Young Milky Pine (Alstonia scholaris) |
The importance of plant
names in the local language is an example of a complex structure of meaning. Different plants are used for
specific purposes in our traditional societies. The same plant known by a
common name can have sacred names to different people. Most often these sacred
names are linked to myths, rituals, and spiritual powers. Many people know the
general names for plants, but different species have a different name or an
additional word to indicate colour, wild plants, domesticated plants, or
cultivated.
Where plants have
medicinal and ritual values they may have sacred names known only to those who
claim ownership of the plant and its powers. The tanget (Cordyline fruticosa),
for example, is generally known in Nagum Boiken language as hawa. This name includes the cultivated
ones, which are red in color and appears in long and short round leaves. The
green wild ones are also known as hawa.
To differentiate the colors, the Nagum Boikens name the green wild hawa
as ofui hawa and the domesticated red
one as kli hawa. The hawa is an important plant used in
medicine and rituals. It carries secret names known only to people who use the hawa
for its spiritual power. For example, the kli hawa used by a family
in Ulighembi is known by two names: Haiwanka and Yarawali. These names are
linked to the original two brothers who began the practice of maiye sorcery. The evocation of these
sacred names with the use of hawa for
protection purposes is restricted to the family with the right to these names.
The names of plants
have deep roots in the customs, ritual, cosmology, belief system and history of
a people. Most plants have a spiritual connection or are linked to the gods of
these plants. Learning the local names of these plants helps us to understand
their importance in traditional medicinal practices in the indigenous
cosmology, and in the psychological practices of the people. It is easy to
overlook the significances of each plant in society.
Medicinal plants are
connected to the belief system, the mythological cosmos, and the cultural
practices of the Nagum Boikens. The use and adaptation of plants in various
rituals and human activities are necessitated by circumstances that are
necessary for the survival of the people. In Kemabolo village of Rigo district,
Central province, for example, where much of the environment is dominated by
savannah kunai grass (Imperata cylindrica) and kangaroo grass
(Themeda australis), with scattered
growth of eucalyptus gum trees, and a small growth of insidious forest along
the water course, the incidence of snakebite is relatively high.
More than five plants (Semicarpus sp, Passiflora foetida, Hyptis,
Piper betle Samanea, Carica papaya) are used as medicine for snakebites.
The high number of usages of many plants for one purpose in one area alone
suggests that protection of these plants is high in the conservation psychology
of these people. There is also the suggestion that people in this area have a
vast knowledge of using different plants to cure snakebites. On the other hand
there is the possibility of borrowing of knowledge from other others to
supplement what they already have on medicinal plants that can cure snakebite.
Take for example the
Milky Pine plant common in many lowland coastal areas. The Alstonia
Scholaris (Common name: Milky Pine) and Alstonia Spectibilis (Common
name Mountain Milky Pine) are used for variety of illnesses around the country.
In Waria, I collected both species, which were considered very highly by the
medicine men. The Ino (Alstonia spectibilis) and Nungwa (Alstonia
scholaris), both were used for bronchitis and asthma. Nungwa (Alstonia
scholaris) was considered very strong in its use for sexually transmitted
diseases and malaria.
In Kemabolo the
Mountain Milky Pine (Alstonia spectibilis) is used for treatment of
asthma, beside its use in gardens as shade trees for banana trees. In parts of
Morobe, Alstonia spectibilis is used to treat malaria, fever, and
stomachache. The bark, latex, and leaves are used. In Normanby Island and parts
of Central Province the plant is used to treat coughs, applied to coughs, and
used as poison antidote (Woodley 1991: 19). The chemical component of the plant
is that the alkaloids ditamine, echitamine, echitenine and alstonamine are
present (Woodly1991: 19; Manske, 1965). The plant is a chemically active plant.
The chemicals present in Alstonia spectabilis are also present in Alstonia
scholaris, which has additional alkaloids echitamidine, picrinine (Manske,
1970) and picralinal.
Ellen Woodley reports
that the Alstonia scholaris is widely used in Papua New Guinea against
malaria. The plant is used for abdominal pains in the Sepik and the Northern
province, for cough on Normanby Island and for gonorrhea in Milne Bay. Other
uses reported are for asthma, hypertension, lung cancer and pneumonia in Manus,
Indonesia, Malaysia and the Philippine (Burkhill 1966; Warburg 1899,
Steenis-Kruseman; Woodley 1991: 17). These two plants are impressive in their
medicinal properties and in their usefulness to many people in the country. The
Nagum Boiken name for Alstonia scholaris
is hembe, which is used for asthma,
fever, and for hair dye.
Plants such as Alstonia scholaris (Milky Pine) or Alstonia spectabilis (Mountain Milky
Pine) must be properly researched on for extraction of their medicinal products.UPNG
researchers Gelenta Salopa and Prem P. Rai of UPNG in collaboration with Han
Wohlmuth of Southern Cross University, Australia, reported in 2009 at the UPNG
Science conference that the Alstonia scholaris
had the potential for full development.
My view is that there
is a need for research and product development of medicine derived from our
local biodiversity. Investment in product development should be our next phase
of national development. We need to develop our own medicinal products from the
natural environment we are blessed with. We can do it if we work together.
The important message I
want to bring across here is that we must do everything possible to preserve
the traditional knowledge systems of our communities. A shift of paradigm in
research and product development is needed for PNG today.
