MPNS has built upon Kew’s existing plant name resources to create an authoritative database of medicinal plants and their names. Up to date taxonomy is linked to pharmaceutical, drug, common and scientific names as they are used in the relevant literature and legislation. The MPNS Resource currently covers approximately 25,000 species, corresponding to 32,600 unique scientific names used in the medicinal plant literature. It links these to 101,000 non-scientific names and to over 250,000 scientific names (synonyms) from Kew’s taxonomic resources drawn from the botanical and wider literature. The inclusion of non-scientific names (trade, pharmaceutical and common names in many languages) makes Kew’s taxonomic information more accessible and relevant to a wider audience.
This Resource enables us to offer a range of services enabling effective communication about medicinal plants in health, regulation and research. The data in this Resource is publicly available to search via our portal.
We also offer services tailored to the specific needs of different organisations and users including:
Please visit our services page for a list of services we provide, or contact us to discover how this could benefit your organisation.
We are continually updating the data contained in the Resource, improving coverage from relevant literature and ensuring the currency of the taxonomic judgements and accuracy of the information provided.
The MPNS Resource is built by collecting plant names from medicinal plant literature, this includes:
Our selection of references has been guided by three main aims:
A list of all references indexed in the Resource can be viewed on our references page. We are still adding data to the Resource, so please contact us if you know of additional references which you feel should be included.
MPNS links the non-scientific names from these references to Kew’s existing taxonomic databases via the associated scientific name. We have retained the scientific name used in a medicinal plant reference precisely as it was published there (including misspellings) to enable searches to be made using names that people are familiar with, and to allow comparison with the same name as published in botanical literature. This matching is usually completed automatically, but occasionally a judgement must be made as to which name from our taxonomic resources is the one intended by the reference in question. Matching takes place against the following taxonomic resources:
Detail on the relative merits of these taxonomic resources can be found on our FAQs page.
Non-scientific names are divided into pharmaceutical names and ‘other’ names. Pharmaceutical names are those used by pharmacopoeias for an individual drug (which may include more than one plant species) and are Latinized which means that they are often confused with scientific plant names. Ordinarily only names clearly identified as being pharmaceutical names in the original publication will be marked as pharmaceutical in the MPNS Resource, for example you may find some pharmaceutical names marked as ‘other’.
For most references we have collated information on which part of a plant is used. Information on how that plant part is prepared and traded, or whether a particular fraction is used (for example oil) is included in the MPNS portal under the heading: Trade forms.
MPNS V 7.0 is based on our coverage of 143 medicinal plant references. This includes 5 new references in version 7.0 which are of particular significance in trade and regulation. These are:
In addition, a further 13 new references have been added in version 7.0 to improve our regional coverage globally, including specific references relating to the following countries: Australia, Brazil, China, Fiji, Iran, Israel, Iraq, Sri Lanka and the Unites States. A number of Kew datasets including information on medicinal plants and which contributed towards both the 2016 and 2017 State of the World's Plants Useful Plants analyses have also been added.
V 7.0 includes 26,383 taxa: approximately 8,000 more taxa than were included in the previous version. These new taxa are mostly species although some are subspecies or varieties.
V 7.0 includes 26,383 taxa that belong to 382 families.
The taxonomic judgements for these taxa are of variable reliability depending on the level of taxonomic scrutiny that has been applied to each.
MPNS V 7.0 contains:
85,055 scientific name records from medicinal plant literature of which 32,629 are unique.
139,816 non-scientific name records for 100,907 unique non-scientific names including:
MPNS V 7.0 contains:
283,928 scientific names, of which 32,629 are derived from scientific names as published in medicinal plant references and 251,299 derive solely from Kew’s databases (scientific synonyms).
Taxonomic sources: Based on Kew’s taxonomic resources.
