2Ethnopharmacological Studies
Introduction
Modern medicine vs Traditional medicinemodern medicine improved health care, high
cost and unavailability of modern medicine led to continued dependence on MPs.
“Albularyos” and their use of MPs are still widely practiced in rural areas of the country.
DOH endorses “Sampung Halamang Program”Still no systematic research strategy in
identification, characterization and evaluation of MPs used by “albularyos”.
3Ethnopharmacological Studies
Importance of the topicProblem: Poverty; No access to health care. Need alternative sources of medication. Increased income for farmers and significant
contribution to the national economyIncreased awareness and attention on MPs
Results of the researchCharacterization and evaluation of our biodiversityServe as baseline or database for further studiesused by DOH to evaluate health practices of
Pulilan.Exposure for the students: community based study
and explore ethnopharmacology in the Phils.

11Ethnopharmacological Studies
12Ethnopharmacological Studies
- Tested the curative effects of herbal medicines
- Handed from generations to generations
- Moral support and psychological comfort from patients
- High social status and are well respected
13Ethnopharmacological Studies
Modern drugs- cheaper- decline of herbal medicines popularity
1992 - Administrative Order No.12- Traditional Medicine Program- Senator Juan Flavier- Promotion of Traditional Medicine
RA 8423Traditional and Alternative Medicine Act
(TAMA)14Ethnopharmacological Studies
Philippine Institute of Traditional and Alternative Health Care (PITAHC)
“Traditional and alternative health care in the hands of the people”
- A Government owned and controlled corporation (GOCC)
- To deliver the traditional alternative health care.
15Ethnopharmacological Studies
Alternative Healthcare - used in the prevention, diagnosis and elimination of physical or mental disorder
Traditional Medicine Recognized by the peopleinterrelations based on culture, history,
heritage and consciousness
16Ethnopharmacological Studies
According to the DOH, the health sector falls short due to:
- inappropriate health delivery system - inadequate health regulatory mechanisms- poor health care financing

18Ethnopharmacological Studies
scientific study that correlates ethnic groups, their health practices, and how it relates to their physical habits and methodology in creating and using medicines
incorporates the social science of ethnology and the medical science of pharmacology.
it explores medicinal plants in indigenous cultures.
methods of collection, extraction, preparation – allowed safe usage of the substance and its safety record
19Ethnopharmacological Studies
- Documentation of indigenous medical knowledge
- Scientific study of indigenous medicines
- Search for pharmacologically unique principles from existing indigenous remedies.
20Ethnopharmacological Studies
- interviewing healers
- interpreting traditional terminologies into their modern counterparts
- examining patients consuming herbal remedies
- identifying the disease for which an herbal remedy is used
21Ethnopharmacological Studies
- Interpretation of signs and symptoms
- Clinical studies on herbs and their interaction with modern medicines
- Advising pharmacologists
- Strengthen traditional system of medicine in a community
22Ethnopharmacological Studies
Collection of information from local population concerning the use of regional medicinal plants, identified the most important species used and calculate the Informant consensus factor (ICF). The collection of data relied on a qualitative interview (Aburjai et al)
23Ethnopharmacological Studies
- 92 traditional medicine practitioners/healers were interviewed to collect information on the use of herbal treatments
- Information was also collected on the method of preparation, dose and duration along with the botanical names, family and local names of the medicinal plants (Hedge et al).
24Ethnopharmacological Studies
- Performed door-to-door visits in order to identify the local people with specialized knowledge on the use of the medicinal plants.
- By using the snowball method, the names of other specialists were obtained.
- Calculated the Informant consensus factor (ICF) for the data analysis.
- The rural dwellers of the community helped in collection of the information.
25Ethnopharmacological Studies
People who have knowledge on traditional medicine.
Individual Interviews
Open and semi-structured questions
More than one interview session took place
26Ethnopharmacological Studies
Local representatives help in identifying folk herbalists (Gazzaneo).
The local people guide in locating the folk herbalists (Akerreta).
The chosen folk herbalists have no scientific knowledge on the medicinal plants (Akerreta).
The interviewees are born or live most of their lives in the studied region (Akerreta).27Ethnopharmacological Studies
According to WHO, traditional medicine is still being used by 80% of the world population as part of their health care, especially those in developing countries.
Many African countries including Tanzania, depend on traditional healers who provide primary health care by taking care of people living with emerging diseases such as HIV/AIDS (Kisangau).
28Ethnopharmacological Studies
29Ethnopharmacological Studies
3 criteria of triangulation
Endorsement from Barangay Health Care Office
Confirmation from folk herbalists
Interview by researchers
BHCO refers traditional medical practitioners/folk herbalists in the area
Health Care Officers (HCO) and Barangay Health Workers (BHW)
verifies authenticity of referred folk herbalists
HCOs and BHWs fills up rubric sheet to quantitatively assess the recommended
folk herbalists
Self assessment of folk herbalists using rubric sheet facilitated by
researchers
Researchers divide themselves to 5 groups, each group interviewing 2 to 3 folk
herbalists
Following a standard questionnaire folk herbalists would be asked to provide information on indications,
parts of the plant used, preparation and route of
administration.
Researchers will also fill up a rubric sheet
Score of each folk herbalist from the 3 criteria will be averaged. A score of < 75 would indicate unreliability, whereas a score of > 75
indicates reliability and gives credibility to the folk herbalist.

47Ethnopharmacological Studies
• Indications will be grouped into 10-20 categories• Based on the indications of the Sampung
Halamang Gamot• Informant Consensus Factor (ICF)• Fidelity Level (FL)• comparison between the herbal plants used
by the folk herbalists and those included in the Sampung Halamang Gamot
48Ethnopharmacological Studies
• Informant Consensus Factor (ICF)– will be used to identify agreements of the informants
on the reported cures for the groups ailments
ICF = (nur – nt) / (nur – 1)
where nur = number of use citations in each category
nt = number of species used

• Fidelity Level (FL)– percentage of informants claiming the use of a certain
plant for the same major purpose
FL(%) = (Np / N) x 100
where Np = number of informants that claim a use of a plant species to treat a particular disease
N = number of informants that use the plants as a medicine to treat any given disease
