RESEARCH INFORMATION SERIES ON ECOSYSTEMS Volume 14 No. 2 May – August 2002 Propagation Management Of Herbal and Medicinal Plants by Eduardo B. Principe and Aurora S. Jose 2 Foreword This issue contains the first part of a series of information on the propagation management of medicinal plants. Medicinal plants abound in the country. They used to be sleeping treasure due to lack of knowledge on their importance and uses in alternative health care, limited research on the development of photochemical components of the plants, and other related R & D undertakings on herbal products and medicines.
We have consolidated relevant data and outputs of the training and pilot research conducted by ERDB on the integration of medicinal plants as agroforestry crops in the upland areas to provide useful information for farmers (upland or lowland) cooperatives, corporations, and other interested individuals. Production of medicinal plants in small or large-scale plantations will provide the pharmaceutical industry enough supply of raw materials. Propagating medicinal plants, especially in upland areas will not only be economically beneficial to the local people, but it will also help maintain a rich biodiversity in the ecosystem.

One of the concerns that go with population increase is the problem on people’s health. The high cost of western medicines and treatment resulted in the growing number of self- medicating people. Many have also resorted to traditional medicines, thus the growing demand for natural products. Aside from financial considerations, people opt for natural products because they have become concerned of what they use as food and medicines. With this situation, the Department of health through the Philippine Institute f Traditional Alternative Health Care (PITAHC) under Republic Act No. 8423 endorsed the use of traditional medicines in the country. Medical plants abound in nature. Since most of them are available and easily accessible, these medicines are more affordable compared to synthetic drugs. Ten medicinal plants have been endorsed by the DOH-PITAHC, after they have been scientifically validated to ensure safety and efficacy. These are Acapulco, Ampalaya (Makiling variety), Lagundi (five leaflets), Bawang, Bayabas, Sambong, Niyug-niyogan, Tsaang-gubat, Yerba Buena, and Ulasimang bato (pansit-pansitan).

D. Drying medicinal plant parts Before drying the different parts of 1. Medicinal plants, they undergo some tests to be sure that: moisture content of dried materials is ;10%; not moldy, without other pests, parts of other plants, nor stones and soil particles; microbial count and heavy metals are within allowable amounts; poisonous microorganisms are absent; no pesticides residues efficacy is almost similar to the standards. 7 2.
Microbial test requirement Standard plate count – 10 cfu/g Coliform plate count – ;10 cfu/g Molds and yeasts plate count – ;10 cfu/g E. coli – negative Salmonella – negative Staphylococcus aureus – negative 3. Heavy metal analysis Allowable Amount Lead (Pb) 10. 0 ppm Cadmium (Cd) 0. 3 ppm Chromium (Cr) 10. 0 ppm Argon (Ar) 3. 0 ppm E. Additional safety guidelines on using medicinal plants 1. Do not take for granted the identification of the herb. 2. Use only the recommended amount for the recommended period. 3. If you’re over 65 and sensitive to drugs, start with low-strength preparation. . Be extra cautious if you have chronic diseases. 5. Pay attention to any symptoms of toxicity. 6. Be extra careful when using herb oil. 7. With few exceptions, pregnant and nursing women should not use healing herbs as medicines without doctor’s advise. 8. With few exceptions, healing herbs should not be given to children below 2 years old without doctor’s advise. Role of the Ecosystems Research and Development Bureau, DENR 1. The ERDB with the project on medicinal plants will directly manage and provide technical assistance, as follows: The farmer-beneficiaries will be trained on the production and management of edicinal plants to be spearheaded by ERDB. The research team of ERDB will provide the technology using organic fertilizer, fungicide and pesticides. The farmer-beneficiaries will be trained on the medicinal livelihood options, like herbal soap making, ointment preparation, herbal tea production and planting stock production. At the same time, household use on proper preparation and use of medicinal plants for alternative health care will be taught, such as decoction and other uses of medicinal plants for health care. 2. The farmer’s activities will be supervised and monitored by ERDB research team.
They will mutually coordinate their plans and directly implement the production management to enhance productivity of the land. 8 3. The ERDB will be responsible in the overall production and management of high- value and high priority medicinal plants. 4. The ERDB research team will be allowed and given full access to the farmer’s land to use their denuded forest land and/or farm lot to promote sustainable development for medicinal plants. 5. To support the poverty alleviation of the upland farmers through livelihood ERDB will provide and assists the cooperators in marketing medicinal products.
ERDB will be the conduit to link farmer’s medicinal products to the herbal industry, manufacturers and markets. ERDB will be responsible in formulating marketing strategies and other marketing aspects of raw materials and other related products from the medicinal plants. Role of Farmer-Beneficiaries 1. The farmer should assign and designate the working force and land to be used for medicinal plant production. 2. They should be willing to plant and cultivate medicinal plants at their own farm lot, such as lagundi, sambong, tsaang-gubat, acapulko, banaba, alagao, ampalaya and other high-value crops with medicinal use. . They will plant the herbal and medicinal plants as agroforestry crops in their farm. 4. In cultivating the medicinal plants, the farmer’s farm should be free from heavy metals and pollution (soil analysis is required). 5. The farmer should use organic fertilizer, pesticides and fungicide. 6. The farmer should render their shared free labor for the planting, maintenance, and protection of the demonstration farm. 7. There should be at least 10 to 15 interested farmers to venture on medicinal plants farming. 9 References Cruz, J. 1985. Herbal medicine: A viable alternative for the Filipino people. Marsman
