Do madhiy and wadiy come out of a woman?

The water (secretions) of a woman fall into the same categories as water secreted by a man; so maniy [semen; fluid emitted at the point of climax], madhiy [a fluid which is usually secreted as a result of sexual excitement] and wadiy [a thick, white fluid which may come after urination or due to other reasons such as illness] are all secreted by her. If madhiy comes out of her, she has to wash her private parts, and if wadiy comes out of her, it is subject to the same rulings as urine and she has to wash it away.

Fatawa al-Lajnah al-Daa’imah.

Fatawa al-‘Ulamaa’ fi ‘Ushrat al-Nisaa’, p. 37

Shaykh al-Fawzaan answered a question concerning the ruling on the secretions which come out of women and whether they are considered to be naajis. He said: the secretions which come out of a woman’s vagina are naajis (impure); they break her wudu, and whatever parts of the body or clothing they touch become naajis, so the woman has to do istinjaa’ and wash them away, then do wudu if she wants to pray. She must also wash the places on her body or clothing that are touched by them. 

If any secretions come out of a woman because of her husband’s kisses or foreplay, she does not have to do ghusl unless that is maniy which flows at the time of climax. 

Fatawa al-Mar’ah al-Muslimah, 1/222 

Since it is clear that madhiy, wadiy and urine are all naajis, it is not permissible to swallow them because swallowing impure substances is haram. 

Al-Shaafa'i said: it is not permissible to drink or eat impure substances. (al-Umm, vol. 7, p. 221) 

Ibn Qudamah said in al-Mughni: Drinking impure substances is haram. (vol. 1, p. 378) 

Al-Dasooqi said: If a person eats of drinks something impure, he must force himself to vomit… (Haashiyat al-Dasooqi, vol. 1, p. 69) 

With regard to maniy, it is taahir (pure), but the idea of swallowing it is repulsive to people of sound mind and upright nature. It is not permitted to eat, drink or swallow revolting things.

And Allah knows best.
