From the pharmacopoeias of the past to the medicines of the future: a journey into the little-known world of traditional medicine, which is currently enjoying a resurgence of interest. Welcome to the Montpellier apothecary.

Antique jars, majestic cabinets, old glass panes reflecting the gazes of curious onlookers… Here, in their natural form or as dried stems, lie our grandmothers’ remedies, jumbled together with traditional ingredients from Africa, Asia, and the Americas: from the purifying dandelions of our scrublands to precious Chinese teas, including medicinal plants from Réunion, vipers in bottles and other dried centipedes, or even ambergris from distant seas…

Living Collections

This astonishing treasure trove is hidden at the end of an unassuming corridor in the Montpellier School of Pharmacy. Yves Pélissier holds the keys. When he opens the doors to Montpellier’s venerable apothecary —heir to the very first apothecary established in 1588—visitors are transported to another world.
In its heyday, there were up to 45,000 samples here, recalls the man who, along with Chantal Marion, fought to preserve this place threatened by flooding, dust, and neglect. In 2009, thanks to their efforts, the Montpellier apothecary was designated a historic monument. Today it houses nearly 10,000 samples of “medicinal substances”: minerals, plants, and animal substances. These collections have been built up over the centuries through travel and exchanges with the entire world.
A museum? Not exactly. Because this collection remains a living entity. It grows every day through donations and bequests. And through research as well: the herbarium has become a very active center for education and research. Since 2002, it has inspired more than 75 theses. As for the university degree in phytotherapy recently created by Yves Pélissier, it’s in high demand: 157 applications this year for 33 spots…

Ethnopharmacology

A growing interest that reflects the fascination with ethnopharmacologytoday: this science that explores traditional knowledge and what it has to teach us. Knowledge that is complex, to say the least. For a plant is a veritable cocktail of chemical compounds, varying according to numerous factors: the season, the soil, sunlight exposure…“Our ancestors knew very precise harvesting times and locations . Today, we often lack reliable information, as well as properly trained practitioners. There is therefore a real risk, particularly when it comes to self-medication via the Internet.”

This warning applies particularly to aromatherapy, a branch of herbal medicine based on the use of essential oils. For plants are not harmless. Just as their benefits have been known since time immemorial, so too has their toxicity.“They should only be prescribed according to best practices and by recognized specialists. There is nothing harmless, for example, about a simple eucalyptus oil: in excessive doses, it can be toxic,” warns Yves Pélissier, professor of pharmacognosy, phytotherapy, and aromatherapy.
With the advent of chemistry in the^19th century, allopathic medicine gradually supplanted traditional medicines. Today, these traditional practices are making a major comeback. Their main appeal?“They don’t just treat symptoms. They offer a ‘holistic’ approach—that is, a comprehensive one.” In other words,“they have the merit of focusing on your well-being, offering a harmonious balance that doesn’t neglect any aspect—psychology in particular. Acupuncture, massage, energy, herbs: Chinese medicine, for example, incorporates all of this!”

Learning from the past

Yves Pélissier does not, however, pit conventional medicine against traditional medicine. Instead, he speaks of “complementary approaches.”“Allopathy—of which herbal medicine is, incidentally, an integral part—has proven its worth. Traditional therapies also have their place. When administered professionally and under medical supervision, they can be recommended in primary healthcare, to support patients’ well-being, or to mitigate the side effects of certain treatments.”
It is worth noting that in emerging countries,the WHO now recommends the use of“improved traditional medicines.”Inexpensive and effective, these derivatives of traditional pharmacopoeia are ideally suited to addressing basic health issues—fever, hemorrhage, or dysentery. Yet we must still ensure the preservation of ancestral knowledge that is in danger of disappearing…
A neglect that does not spare our industrialized nations. Fortunately, research is now taking over from tradition. A repository for ancient pharmacopoeias and a resource center for educators, the Montpellier Herbarium is also a laboratory that connects scientists from around the world.“Researchers are on the lookout. These days, many plants from traditional pharmacopoeias are the subject of scientific studies to confirm their therapeutic applications.” After a lengthy process, these plants—previously unknown to modern science—may be included in the highly official European Pharmacopoeia. Inclusion in the pharmacopoeia signifies recognition of their medicinal properties: a necessary condition for them to one day be prescribed by your doctor.
Far from being doomed to oblivion in our grandmothers’ cupboards, plants represent a source of hope for the treatments of tomorrow, and the Montpellier Herbarium a fabulous playground for researchers.“In the face of new technologies, the future of herbal medicine is not bleak,” concludes Yves Pélissier. “We have things to learn from the past— provided we apply today’s scientific methods to this ancestral knowledge.”
