Recent research indicates that African elephants in Kenya may be engaging in self-medication, utilizing specific plants and minerals for medicinal purposes. A study published in the journal *Scientific Reports*, on 24 September, highlights how these elephants, particularly in the Mount Elgon region, seek out certain flora when they are unwell.

The investigation into this behaviour was fuelled by interviews with members of the Sabaot Indigenous community, comprising wildlife scouts, local guides, elders, and a retired ranger. These individuals have dedicated over two decades to observing the elephants in their natural habitat. They reported that the elephants consume a total of 35 plant species and four varieties of soil or minerals, with a remarkable 87% of these resources also being recognised for their medicinal applications in traditional human medicine.
Among the plants identified, eight were noted for their targeted use by sick elephants, suggesting a sophisticated understanding of their medicinal properties. The local experts provided compelling evidence of intentional foraging, indicating that the elephants are actively seeking out these plants to aid their health, rather than consuming them by chance.
One particularly fascinating observation involved mother elephants caring for their calves. The wildlife observers documented instances where mothers would chew specific roots and leaves, then mix them with their milk to feed their young. This behaviour was described by the community as a form of “immunization” for the calves. Additionally, the elephants were noted to use certain species belonging to the genus *Dombeya* to assist with digestion and to enhance the appetites of their offspring.
The study’s co-author, Elodie Freymann of Brown University, remarked on the potential implications of habitat loss for these elephants. She emphasised that the earth is home to countless organisms capable of producing medicines, calling for the need to safeguard these environments. “These plants are medicine factories that exist all around us,” she stated, underscoring the peril that deforestation poses to both wildlife and human health.
Mount Elgon’s elephants are already known for their unique behaviour of “mining” caves to obtain mineral-rich salt and clay. The findings from this research elucidate that the elephants’ quest for medicinal resources extends far beyond these caves, further enriching our understanding of their behavioural ecology.
However, the conclusions drawn from this study have not been universally accepted within the scientific community. Michael Huffman, a primatologist at Nagasaki University and an expert in animal behaviour, expressed caution regarding the findings. While he acknowledged the intriguing nature of the observations related to calf feeding, he advocated for more robust evidence before confirming that elephants provide their young with specific medical treatments. The researchers themselves concurred that more extensive pharmacological testing and long-term observational studies are essential next steps in this exploration.
Despite ongoing debates concerning the implications of these findings, the research contributes to the expanding field of zoopharmacognosy, which examines self-medication across various animal species. Previous studies have demonstrated similar behaviours in animals ranging from primates to insects, highlighting the evolutionary advantages that such practices may confer.
Freymann concluded that protecting the forests is essential not only for the welfare of the elephants but also for the potential future discoveries of natural products that could benefit human health. “It’s a win-win for us to protect these forests and keep those natural pharmacies around,” she stated, reinforcing the intrinsic connection between wildlife conservation and human medicinal advancement.
As the challenges of habitat loss continue to mount, the knowledge gained from these observations underscores the urgent need for conservation measures that ensure both biodiversity and the survival of these intelligent, resilient creatures. This study serves as a poignant reminder of the intricate relationships between species and their ecosystems, and the wisdom that can be found in traditional knowledge surrounding the natural world.
