In this study, researchers from India, Nepal and Fiji explored and documented the diversity and population status of ethnomedicinal plants grown in home gardens and their medicinal uses. Their findings were published in the Journal of Ethnobiology and Ethnomedicine.
Not much is known about the ethnomedicinal plants commonly planted in home gardens in the foothill region of Eastern Himalaya.
Some of these plants are not easily accessible in the wild.
The researchers conducted their study in 150 home gardens in the Cooch Behar district of West Bengal from May 2017 to May 2018.
Besides collecting plant specimens, they conducted interviews with garden owners using structured questionnaires to document diversity, population size and medicinal uses of the ethnomedicinal plants.
The researchers counted a total of 260 plants being grown in home gardens, 53 of which have various ethnomedicinal applications.
The 53 plants (37.73 percent woody perennials) represented 35 different plant families and 45 different genera.
Cocos nucifera (coconut) dominated the list with the highest number of uses, followed by Hibiscus rosa-sinensis (shoeblack plant).
The leaves were the most used parts for ethnomedicinal applications (19 species), followed by the fruits (12 species), bark (nine species) and roots (seven species).
The researchers documented 20 different diseases treated with the identified plants.
In some cases, more than one plant was used to treat an ailment.
As many as 10 species were used to treat only stomach-related problems.
Other ailments like cough, cold and jaundice were treated using six and four different species, respectively.
Based on these findings, the researchers concluded that home gardens in the Eastern Himalayas are key in maintaining diversity and are great sources of natural medicines in rural areas. They recommend including these home gardens in mainstream conservation strategies in the country.
