A viral TikTok trend encouraging women to add menstrual blood to moon water has become linked to a new theory about the mysterious Voynich Manuscript, with 'WitchTok' creators claiming the centuries-old book may contain a secret record of women's reproductive knowledge.
The trend involves collecting menstrual blood in water left under moonlight, with some creators claiming that the mixture can be used in rituals or to encourage plant growth. One viral discussion then drew comparisons between plants produced in these experiments and the strange botanical illustrations found throughout the Voynich Manuscript.
