Guide for collection and preparation

Collection and drying

You can harvest rosemary throughout the year, but it’s best to do so during the plant’s main growth phase, which occurs during the spring and summer. In this way, you ensure the possibility of finding tender stems, which contain a higher concentration of the active substances of rosemary. 

Rosemary blooms twice a year, in spring and autumn. If you want to obtain rosemary essence, it is the ideal time to collect it. In these cases, it is usually dried immediately to minimize the loss of aroma. If taken as an infusion, the flowers also provide a greater flavor. 

Popular knowledge says that the moon plays an important role in determining the ideal time to collect plants. The full moon makes the stems accumulate more sap and, therefore, improves their properties. The new moon, on the other hand, causes the plant fluids to concentrate in the roots.


Rosemary infusion is very aromatic and quite strong. The plant’s tannins give it a bitter taste that may not be appreciated by all palates. 


If you’re using dried rosemary, measure out about a teaspoon per cup (about 5 grams). You can also use fresh rosemary, but keep in mind that it adds more flavor, use a few sprigs.

Water temperature

Use very hot water, bring it to a boil and pour it into a cup next to the herb.


Let the infusion rest for at least 5 minutes.

Remember that there are other variants of preparations that take advantage of the health properties of rosemary, including rosemary oil, which is excellent for relaxing massages, or rosemary alcohol, good for effective rubs against colds.

The rosemary plant

Rosemary is another of those totally common plants in the Spanish geography, accustomed to heat and water scarcity, known by all and appreciated for its uses.

Rosemary is a shrub that is part of the labiatae family, which groups together some plants such as mint, basil, oregano or thyme, all of which are commonly used in Mediterranean cuisine for their aromatic properties. Many of the family have also been used since time immemorial for their medicinal properties.

Rosemary grows near the sea and in low mountain areas, but it does not tolerate frost well. It is widespread throughout the Iberian Peninsula, except in some areas in the north such as Galicia and Euskadi. Rosemary is native to the Mediterranean basin, beyond southern Europe, it is also possible to find it in North Africa and also in other more remote parts, such as western Asia. 

The rosmarinus of its scientific name, rosmarinus officinalis, derives from the Greek and means aromatic bush.

History of its use

Rosemary has had a long relationship with the peoples that have populated areas near the Mediterranean Sea basin. Its aromatic, medicinal and gastronomic properties aroused the interest of the locals since ancient times. 

In ancient Egypt, rosemary was part of the secret formulations used to embalm bodies in their funeral rites.

Easy to grow, rosemary was introduced to northern Europe by Christian monks, who brought it to monastery gardens beyond the Alps. 

Charlemagne, for his part, issued an edict ordering a selection of plants to be cultivated in royal gardens throughout his empire. Among them was rosemary. 

Rosemary also came to enter the culture of the towns. Sometimes rosemary was used to make crowns for parties and celebrations. An example is the celebration of Almatrieb, in the Alps, an old ramadera festival in which decorations and crowns are made using rosemary. Today, in the UK, rosemary wreaths are made on November 11 to honor combatants from the two world wars.
