Gumpii (Pittosporum angustifolium)

→ Shop Gumpii Extract

Traditional Use

• Broad-spectrum Aboriginal bush medicine — used across multiple body systems
• High in saponins, alkaloids, tannins, flavonoids
• Naturally antimicrobial, antibiotic, antiviral, anti-inflammatory, antifungal, antiparasitic
• Immune booster, anti-allergy
• Traditional benefits: anticoagulant, antioxidant, anti-cancer, anti-diabetic, analgesic, anti-inflammatory, anti-neurodegenerative, immune boosting
• Used historically for arthritis, chronic fatigue syndrome (CFS), autoimmune disorders, emphysema, chest infections, rheumatic complaints, sciatica, skin diseases

Naturally Occurring Compounds

• Saponins — hepatoprotective, adaptogenic, expectorant, diuretic, cholesterol-lowering, antioxidant
• Alkaloids — pharmacologically active nitrogen-containing compounds unique to the Pittosporaceae family
• Tannins — antimicrobial via inhibition of bacterial enzymes and membrane disruption
• Flavonoids — antioxidant, anti-inflammatory, antiviral; described as "nature's biological response modifiers"
• Phenolic acids (chlorogenic, caffeic, ferulic) — antioxidant and anti-inflammatory activity
• Triterpenoid saponins — DNA topoisomerase I inhibition confirmed (Bäcker et al., 2016)
• Phytoestrogens — hormonal modulation, bone health

Laboratory Research Context

In preliminary laboratory studies, Pittosporum angustifolium was identified as the most cytotoxic of all Australian native plant extracts tested against HeLa (cervical cancer) and HT29 (colorectal cancer) cell lines. Extracts demonstrated strong inhibitory activity against Klebsiella pneumoniae and Proteus mirabilis, and inhibited Ross River virus-induced cytopathicity by more than 25%.

Candida albicans: P. angustifolium leaf and stem extracts have demonstrated strong antifungal activity against Candida albicans — one of the most clinically significant fungal pathogens and a primary reason many customers seek out Gumpii. This activity is supported by the broad antifungal compound profile including saponins, tannins, and flavonoids (Phan et al., 2020).

Early-stage laboratory research only. Not clinical evidence of efficacy in humans.

Wilga (Geijera parviflora)

→ Shop Wilga Extract

Traditional Use

• One of Australia's most versatile native botanicals — used across multiple applications in traditional Aboriginal bush medicine
• Leaves used to numb pain, particularly toothache — applied both internally and externally
• Traditional use for immune support, anti-inflammatory, antimicrobial, antiviral, antifungal, and antiparasitic applications
• Topically: insect bites (including venomous and necrosing bites), natural insect repellent, antifungal skin conditions

Naturally Occurring Compounds

• Coumarins — the dominant compound class; high bioavailability, broad-spectrum activity, low toxicity. Alcohol extraction captures coumarins completely absent from steam-distilled essential oils (Sadgrove et al., 2016)
• Geiparvarin — a naturally occurring compound unique to Geijera parviflora; demonstrated antiproliferative activity against multiple tumour cell lines via anti-microtubular mechanism (inhibits tubulin polymerization; acts in a vinblastine-like fashion)
• Anthranilic acid derivatives — five isolated from ethanol leaf extract (Shou et al., Fitoterapia 2014); mixture I and compound 5 (hexadecanoylanthranilic acid) showed good antibacterial activity against multiple Gram-positive strains including MRSA (S. aureus ATCC 43300)
• Linalool, geijerene/pregeijerene, 1,8-cineol, bicyclogermacrene — major essential oil components; demonstrated highest antimicrobial and free radical scavenging activity among Australian native plants tested
• Monoterpenoids, sesquiterpenoids, and diterpenes — confirmed by HPLC profiling of alcohol extracts
• D-limonene — subject of ongoing chemopreventive research
• Parviflorane A and B — two unusual 11-carbon alkaloids isolated from leaves (Shou et al., J Nat Prod 2013)

Laboratory Research Context

Research has confirmed antimicrobial activity against Gram-positive bacterial strains and antifungal activity against T. interdigitalis, T. rubrum, and T. mentagrophytes. The essential oil components — particularly linalool, geijerene/pregeijerene, 1,8-cineol, and bicyclogermacrene — demonstrated the highest antimicrobial and free radical scavenging activity of all Australian native plants tested in the study.

Geiparvarin — a natural compound isolated from G. parviflora leaves — inhibits the growth of various tumour cell lines via anti-microtubular activity. It inhibits tubulin polymerization and deranges the microtubular network, acting in a vinblastine-like fashion. Studies have explored its activity in combination with taxol (paclitaxel), with conjugated derivatives showing stronger cytoskeletal disruption than either compound alone (Miglietta et al., 1997; Bocca et al., 2001).

Coumarin compounds from the Rutaceae family are being actively studied across neurological, cardiovascular, antidiabetic, and cellular health applications. In vitro cytotoxicity of crude polar extracts of Australian native plants including Geijera parviflora has been evaluated (Mani et al., 2022, SAGE Journals).

Early-stage laboratory research only. Not clinical evidence of efficacy in humans.

Australian Mistletoe (Loranthaceae family)

→ Shop Australian Mistletoe Extract | → Shop Mistletoe Capsules

Australian Species

True Australian mistletoes belong primarily to the family Loranthaceae. Key species include:

• Amyema miquelii (Box Mistletoe) — essential oil rich in terpenes regardless of Eucalyptus host species
• Amyema quandang (Grey-leaf Mistletoe)
• Dendrophthoe vitellina (Long-flowered Mistletoe)
• Dendrophthoe falcata (Banda/Bandaka) — native to India, Sri Lanka, Thailand, Indo-China, and Australia; extensively documented in Ayurvedic medicine
• Muellerina eucalyptoides (Creeping Mistletoe)
• Loranthus longiflorus — used in Ayurvedic medicine for inflammatory conditions, ulcers, wounds, and systemic disorders
• Tapinanthus globiferus — antimicrobial activity confirmed against bacteria and fungi

Mistletoe is a hemiparasitic plant — it attaches to host trees via specialised structures called haustoria, extracting water and minerals from the host's xylem and phloem while still performing some photosynthesis independently. Notably, the medicinal properties of mistletoe may vary depending on the host plant species, as the parasite absorbs minerals and compounds directly from its host.

Traditional & Medicinal Use

• Name believed to derive from the Celtic word for "all-heal" — one of the longest recorded histories of any medicinal plant
• Anti-inflammatory & wound healing — leaf paste applied topically to wounds; fresh leaf juice used for swelling and pain relief; ethanolic extract demonstrated accelerated wound contraction and enhanced tensile strength in scientific studies
• Antimicrobial — alkaloids, flavonoids, phenols, tannins, and saponins contribute to activity against bacteria and fungi
• Cardiovascular — antihypertensive, antiarrhythmic, strengthens the heart, regulates blood pressure, supports circulation; normalises circulation and reduces palpitations and anxiety during menopause; controls bleeding disorders and oedema. Research on Loranthus ferrugineus (Macquarie University, 2015) confirmed remarkable BP-lowering activity via muscarinic receptor stimulation
• Nervous system — nervine tonic for epilepsy, hysteria, convulsions, psychiatric disorders; neuroprotective terpenes (pinene, linalool) researched for Alzheimer's and Parkinson's
• Anticancer & immunomodulation — improves cytokine release, protects DNA, reduces chemotherapy side effects; cytotoxic activity against MCF-7 breast cancer (IC₅₀ 10.65 µg/mL), Ehrlich ascitic carcinoma, skin cancer, chronic myeloid leukaemia, and myeloma cell lines. Rudolf Steiner introduced mistletoe into oncology in 1920; one of the most widely used complementary cancer therapies in Europe today
• Digestive — diarrhoea, dysentery, dyspepsia, anti-ulcer, gastrointestinal wellness
• Respiratory — cough, bronchial asthma, bronchitis, colds, fever
• Reproductive — Garbhasthapaka — supports fetal retention and sustains pregnancy (Ayurvedic tradition); menstrual support
• Urinary — kidney stones, dysuria, urinary retention (leaf juice 10–15 ml)
• Metabolic & nutritional — leaves contain iron, calcium, potassium, manganese, and magnesium; dietary fibre aids cholesterol management; supports blood sugar regulation, hypertension, and arthritis
• Gerontological — memory enhancement and well-being in the elderly

Naturally Occurring Compounds

• Lectins & Viscotoxins — glycoproteins and polypeptides with immunomodulatory, cytotoxic, and apoptosis-inducing properties; primary focus of modern mistletoe cancer research
• Flavonoids — quercetin, quercitrin, 4"-O-acetylquercitrin, kaempferol, rutin; anticancer, anti-inflammatory, antioxidant, antiproliferative
• Tannins & Loranthin — gallic acid, ellagic acid, chebulinic acid; antiviral, antibacterial, anticancer; loranthin is a newly identified flavanocoumarin with free radical scavenging activity
• Alkaloids — vasodilatory, anti-asthmatic, antimicrobial
• Terpenes — myrcene, alpha-pinene, beta-caryophyllene, limonene, linalool, humulene (see Terpene section below)
• Sterols — β-sitosterol, stigmasterol, β-amyrin, oleanolic acid
• Gallic Acid — neuroprotective activity
• Beta-phenylethylamine & Tyramine — activity in degenerative joint conditions
• Polysaccharides — immune system modulation, antiviral, proapoptotic effects
• Minerals — iron, calcium, potassium, manganese, magnesium

The Role of Terpenes in Australian Mistletoe

Terpenes are a major bioactive compound class in Australian Loranthaceae mistletoes. The essential oil of Amyema miquelii is rich in terpenes regardless of which Eucalyptus host species it grows on — demonstrating host-independent terpene production. Research has documented the following terpene activities:

• Anti-inflammatory & analgesic — myrcene, alpha-pinene, and beta-caryophyllene block key inflammatory signalling pathways; beta-caryophyllene and myrcene activate cannabinoid receptors. A University of Arizona study found certain terpenes as effective as morphine for neuropathic pain
• Antioxidant & anticancer — limonene, alpha-pinene, and myrcene function as powerful antioxidants; limonene, beta-caryophyllene, and humulene have shown anticancer properties in preclinical studies by inhibiting tumour cell growth, inducing apoptosis, and interfering with cancer cell signalling pathways
• Antimicrobial & antiviral — limonene, carvacrol, and thymol disrupt bacterial and fungal cell membranes; terpenes can enhance the effectiveness of existing antibiotics; antiviral properties researched including against West Nile virus
• Neuroprotective & mood-regulating — pinene and linalool protect nerve cells from damage (researched for Alzheimer's and Parkinson's); myrcene and linalool have sedative and calming properties supporting anxiety, stress, and sleep; limonene has uplifting, mood-enhancing effects; pinene may benefit memory and cognitive function
• Entourage effect — terpenes work synergistically with other plant compounds to modulate and enhance overall therapeutic activity

Laboratory Research Context

Mistletoe is one of the most extensively researched complementary herbs in oncology. Lectins (ML-I, ML-II, ML-III) function as ribosome-inactivating proteins that inhibit protein biosynthesis in cancer cells, inducing apoptosis and necrosis. Viscotoxins further contribute cytotoxic and immunogenic effects.

In vitro studies of Dendrophthoe falcata demonstrated cytotoxic activity against breast cancer (MCF-7, IC₅₀ 10.65 µg/mL), Ehrlich ascitic carcinoma, skin cancer, chronic myeloid leukaemia, and myeloma cell lines. The anticancer effect is associated with upregulation of pro-apoptotic markers p53 and BAX and downregulation of anti-apoptotic gene BCL-2.

For cardiovascular activity, research on Loranthus ferrugineus (Macquarie University / Journal of Pharmacopuncture, 2015) confirmed remarkable BP-lowering activity — the lipid fraction methanol extract (LFME) was most potent, acting via muscarinic receptor stimulation to modulate norepinephrine-induced aortic ring contraction. Rudolf Steiner first introduced mistletoe into oncology in 1920; it remains one of the most widely used complementary cancer therapies in Europe today.
