Where does sage grow?

Sage grows mainly in relatively warm countries (eg the Mediterranean region).
Much of the world’s supply of sage derives from wild harvesting (in a native environment) in the mountains of Croatia, Montenegro and Albania. It is a perennial plant, that is, it can live for several years. Sage reaches a height of between 20 and 70 cm, some sources speak of up to 1 m. Over time, sage can form small bushes because of its increasingly woody stems.

When to harvest sage?

Sage leaves are harvested in summer.

Grow it yourself
Sage does very well in pots and large planters.


– To treat excessive sweating , sage can be very effective, as it has the advantage, compared to other synthetic drugs (aluminum salts, anticholinergics), of having very few important side effects. That said, a special edition of the French journal Science & Vie on medicinal plants published in July 2020 estimated that the effect of sage (or rather sage according to further studies: Salvia officinalis – the sage in this dossier, Salvia sclarea and Salvia lavandulifolia ) against excessive sweating has yet to be demonstrated, due to the lack of serious published scientific studies.

– To combat colds and sore throats , sage can be a good natural supplement, as it can speed up healing thanks to its essential oil form. Several scientific studies have proven its efficiency against sore throats .

– Sage belongs to the Provencal herbs which include: rosemary , thyme , hyssop , lavender, fennel , etc. These plants grow in dry and hot conditions during the summer, as is the case in the south of France, where the city of Provence is located.

– As sage is close to rosemary in botanical terms, these 2 plants are often used together, especially in cooking.
