Health properties
Angiangi (Usnea Lichens) has benefits that include:
Antimicrobial/antibacterial: contains usnic acid and other compounds with activity against some bacteria and fungi.
• Often used in salves, washes, or sprays aimed at minor skin infections, blemishes, and foot issues.
• Commonly combined with other antimicrobial plants (e.g. kawakawa, mānuka) for broader topical support.
Anti-inflammatory: traditional topical uses suggest soothing and reducing inflammation.
• Can be incorporated into balms for red, irritated, or chafed skin areas.
• Gentle preparations are sometimes used around, but not directly in, sensitive areas such as around wounds or rashes.
Wound-healing: used historically as a dressing to help prevent infection and support tissue repair.
• Dried strands have been placed directly on clean, minor cuts or scrapes as an improvised field dressing.
• Modern herbal practice often infuses angiangi into carrier oils to use in healing salves for minor wounds.
Respiratory support: used in infusions or inhalations for coughs, bronchial irritation.
• Light teas or steams have been used traditionally for dry, irritating coughs and tight chests.
• In many systems, angiangi is seen as a “lung ally,” especially in cool, damp conditions.
Cautions: usnic acid can be hepatotoxic when taken internally in concentrated form; avoid unsupervised oral use, especially with preexisting liver conditions or combined with other hepatotoxic substances. Pregnant/breastfeeding people and children should avoid internal use unless directed by a qualified practitioner.
• Avoid high-dose extracts, capsules, or strong tinctures without experienced guidance.
• Topical use is generally considered lower risk, but still patch test on a small area first.
Traditional use
Used worldwide by Indigenous and rural communities (including Māori, Native American, and European folk traditions) as a topical antiseptic and wound dressing.
Employed in poultices, dressings, and smoke/inhalation remedies for respiratory complaints and chest colds.
Sometimes used as a mild dye or deodorizer; historically carried as an emergency antibiotic dressing on journeys.
Cultural context varies—harvest and use often follow specific local knowledge and customary respect for ecosystems.
• In some European traditions, usnea was tucked into packs or medicine bags as a “go-to” forest bandage for travellers and shepherds.
• In parts of Aotearoa, angiangi has been incorporated into rongoā practice, often alongside other native plants, guided by local tikanga and mātauranga.
• Some Native American groups used usnea as both a physical and spiritual remedy, particularly for lung and skin issues.
• Across cultures, its use is typically modest and situational, not as a heavy, everyday internal medicine.
Physical properties
Organism: fruticose lichen (genus Usnea), commonly called “old man’s beard,” “tree beard,” or regional names such as Angiangi.
Appearance: bushy, pendulous, branched strands; pale green to gray-green when moist, paler or yellowish when dry.
Texture: elastic and spongy when moist, brittle when dry; central cord (axis) gives tensile strength.
Habitat: grows on bark and twigs of trees and shrubs in clean, often humid air environments (sensitive to pollution).
Chemical: contains usnic acid, other depsides/depsidones, and polysaccharides; these contribute to antimicrobial activity and yellowish coloring.
Growth: slow-growing; sustainable harvesting recommended due to ecological sensitivity and slow regeneration.
Identification tip: when gently pulling a strand apart, a fine white, stretchy inner core can often be seen—this helps distinguish Usnea from some similar-looking lichens.
Harvest guidance: many practitioners prefer to collect only fallen pieces from branches after wind or storms rather than stripping living trees.
Metaphysical / Energetic properties
Purification: used in spiritual cleansing rituals and smudging to clear negative energy.
• Added to cleansing bundles, baths, or bowls of water placed in rooms to “absorb” heaviness or stagnant vibes.
• Sometimes burned in very small amounts with other herbs to symbolically clear old patterns.
Protection: carried or hung as a talisman for guarding home, journeys, and the wearer.
• Strands may be tied above doorways, on walking staffs, or in travel pouches as a gentle guardian of space.
• Its presence in the trees can be seen as a soft, watchful presence in the forest.
Healing and resilience: associated with strengthening, endurance, and recovery—used in spells or meditative practices to support physical/emotional healing.
• Its slow growth and ability to survive in exposed places make it a symbol of quiet, long-term resilience.
• Can be held or placed nearby during rest, breathwork, or recovery practices to invite patience and gradual healing.
Connection to nature: fosters attunement to forests, ancestral spirits, and earth wisdom; used by some as an aid to intuition and dream work.
• Sitting under trees adorned with angiangi can deepen a sense of being held by the ngahere/forest.
• Some people place small amounts on an altar or near a dream space to support clearer inner listening and guidance.
Use respectfully: many traditions emphasize ethical harvesting and honoring the plant/lichen spirit.
• Take only a little, and only where it is abundant, acknowledging the slow time it takes to grow.
• Offer thanks to the land and trees that host angiangi, and avoid harvesting from polluted or damaged areas.
