FAQs about Manjakani

Is Manjakani effective for Vaginal Tightening?

However, Manjakani is not used for this purpose traditionally. In traditional medicine, it is used for reducing the watery discharge and mucoidal secretions that occur due to vaginal infections or leucorrhoea. It has a similar action as Triphala does. Washing genitals with Triphala water are advisable for disinfecting. Manjakani decoction is also used in a similar way for getting same benefits. So, it acts on outermost layers, temporarily contracts the cells, reduces watery discharge and mucoidal secretions, eliminates infections due to antimicrobial action, and produces dryness.

Manjakani has an astringent action due to its high tannin content. It can temporarily help to tighten outermost layers of mucosa due to its astringent action that induces temporary cell contraction, which make you feel temporary tightening. These effects are not permanent. It should not be used if you have any of the following symptoms:

  • Vaginal dryness
  • Vaginal Irritation due to dryness
