Gemmotherapy is a branch of phytotherapy, developed in the 1960s, which uses plant buds and young shoots. Developed by Dr Pol Henry, a Belgian physician and phytotherapist, gemmotherapy is based on the totipotency of embryonic plant cells, that is, their ability to differentiate and give rise to all parts of the plant (branches, leaves, flowers, fruits, etc.), as well as all of its functional tissues and organs.
For this reason, buds exhibit a particularly high concentration of primary and secondary metabolites. Primary metabolites are essential for plant development: nucleic acids, amino acids, sugars, minerals, as well as phytohormones (auxins, cytokinins, gibberellins, abscisic acid), which are responsible for the initiation and regulation of plant and tree growth.
Secondary metabolites (polyphenols, flavonoids, tannins, phenolic acids, iridoids, etc.) are involved in the plant’s defense mechanisms, adaptation, and protection. It is this richness in metabolites that gives gemmotherapy its particular value.
The concentrated GemmoPure® macerates from Laboratoire THERASCIENCE are produced according to the traditional method of Dr Pol Henry, by macerating the buds in a mixture of three complementary solvents, in equal parts: 1/3 water, 1/3 ORGANIC alcohol and 1/3 ORGANIC glycerin, for a minimum duration of 21 days, followed by a filtration step. This combination of solvents allows for an optimal and complete extraction of the active molecules from the buds.
Why choose GEMMOPURE® Rosemary BIO?
GEMMOPURE® Rosemary BIO is a high-quality macerate made from fresh young shoots of rosemary, sourced from organic farming, hand-harvested in France in an eco-responsible manner, and placed into maceration directly at the harvesting site, without prior freezing. The maceration is carried out by triple extraction (water, alcohol, and glycerine) for 21 days, according to the traditional method.
GEMMOPURE® Rosemary BIO is standardized at 5% in dry young shoot equivalent, ensuring a consistent level of active compounds with each intake. Each daily dose of 30 drops provides the equivalent of 900 mg of concentrated macerate, corresponding to 126 mg of fresh young shoots.
As part of a rigorous quality approach, GEMMOPURE® Rosemary BIO is formulated without colouring, without ingredients based on lactose or gluten, and is suitable for vegans. It is manufactured and packaged in France, in compliance with Good Manufacturing Practices (GMP) and HACCP standards. GEMMOPURE® Rosemary BIO is guaranteed Clean Label® and High Quality Process®, highlighting the rigorous selection of plants, optimal microbiological quality, and the use of titrated and standardized macerates, for scientifically controlled quality.
What does science say?
Rosemary has been the subject of scientific research, and its biological mode of action is documented in the health literature.
However, to date, European legislation has not validated any health claims for rosemary.
Although no specific benefit is officially recognized, rosemary is attracting increasing interest and opens promising perspectives that deserve to be explored.
The + of GEMMOPURE® Rosemary BIO

Benefits of rosemary in gemmotherapy
The rosemary (Rosmarinus officinalis L.) is an emblematic shrub of the Mediterranean basin that grows on dry, sunny, and calcareous soils. Meaning “dew of the sea,” rosemary is valued for its characteristic fragrance. Rooted in Mediterranean culture, rosemary has been used since Antiquity in culinary and aromatic traditions. In ancient Greece, students wore rosemary crowns to stimulate memory.
In gemmotherapy, it is the young shoots of rosemary that are used. Harvested at an early stage of development, they concentrate a high density of natural compounds. Their extraction relies on a gentle process aimed at preserving the integrity of the young shoots and the diversity of their molecules.
The young shoots of rosemary are part of a holistic approach, respectful of the body’s natural balance.
GEMMOPURE® Concentrated Macerate
The concentration of a young shoot macerate is an essential criterion to ensure its optimal effectiveness. It is indeed important to know the quantity of fresh young shoots used and their equivalent in dry young shoots, in order to evaluate the real richness of the extract. This is achieved thanks to a triple extraction (water, glycerine, alcohol) performed according to the traditional method.
GEMMOPURE® Rosemary BIO provides 900 mg of concentrated macerate of Rosemary BIO young shoots, corresponding to 126 mg of fresh young shoots, standardized and equivalent to 45 mg of dry young shoots per 30 drops. This balanced concentration ensures an optimal content of active molecules and reflects the quality of freshly harvested young shoots.
Thanks to the exceptional process, GEMMOPURE® guarantees a precise and consistent dosage, ensuring effectiveness and reliability in gemmotherapy.
Harvesting and quality
The rosemary young shoots used come from organic farming and are hand-harvested in France with the utmost care to preserve their integrity. They are immediately placed into maceration at the harvesting site for 21 days, according to the traditional method, thus ensuring a complete extraction faithful to the principles of gemmotherapy.
Unlike certain processes that use frozen young shoots, which may alter the quality and reduce the bioavailability of active compounds, the GEMMOPURE® concentrated macerates use fresh young shoots, which allows all their fragile and volatile compounds to be preserved. This approach ensures optimal effectiveness.
Thanks to this expertise, each GEMMOPURE® macerate concentrates all the natural richness of rosemary young shoots to offer an authentic, pure product that meets the highest quality standards.
Enhanced naturalness
Committed to a natural approach, GEMMOPURE® Rosemary BIO complies with Clean Label® standards and benefits from the High Quality Process® label.
Each macerate is formulated to guarantee a composition faithful to the naturalness of the fresh young shoots.
The formula is rigorously designed to meet the most demanding expectations: without coloring, without flavoring, without sweetener, without added sugar, and not tested on animals.
Our GEMMOPURE® formulas are manufactured in France. They meet the strictest dietary requirements: without ingredients of animal origin, without gluten- or lactose-based ingredients, thus suitable for vegans.
