How Our Ancestors Used Salvia

Salvia Viridis has been grown in England since the 16th Century and was once illustrated by an English herbalist named John Gerard in his 1,484-page illustrated book Herball, published in 1597. Here he wrote of the beneficial medicinal applications the herb had on the human body…

On Women’s Reproductive health and prenatal care– ‘grippa and likewise Aetius have called it the Holy-Herb; because women with child if they be like to come before their time, and are troubled with abortments, do eat thereof to their great good; for it closeth the matrix, and maketh them fruitful, it retaineth the birth, and giveth it life, and if the woman about the fourth day of her going abroad after her childing, shall drink nine ounces of the juice of Sage with a little salt, and then use the company of her husband, she shall without doubt conceive and bring forth store of children, which are the blessing of God. Thus far Agrippa’.

For Brain Health and good Memory-Sage is singular good for the head and brain; it quickeneth the senses and memory, strengtheneth the sinews, restoreth health to those that have the palsy upon a moist cause, takes away shaking or trembling of the members; and being put up into the nostrils, it draweth thin phlegm out of the head’.

For Snake bites and Pain-‘It is likewise commended against the spitting of blood, the cough, and pains of the sides, and bitings of serpents’.

Heartburn and Sinuses-‘The juice of Sage drunk with honey is good for those that spit and vomit blood, and stoppeth the flux thereof incontinently, expelleth wind, drieth the dropsy, helpeth the palsy, strengtheneth the sinews, and cleanseth the blood’.

Oral Care and Personal Grooming– ‘The leaves sodden in water, with Woodbine leaves, Plantain, Rosemary, honey, alum, and some white wine, make an excellent water to wash the secret parts of man or woman, and for cankers or other soreness in the mouth, especially if you boil in the same a fair bright shining sea-coal, which maketh it of greater efficacy’.

For Stitches and Chest Infections – The leaves of Sage put into a wooden dish, wherein is put very quick coals, with some ashes in the bottom of the dish to keep the same from burning, and a little vinegar sprinkled upon the leaves lying upon the coals, and so wrapped in a linen cloath, and holden very hot unto the side of those that are troubled with a grievous stitch, taketh away the pain presently: The same helpeth greatly the extremity of the pleurisy.

  • Sow indoors from March to May

  • Once the seedlings are large enough to handle, prick out and pot on into individual modules or pots
  • Plant out in a sunny or part shade spot around 20 cm apart once all risk of frost has passed. * Be sure to harden off indoor raised plants before planting out

What Does Hardening Off Mean?
Plants raised indoors or in a greenhouse environment, need to be acclimatised to cooler temperatures and increased air movement for about two to three weeks before they are planted outdoors permanently. This is a ‘toughening up’ practice to prepare the plants for their new environment.

How to Harden Off
Place your plants out for a couple of hours in a shady part of the garden. The next day, leave them out again for two hours, but this time allow the plants an hour of direct sunshine in the morning. Gradually continue to increase the length of time the plants are in direct sunshine over the course of roughly two weeks.
