphenolic fractions, and broad-spectrum antimicrobial activity from essential oil terpenoids. These findings are promising but cannot be directly extrapolated to human therapeutic outcomes without controlled clinical trials.
Is umhlabazane safe to drink as a tea?
Umhlabazane has been consumed as a herbal tea across southern Africa for centuries without widely reported adverse effects, suggesting reasonable tolerability at traditional preparation amounts. However, formal toxicology studies—including genotoxicity, chronic oral toxicity, and reproductive safety assessments—have not been conducted, and no maximum safe dose has been established. Individuals who are pregnant, breastfeeding, or taking medications metabolized by cytochrome P450 enzymes or who use iron supplements should exercise caution and consult a healthcare provider before regular use.
What does the resurrection plant (umhlabazane) do for skin?
Myrothamnus flabellifolius extracts are explored in cosmeceutical formulations primarily for their trehalose content (34.7 ± 7.2 mg/g), which stabilizes skin lipids and proteins against oxidative and desiccation stress, and arbutin, which inhibits the enzyme tyrosinase to reduce melanin synthesis and brighten skin tone. Gallic acid and ferulic acid in the extract additionally provide antioxidant protection against UV- and pollution-induced skin aging. These activities are supported by in vitro and topical bioavailability data, but no published randomized controlled trials in human subjects have quantified skin improvement outcomes.
Does umhlabazane interact with antibiotics or antifungal medications?
Umhlabazane contains antimicrobial compounds like trans-pinocarveol and pinocarvone that may have additive or competing effects with prescription antibiotics and antifungals. While traditional use suggests potential synergy, concurrent use with clinical antimicrobials should be discussed with a healthcare provider to avoid unexpected interactions or reduced medication efficacy. Limited clinical data exists on specific drug interactions, making professional guidance essential before combining umhlabazane with prescribed antimicrobial treatments.
Is umhlabazane safe for pregnant or nursing women?
There is insufficient clinical research on umhlabazane's safety during pregnancy and lactation, and it is not recommended for use in these populations without medical supervision. The herb's active compounds, including gallic acid and essential oils, have not been evaluated for potential effects on fetal development or infant safety through breast milk. Pregnant and nursing women should consult a healthcare provider before using umhlabazane or products containing it.
What is the difference between umhlabazane tea and umhlabazane extract supplements?
Umhlabazane tea provides a traditional, water-based infusion that extracts water-soluble compounds but may deliver lower concentrations of lipophilic essential oils like pinocarveol. Concentrated extracts or supplements typically standardize active compounds (such as gallic acid) and may offer higher bioavailability and more consistent dosing than brewed tea. Extract supplements may also preserve volatile essential oils more effectively than heat-based tea preparation, potentially offering stronger antimicrobial and antioxidant effects per serving.
