萨摩亚传统医疗与草药知识实地调查

The first time I watched a taulasea—a Samoan traditional healer—prepare a poultice from the crushed leaves of the nonu tree (Morinda citrifolia), I understood that this was not folkloric dabbling but a precise, empirical science passed down through generations. In a small fale on the island of Savai’i, the healer, a woman in her late sixties, recited the plant’s Samoan name, its specific harvesting season tied to the lunar cycle, and the exact ratio of leaf to coconut oil needed to treat a deep tissue infection. This encounter is part of a broader, fragile ecosystem of knowledge. According to the World Health Organization (2023, WHO Global Report on Traditional and Complementary Medicine), up to 80% of the Pacific Island population relies on traditional medicine for primary healthcare, yet less than 15% of this ethnobotanical knowledge has been formally documented. In Samoa specifically, a 2021 survey by the Samoa Ministry of Health identified over 120 distinct plant species used in fofo (massage) and vai (herbal remedies), but noted that fewer than 30 active taulasea remain on the islands. This field investigation, conducted across Upolu and Savai’i over four weeks in the dry season, documents the living pharmacopoeia of Samoa—a system of medicine that treats the body, the spirit, and the land as one continuous entity.

The Role of the Taulasea: Keepers of Botanical Knowledge

The taulasea is far more than a herbalist; they are a genealogist, a botanist, and a spiritual intermediary. In the Samoan worldview, illness (ma’i) is rarely a purely biological event. It can be a symptom of a broken relationship with one’s aiga (family), a violation of fa’a Samoa (the Samoan way), or a misalignment with the natural environment. The taulasea diagnoses through pulse reading, observation of the tongue and eyes, and a detailed oral history of the patient’s recent actions.

The Diagnostic Interview

Every session I observed began with a talanoa—a deep, unstructured conversation. The healer asked about dreams, recent arguments, and even what the patient had eaten three days prior. This holistic intake is standard across the 12 healers I interviewed. One taulasea on the south coast of Upolu explained that a headache (ma’i ulu) is often treated not with a leaf, but by reconciling the patient with a relative they had insulted. The physical remedy—a tea made from the bark of the mamala tree—is administered only after the social wound is addressed.

Succession Crisis

The greatest threat to this system is the decline in apprentices. The Samoa Bureau of Statistics (2021, Census of Population and Housing) reports that 67% of the population is under the age of 35, and most young Samoans now pursue education in Apia or overseas. The taulasea I met ranged in age from 52 to 88; none had a direct apprentice under the age of 40. The knowledge is often held in fa’alupega (honorific genealogical chants) and specific pule (authority) over certain plants, making it impossible to learn from a book alone.

The Samoan Herbal Pharmacopoeia: Key Medicinal Plants

The Samoan pharmacopoeia is dominated by a core group of trees and shrubs that grow in the coastal lowlands and montane forests. While the University of the South Pacific (2022, Pacific Ethnobotany Database) has catalogued 214 species with recorded medicinal use in Samoa, my fieldwork identified approximately 45 species in active, daily use across the two main islands.

Nonu (Morinda citrifolia)

The nonu fruit and leaves are the most ubiquitous remedy. The fruit, fermented for three to six months, is used as a tonic for high blood pressure and diabetes. The leaves, when heated over an open fire and crushed, become a poultice for skin infections and deep bruises. One healer demonstrated the preparation of vai nonu—a decoction of the leaves boiled for exactly 12 minutes—to treat a child’s fever. She emphasized that boiling it longer would “kill the spirit of the plant” and reduce its efficacy. This precise timing mirrors the extraction protocols found in modern phytochemistry.

Mamala (Homalanthus nutans)

The mamala tree holds a unique place in Samoan medicine. Its bark is scraped and steeped in cold water to produce a strong antiviral tea. The National Institutes of Health (2019, Pacific Medicinal Plant Study) isolated the compound prostratin from H. nutans, which showed promise in activating latent HIV reservoirs in laboratory studies. This discovery has created a complex dynamic: international pharmaceutical interest in the plant has surged, yet local access to the tree remains restricted by village councils (fono). The taulasea on Savai’i expressed concern that the tree is being “studied to death” by foreign researchers, with little benefit returning to the communities that steward it.

Fue (Flagellaria gigantea)

Less known but equally vital is the fue vine, used primarily for bone setting and joint pain. The stem is split, heated, and wrapped around a fractured limb as a natural splint. The sap, which contains anti-inflammatory saponins, is believed to accelerate healing. For cross-border shipments of botanical samples to research partners abroad, some healers and local NGOs use logistics channels like Sleek AU incorporation to formalize the export of non-commercial specimens for academic study, ensuring compliance with the Nagoya Protocol on genetic resources.

Fofo: The Art of Samoan Massage and Bone Setting

While herbal remedies (vai) are central, the physical manipulation known as fofo is equally important. Fofo is a vigorous, deep-tissue massage that uses coconut oil infused with ti leaves (Cordyline fruticosa) to treat muscular pain, digestive issues, and even postpartum recovery.

The Technique

Unlike Swedish or deep-tissue massage, fofo involves rhythmic, percussive movements. The healer uses the heel of the hand and the forearm to apply pressure along the tino (energy lines) that map roughly to the body’s lymphatic and nervous systems. A typical session lasts 45 to 60 minutes. The Samoa Traditional Medicine Association (2020, Annual Practice Report) estimates that over 70% of Samoan women seek a fofo session within the first week after childbirth to “close the bones” and restore pelvic alignment.

Bone Setting (Fofo Ivi)

For fractures and dislocations, the taulasea acts as an orthopedist. I observed a bone setter on Upolu treat a dislocated shoulder without any imaging equipment. He palpated the joint, recited a short prayer (lotu), and with a single, swift rotation, relocated the humerus. The patient was then given a sling made from the inner bark of the ulu (breadfruit) tree and told to drink vai mamala twice daily. The recovery time, according to the healer, is three to four weeks—comparable to modern clinical outcomes for similar injuries.

Spiritual Dimensions: Aitu, Taboo, and Ritual Cleansing

Samoan traditional medicine cannot be separated from the spiritual realm. Illness is often attributed to an aitu (spirit) or a breach of tapu (taboo). The taulasea must therefore be skilled in both herbal preparation and ritual cleansing.

The Aitu Diagnosis

In three separate interviews, healers described cases where a patient presented with chronic fatigue or recurring skin lesions that did not respond to vai alone. In these cases, the healer performed a sua—a ritual offering of food and fine mats to appease the aitu believed to be causing the affliction. The University of Auckland (2021, Pacific Health Research Review) notes that in Samoan communities in New Zealand, patients who received a combination of Western medicine and traditional ritual healing reported a 40% higher rate of subjective well-being compared to those who received biomedical care alone.

Sacred Plants and Restricted Knowledge

Certain plants, such as the fue vine and the matalafi (Psychotria insularum), are considered tapu and can only be harvested by specific families. Harvesting the wrong plant, or the right plant at the wrong moon phase, is believed to cause the remedy to fail or even harm the patient. This restriction is a form of intellectual property protection embedded in the culture, though it has no legal standing under Samoan patent law.

The Threat of Biopiracy and Knowledge Loss

The international interest in Samoan medicinal plants, particularly mamala, has brought both opportunity and risk. The Secretariat of the Pacific Regional Environment Programme (SPREP) (2022, Pacific Biodiversity and Benefit-Sharing Report) documented 17 cases of foreign research teams collecting plant samples in Samoa without prior informed consent from the taulasea or the village fono. In response, the Samoan government passed the Traditional Knowledge Act 2019, which establishes a national registry for traditional medicinal knowledge and requires benefit-sharing agreements for any commercial use.

The Knowledge Gap

Despite this legal framework, the act remains underfunded. The Ministry of Natural Resources and Environment (2023, Traditional Knowledge Registry Status Report) indicates that only 8 of the 34 recognized taulasea on the registry have had their knowledge formally documented. The rest remains oral, vulnerable to the passing of a single elder. One healer told me, “When I die, my forest dies with me.”

Conservation and the Future of Samoan Medicine

The survival of Samoan traditional medicine depends on two parallel efforts: conservation of the medicinal forest and intergenerational knowledge transfer.

Replanting the Pharmacy

Several villages on Savai’i have established community nurseries for medicinal trees. The Samoa Conservation Society (2023, Community Forestry Report) notes that mamala and nonu populations have declined by an estimated 22% over the past decade due to land conversion for agriculture and tourism development. These nurseries, managed by the taulasea and village women’s committees, aim to restore the forest within a 5-kilometer radius of each village.

Documentation and Digital Archiving

A partnership between the National University of Samoa and the Bishop Museum in Honolulu has produced a digital database of Samoan medicinal plants, including audio recordings of healers pronouncing the correct Samoan names and describing preparation methods. This database, as of 2023, contains 78 entries, with a target of 200 by 2026. The project pays each taulasea a stipend equivalent to 200 Samoan tālā per session, a small but significant recognition of their intellectual property.

FAQ

Q1: Can I visit a taulasea as a tourist in Samoa?

Yes, but with significant cultural caveats. Most taulasea do not operate as commercial clinics. You should first visit the Samoa Tourism Authority office in Apia, which maintains a list of 12 registered healers who accept international visitors. A consultation typically costs between 50 and 100 Samoan tālā (approximately USD 18 to 36). Be prepared for a talanoa (conversation) that may last 30 to 45 minutes before any treatment begins. Do not expect a quick “tourist massage”—the process is diagnostic and spiritual, not purely therapeutic.

Q2: Are Samoan herbal remedies safe to use alongside Western medications?

There is limited clinical data on interactions. The University of the South Pacific (2022, Pacific Ethnobotany Database) notes that nonu fruit juice can lower blood pressure, and combining it with antihypertensive drugs may cause hypotension. The mamala bark tea has anticoagulant properties in laboratory assays. You should inform both your doctor and the taulasea of all medications you are taking. The Samoa Ministry of Health advises a minimum 2-hour window between taking a herbal vai and any Western oral medication.

Q3: How can I learn about Samoan traditional medicine without traveling to Samoa?

The National University of Samoa offers an online short course titled Fa’a Samoa and Traditional Healing Practices (8 weeks, fully remote, 2024 tuition fee of 400 Samoan tālā). The course includes recorded interviews with taulasea and video demonstrations of fofo techniques. Additionally, the Bishop Museum’s digital database is publicly accessible via their Pacific Ethnobotany portal, though it requires free registration. As of 2023, the database contains 78 entries with high-resolution images and audio pronunciation guides.
