Huernia hystrix, the porcupine huernia, is a species of flowering plant in the family Apocynaceae, native to southeastern Africa.[1][2] A succulent, it has gained the Royal Horticultural Society's Award of Garden Merit.[3]
H. hystrix is extensively sold in Zulu markets throughout South Africa for its supposed medicinal and protective magical properties,[4] and in Eswatini as an alleged aphrodisiac.[5] Extracts from its stem and leaves may contain chemicals with anti-inflammatory properties,[6] It has been proposed as a treatment for people suffering from HIV/AIDS.[7]
It is highly drought-tolerant and grows well in pots, and so is a good species for ornamental xeriscaping.[8] Destructive whole-plant harvesting has led to concerns about its survival.[9] Researchers at University of KwaZulu-Natal Botanical Garden have discovered multiple shoots can be propagated from a single explant by treatment with Murashige and Skoog medium + 1-Naphthaleneacetic acid + 6-Benzylaminopurine with 95% survival rates.[6]
