    Decolonizing the Forest: How Philippine Native Trees Can Uproot Neocolonialism Amid Climate Injustice

    Planting native trees is part and parcel of a broad process of uprooting neocolonialism and building climate resilience.

    According to Republic Act No. 10176, the Philippines observes Arbor Day every June 25. The Arbor Day Act mandates local government units to adopt a day every calendar year to commemorate the national tree-planting day. It also allows them to allot a budget and resources for annual tree-planting activities.
    As this legislation was passed in good faith, its implementation should be scrutinized. After a month of the said observance in 2021, Esquire reported that a branch of the Department of Environment and Natural Resources (DENR) distributed an invasive alien species of tree. The DENR CENRO Capas Tarlac gave 585 seedlings of various trees to passersby at the Capas Shrine Monument. This includes cashew, guyabano, narra, cacao, sampalo, atis, bignay, and, in particular, mahogany.
    In a 2016 study, the Philippine Institute for Development Studies also reported that under the National Greening Program, the most planted tree was mahogany in 2012.In a 2014 STAR article, the Department of Agrarian Reform followed suit by planting 1,200 mahogany seedlings in the agrarian reform communities in the Mindanao region. Only in June 2020 did the DENR ban the use of mahogany in replanting forests after years of campaigns by civil society organizations against the said practice. 
    Mahogany is one of the invasive alien species of trees. Tracing its origin, it usually grows in the Central and South American region and was an import brought by the American colonizers into the country after agricultural and forestry schools opened in the 1900s. Ponce (1933), as cited in Banguinon, Quimado, and Francisco (2003), documented the introduction of American mahoganies, of which there are two types: small leaf mahogany and large leaf mahogany. Banguinon, Quimado, and Francisco (2003) said that mahogany thrives in invading natural forests, which is why it spreads throughout the archipelago. Further, they also noted that “mahogany plantation is like a “green desert” to wildlife.” 

    The case against exotic trees

    In his book Philippine Native Trees 101: Up Close and Personal, former University of the Philippines Diliman Institute of Biology professor Dr. James Vincent LaFrankie Jr. emphasized the danger of non-native trees by illustrating the difference between planting molave versus mahogany:
    “Molave, as a native species, has a relationship to the land, water, and other organisms that [have] developed over a million years.
    Certain fungi live with the roots, certain insects feed on the plant parts, while others pollinate the flower. Birds and mammals live along the branches and feed on the seeds.No such relationship exists for the newcomer. The result is ten hectares of mahogany in a biodiversity-dead zone. 
    There are no birds, no insects, only a nearly dead soil due to the lethal chemicals that leak from the rotting leaves (emphasis mine). Native species are rarely found as seedlings beneath the canopy, and so, most significantly, there is no future for ten hectares of mahogany.”
    LaFrankie further expounded his stance by saying, “Native species [have] a relationship to the land, water, and other organisms that have developed over a million years.”
    With that, this only means that native trees are tied to their relationship with the land, like how land is life to our indigenous brothers and sisters. They maintain local wildlife as well as the diversity of life and adapt to environmental conditions specific to the area. Thus, exchanging them with exotic species will only do more harm than good. Exotics, especially alien invasive species, harm our food system and further deteriorate our endangered biodiversity. 
    In a BluPrint interview, Anthony Abrias of the Philippine Native Plant Conservation Society explained the advocacy behind promoting native trees: “We recognize that exotic plants have economic uses for us, such as pineapples, which are from South America. But if we’re not in the food industry, if we’re in tourism and development, then let’s develop responsibly. Since we have already lost 80 percent of our forest cover, and our wildlife [is] dependent on forests, then let’s plant trees that are native to our country.”

    Uprooting ‘neocolonialism’ 

    According to a report by the Asia-Pacific Forest Invasive Species Network, several exotic species of trees were introduced in the country with ‘good intentions’. They noted that mahogany was intentionally brought in for forest production in 1907. But one cannot deny that mahogany is also spreading at a national threat level and already pose a threat to biodiversity, as declared by the said international organization.
    That being said, it is established that mahogany, as an exotic invasive species, was introduced to the archipelago during American colonization and was a byproduct of historical colonialism, or simply colonialism.
    This is where the concept of monoculture in agriculture comes in as the demand increased in the lumber trade in the past. Abrias expounded: “We just think [mahogany] are native because at the height of the timber industry in the Philippines (mid 1960s-1980s), the dealers in the lumber trade, to simplify everything [and to ride on the demand worldwide for the prized Honduran mahogany] decided to call all our hardwoods ‘Philippine mahogany,’ whether they were white lauaan, red lauaan, apitong, mayapis, tanguile, almon, yakal, bagtican, etc.” 
    This practice was carried over as it showed itself in a different form. Here, Forest Foundation Philippines pinpointed the reason behind the usage of exotic species: “The low appreciation and understanding of ecological functions of native species in policy and programs have led to reforestation activities that use exotic species.”
    Recently, mahogany placed in the top three in terms of log production on average in the last five years, according to the reports of Philippine Forestry Statistics.
    While it is alarming, this also signals an opportunity to dig deeper into environmental movements and listen to Filipino scientists, civil society organizations, and indigenous people. This serves as a way of uprooting neocolonialism, and planting native trees is one of many ways to decolonize our forests. 
    The non-profit organization appealed to bring back Philippine native tree species: “By prioritizing native species in restoration activities, environmental and livelihood benefits would eventually help reduce poverty.”
    The organization also reminded everyone to look beyond the economic valuation of the forest ecosystem and said that forest restoration should go beyond satisfying human needs in terms of livelihood, wood products, and food security. 
    Switching to local-based natural solutions for conservation would also be a win for decolonization efforts in the country. Nothing less than dismantling an economic system that jeopardizes the sacred connection between people and the planet must be embraced to create the conditions for true and long-lasting conservation of our native trees.

    Strengthening climate resilience

    The fact also remains that not everyone is equally impacted by climate change. Especially under the blanket of neocolonialism in the present, those who contributed the least often suffer the most.
    Like the Philippines, which has been experiencing forest cover loss that impacts some 80 million Filipinos who depend on the forests for their resources, the European Tropical Forest Research Network noted that the country “is one of the most severely deforested countries in the tropics, and most deforestation has happened in the last 40 years.”
    Conservation storyteller Celine Murillo explained in her Rappler article the most appropriate way to tackle environmental rehabilitation: “[F]irst, do a species-site matching. This is an important step that determines which species are suitable [for] a location, assessing properties, endemicity (whether native or exotic), growth rate, variety, and other requirements.”
    Murillo also contended that planting native trees is one of the many climate solutions.
    Indeed, planting native trees may not be the sole answer or cure-all to systemic climate injustice, but doing this will definitely undo some damage that humans have done to the atmosphere. 
    Coupled with calls for cutting down on fossil fuel use and other natural solutions, planting native trees is also a way to respect our indigenous roots and honor Mother Earth.
    Lastly, to quote Abrias: “There’s a Chinese saying that goes, ‘The best time to plant a tree was 100 years ago.’ To that we add: ‘The next best time to plant is to plant a native tree today.’

  • From Plant to Pill: Harvesting the Medicinal Potential of Philippine Plants

    From Plant to Pill: Harvesting the Medicinal Potential of Philippine Plants

    When someone falls ill, it is fairly common practice in the Philippines to hear an elder recommend some form of herbal remedy. Obtain the leaves of this plant from a neighbor’s garden, from the wet market, or from a shrub last seen sprouting freely at the side of a certain road. Take them home and boil them, then drink the concoction like tea. Some of the more familiar remedies include: tawa-tawa for dengue, oregano for cough, guava/bayabas for washing wounds, ampalaya for diabetes, and serpentina for high blood pressure. Drink the tea from their leaves, they say. And you will surely be cured of your illness in no time. But how do we know if these herbal remedies are effective, and more importantly, safe? Are there any side effects if consumed in excess? How many leaves is one supposed to boil, and for how long? What are the standards and guidelines, and are there any to begin with?Tawa-tawa leaves, for instance, have been used extensively in folkloric and traditional medicine in the treatment of dengue since the 1980s[1]. They have been observed anecdotally to combat the sudden drop in platelet count experienced by dengue patients.[2] However, for the longest time, the medical community regularly cautioned against their use due to the absence of any clinical studies showing proof of their safety, efficacy, and dosing. [3] [4]This is typical for any herbal plant used in treating illness. Skepticism from the scientific community is expected, and justified, as unproven treatments may cause more harm than good in the path to recovery and healing.

    Philippines, a biodiversity hotspot

    It makes sense that many of us, especially those residing in rural areas, resort to plants as medicinal remedies. After all, the Philippines ranks among the top 17 in the world in terms of most diverse natural resources [5], with 10,107 species identified and documented to date[6]. About half of these species are endemic or found only in the Philippines[7]. This places us in a favorable position to capitalize on the vast untapped potential of plants with medicinal properties and compounds from which natural products can be derived.

    Is there a way that herbal plants could undergo the same rigorous research, development, and testing that synthetic drugs do, so that they may be accepted and eventually integrated into mainstream medicine?

    Developing drugs from natural products

    Other countries have already been successfully doing this for decades. One US study reports that natural products have been utilized in the discovery and development of over 50% of all new drug entities approved by the US Food and Drug Administration in the last 39 years –particularly in developing new anti-cancer, anti-hypertensive, and anti-bacterial/anti-viral drugs[8] [9]. The Chinese herbal medicine market itself has been around for centuries, bringing in annual revenues of up to USD 18 billion[10].What would harnessing the medicinal potential of our plants mean for us?Less dependence on multinational pharmaceutical companies, for one. Many medicines available in the market today are produced and distributed by global conglomerates (think Pfizer and GlaxoSmithKline), making health treatment expensive and inaccessible for all Filipinos. Maintenance medicines and antibiotics typically set people back by anywhere from P500 to P5,000 a month. This just isn’t affordable for everyone, and homegrown alternatives from local plants, if they could be developed, would go a long way in bringing down the barriers to access for treatment, especially for those in far-flung and disadvantaged communities. Medicinal herbal gardens could further be grown at the barangay level, increasing the self-sufficiency of our people.Not only that, successfully developing even a single drug or herbal supplement that is proven effective through multiple clinical trials, could create opportunities for us to export these products abroad. The market potential is huge – the global herbal medicine market is valued at USD 151 billion as of 2021, and is projected to double to USD 347 billion by 2029[11]. Even one herbal supplement, for instance a tablet with anti-hypertensive properties, could be sold to the 1.5 billion people in the world who suffer from hypertension[12]. In the process, the economic gains would also extend to our farmers who would benefit from cultivating the related plant crops.This begs the question – are we already late to the game?

    Early efforts

    In 1974, the National Integrated Research Program on Medicinal Plants (NIRPROMP) was formed with the hope of developing a Filipino pharmaceutical industry and addressing the aforementioned issues.[13] Spearheaded by UP Manila and funded by the DOST, it was tasked with studying and scientifically validating traditional herbal remedies. [14]Interviews were conducted with 1,000 herbolaryos (traditional healers), and plants were surveyed and selected for further study based on their potential to treat the most common health problems in the country.[15]  The result of these studies was a list of 10 plants or “Sampung Halamang Gamot” that were identified as safe, effective, and sustainable[16]. The list was officially endorsed by the DOH to the public in 1995.From this list, lagundi and sambong garnered the most interest, and were consequently developed into various formulations – tablets, capsules, and syrups.[17] Today, herbal drugs from both these plants are considered to be the most commercially successful products of NIRPROMP’s efforts, and are currently valued to be a Php1 billion industry[18]. Ascof lagundi and re-leaf forte sambong are now household brand names with widespread acceptance from the medical community.This goes to show what can be accomplished when the academe, the government, the medical community, and the private sector work hand-in-hand.Beyond the success of lagundi and sambong products from the 1990s however, progress has been slow. Several challenges have been hampering efforts to develop more herbal drugs. Lack of allocated funding for research and development, excessive red tape surrounding the release of funds and reimbursement of expenses for research, and the low pay and incentives for researchers, are among the obstacles facing the industry today.[19] [20] [21]

    Where are we now?

    In 2011, the government revitalized its commitment to herbal medicine development by launching the Tuklas Lunas program (“cure discovery”), which now forms part of the country’s national health agenda.[22] Launched by DOST’s Philippine Council for Health Research and Development (PCHRD), its mandate is “to produce world-class medicines derived from the biodiversity of the Philippines[23].” It is currently the leading program for herbal drug discovery in the country.29 universities and institutions across the country (18 in Luzon, 6 in Visayas, and 5 in Mindanao) have been designated as Tuklas Lunas Centers, each serving as research hubs to help maximize the exploration of plant species unique to various locations.[24] As labs across the country are established, hundreds of plants are now being simultaneously studied for their potential anti-cancer, anti-diabetic, anti-inflammatory, and anti-hypertensive properties.[25] A comprehensive list of ongoing Tuklas Lunas projects can be found here and here.

    Recent breakthroughs

    In 2012, one of the first research papers confirming the platelet-increasing properties of tawa-tawa leaves was published by a group of researchers from UST[26]. More studies have been published since[27], and in 2019, a standardized tawa-tawa herbal supplement capsule, called Daily Apple Tawa-Tawa, was released by Herbanext Laboratories in partnership with the DOST[28]. Another drug formulation was released the same year by Pharmalytics Corp in partnership with De La Salle Medical and Health Sciences Institute, which is part of the Tuklas Lunas program.[29] Clinical trials are now underway to determine both capsules’ efficacy as complementary treatments for dengue[30].  With the successful completion of clinical trials, it is hoped that dengue medicine will be the next major plant-to-pill success story since lagundi and sambong.

    Our role

    If we are to reap the full benefits of our country’s plant biodiversity, we must elect government officials who understand the value of scientific research and its role in developing affordable Philippine herbal medicines as a means to addressing our country’s health problems. We need voices in government that will advocate for science funding, support our national scientists, and promote a culture of scientific literacy.

    It has taken several decades for us to get from anecdotal evidence to herbal supplements and medicines for the lagundi, sambong, and tawa-tawa plants.  Funding remains one of the major challenges holding back our herbal medicine industry. Drastic budget cuts in the departments of health, science, and education delay progress for drug development projects, while small grants are insufficient for rolling out large-scale clinical trials[31] [32]. There is greater need for government to prioritize health research investment.If we are to reap the full benefits of our country’s plant biodiversity, we must elect government officials who understand the value of scientific research and its role in developing affordable Philippine herbal medicines as a means to addressing our country’s health problems. We need voices in government that will advocate for science funding, support our national scientists, and promote a culture of scientific literacy. Perhaps our scientists themselves could consider running for public office, a phenomenon that is gaining interest and traction in other countries  [33]. The future landscape of this industry is expected to rest heavily on political will. That being the case, it starts with us, an informed citizenry. Keeping abreast of the latest scientific research and developments will allow us to assess the platforms and priorities of those who run for office. Educating ourselves on the richness of the plants that surround us could be a smaller first step – the next time an elder prescribes an herbal remedy, ask them questions or lend a hand in preparing the tea. Go look at the tree from which the leaves came, and marvel at how medicines come from our natural environment.Hopefully, with the spirit of curiosity and inquiry, the work continues and more medicine is discovered and developed from the abundance of the plants that surround us.  Disclaimer: Always seek medical advice and diagnosis from medical professionals.
