According to an ancient legend, the night of Saint John is the night in which the Sun stops to marry the Moon, the last night of the summer solstice (from the Latin sol-stĭtĭum, composed of sōl, "Sun", and sistĕre, “to stop”), it is the shortest night of the year, the light wins over the darkness.
That night you have to collect new herbs which only that night are enriched with virtues that make them magical.
“The sun reaches its highest point on June 23rd:
St. John's night is the time when
the planets and zodiac signs
they help to load the stones and herbs with virtues.
It's a magical night,
the night of the impossible, the night of wonders.”

The collected herbs, placed in a basin filled with water, left in the moonlight, have the power to increase beauty and keep adversity away.
Like St. John's Wort to guarantee peaceful sleep, Mint which ensures long life; Rosemary keeps witches and calamities away; Lavender that protects the whole family.
In the St. John's Herbs essence, from the "Le vie aromatiche" collection by Wally 1925, St. John's Wort, Mint, Rosemary and Lavender are mixed, accompanied and flavored with Orange, Begamotto, Thyme, Marjoram, Jasmine... to give fresh, spicy and flowered.
This is how the magic of the night of the solstice is passed down, with the Herbs of St. John to protect our homes.
