Prophet's Guidance on Treating Constipation

At-Tirmidhi and Ibn Majah narrated that the Prophet (peace be upon him) asked Asma' Bint 'Umais (may Allaah be pleased with her):

"How do you deal with constipation?" She said, "By using Shubrum (euphorb piteous)." The Prophet (peace be upon him) said, "(It is) hot and to strong laxative." She then said, "I also use Senna," and the Prophet (peace be upon him) replied, "If there is a cure that prevents death, it would be Senna."

Further, Ibn Majah narrated that Abdullah ibn Umm Haram (may Allaah be pleased with him) said that he heard the Prophet (peace be upon him) saying:

"Use Senna and Sanoot (cumin), because they cure every disease, except Saam." He was asked, "What is Saam?" He said, 'Death.'"

The Prophet (peace be upon him) asked the women about what she uses to treat constipation, meaning what cure she uses to help soften the stool, so that the body is able to get rid of its harmful waste.

Senna is a plant that grows in Al-Hijaz (Western Arabia) and the best kind of it grows in Makkah.

Senna is hot and dry in first degree and it is a good mild medication that does not cause any side effects.
Senna helps against bile and black bile ailments and strengthens the heart, which is another good quality that this medication contains.
Senna is useful against melancholic obsession and corporal incisions, relaxes the muscles and improves the hair.
Senna also helps against lice, headache, mange, pustules, rashes and epilepsy. It is better to cook the Senna whole and drink three measures of its soup than cooking it crushed. Also, it is better to cook the Senna mixed with violet flowers and red raisins, after removing the seeds.

Senna and fumitory help extract mature humors (bodily wastes) and helps against leprosy and rashes, when one takes four to seven measures of each remedy
