Research Article - Journal of Natural Product and Plant Resources ( 2017) Volume 7, Issue 4
The present study deals with the first-hand information of ethno-medicinal plants which are used traditionally by the
Ralte tribes of Mizoram. The treatment includes various ailments such as hypertension, tuberculosis, rheumatism,
allergies, fractured bones, jaundice, dysentery, cuts and wounds. The Ralte people of the study area represent a
well-organized tribe with unique dialect and identities. The study has revealed 106 plant species of ethno-botanical
importance belonging to 96 genera and 57 families. The need for complete inventory and documentation of such
indigenous knowledge is very important before they are being lost forever from the community.
Ethno-medicine, Ralte, Traditional knowledge, Mizoram, Hilly tribe
Health is like a precious jewel that makes life a wonderful adventure. Treating human health with indigenous traditional knowledge dates back age’s ago [1]. It is estimated that 70-80% of the people worldwide rely on indigenous herbal remedies for their primary healthcare [2].
The Ralte are hilly tribe living in Mizoram, Manipur and Myanmar. The word Ralte consists of two parts, viz, Ral means enemy and te indicates plurality. The Ralte people of the study area represent a well-organized tribe with unique dialect and identities. About 200 years ago they are found living mostly near Champhai in the Eastern part of Mizoram. The Ralte’s zealously maintained their individual identities and resisted absorption into the folds of Lushai (Mizo) tribes. They divided themselves into mainly 4 main clans namely Siakeng, Kawlni, Khelte and Lelhchhun clan [3]. Agriculture is the main occupation of the people.
The Ralte people are said and considered to be the noisiest people among the Mizo clan because of their high pitched tone. Almost the entire population in the rural areas (>95%) of Mizoram relies on herbal medicines and nearly 98% raw materials are harvested from wild plant resources [4].
Study area
The study area lies within Kolasib district in the northern most part of Mizoram and bordered by Aizawl district in the south and east and Mamit district in the west and Assam state in the north. The geographical area of Kolasib district is 1382.51 km. This is 6.56% of the state total geographical area (Figure 1). It is situated in between 23°5′to 24°35′N Latitude and 92°3′to 93°E Longitude [5].
The present study was conducted in Ralte dominated villages viz, North Chaltlang, Parsenchhip, North Bukpui, Thingthelh, North Hlimen, fewer numbers at Saiphai villages shown in Figure 2. The District is covered by Humid Sub-tropical Hill Zone (N. Hlimen, Parsenchhip, Bukpui, Thingthelh, N. Chaltlang villages) and Humid mild tropical zone (Saiphai village) [6].
Field observation
An extensive field work was conducted in these tribal’s dominated areas during 2013-2014. Prior informed consent was first obtained from the traditional healers. Random interviews of the herbalists, elderly men and women were done for documentation. The herbal healers or the knowledgeable person took the interviewers to the areas where they collect the plants and describe its uses. Plant specimens were photographed, collected, pressed and identified with the help of regional floras and manuals available [7-10]. The unidentified specimens are taken to Botanical Survey of India (BSI), Shillong for matching and identification. They are deposited as voucher specimen in the Herbarium of Mizoram University, Aizawl or in life forms in the botanical garden of Mizoram University, Aizawl.
From the 35 (26 female and 9 males) informants interviewed the important medicinal plants used by the tribal are, covering 106 plant species belonging to 96 genera and 57 families along with their uses are listed along with the collection number (ZO) are listed in Table 1. Most of the plants used for treatment are collected from the wild (73 plants; 68.86%). Habit wise analysis of the plants indicates that trees are highly used (33 spp.), herbs (28), climbers (13), shrubs (12) with Small tree (12) while epiphytes, succulents, canes and bamboo are less represented.

Table 1: Plants used by the Ralte tribes for treating different diseases
Of the 57 families reported Euphorbiaceae and Asteraceae have been found to be the most dominant with 8 species in used, followed by Zingiberaceae and Cucurbitaceae with four and five species respectively. Some of the common ailments those are cured by using herbs are fever, cough, dysentery, toothache, cuts and wounds etc. Usually one plant was used for treatment of a single ailment, like Adina cordifolia for typhoid. Used of the same species for more than one ailments were also common, like use of Callicarpa arborea for both hypertension and stomach ulcer. Depending on the type and severity of the disease they usually prefer external or internal applications, usually by decoction of the plant part, infusion, ash of the plant, paste which are directly taken alone or with sugar and honey. Leaves are highly utilized by the local people (29%), followed by bark (16%), aerial part of the plant (13%), fruits (8%), roots and juice (7%) whereas the rest like flowers, stem, latex or lac, seeds are less represented.
The Ralte traditional herbal healers and knowledgeable persons are co-operative, their hospitality and their response were noteworthy. They are among one of the trusted members of the community. In each village it is found that women have better knowledge about plants and their medicinal uses than men. Due to the road conditions and the distance of the villages from the hospital, the people mainly depend on plants and its resources for their first aid as medical facilities were not easily available. Shifting cultivation, smuggling of medicinal plants and overexploitation are also the major threats to the medicinal plants. However there is a concern that these knowledge are disappearing from the community. Therefore, the need for documentation of such indigenous knowledge is very important before they are being lost forever from the community.
The authors are extremely grateful to the Ralte community people for their co-operation, guidance and their hospitality during the course of the study. The financial support given to Miss Zorinpuii Khiangte through UGC Maulana Azad National Fellowship for Minority Students is also deeply acknowledged.
