اللَّهُمَّ ارْزُقْنَا مِن فَضْلِكَ ولا تَحْرِمْنَا رِزْقَكَ وبَارِكَ لنَا فيمَا رَزَقتَنَا، واجْعَلْ غِنآئنَا في أنفُسِنَا، واجْعَلْ رَغْبَتَنَا فيمَا عِندَكَ

Thyme ~ صعتر

روى أبو نعيم في الطب عن أبان بن صالح عن أنس - رضي الله تعالى عنه - أن رسول الله - صلى الله عليه وسلم - قال: -  (بخروا بيوتكم بالشيح والمر والصعتر) كنز العمال    - حديث ضعيف 28316

Narrated by Abu Nuaim on the authority of Abban Bin Saleh Bin Anas radi Allaho Anh, that Prophet Muhammad Sallallaho Alaihe Wasallam said : "Fumigate your houses with Mugwort, Myrrh & Thyme". (Kanz-ul-Ummal) (Weak Hadith).

Apart from fumigation, all of the above 3 are edible as well & the combined army of these three will kill the germs, bacteria & other microbes / organisms in intestines Insha'Allah. Thyme (Za'atar) is another miracle of my Allah's creations, it is common among Arabs to eat Thyme blended with sesame seeds & salt, but it is un-known to the rest of Muslim world. It is high in Vitamin "K", Iron & Manganese. The volatile oil components of thyme have also been shown to have antimicrobial activity against a host of different bacteria and fungi. Staphalococcus aureus, Bacillus subtilis, Escherichia coli and Shigella sonnei are a few of the species against which Thyme has been shown to have antibacterial activity. For thousands of years, herbs and spices have been used to help preserve foods and protect them from microbial contamination, now research shows that both thyme and basil contain constituents that can both prevent contamination and decontaminate previously contaminated foods.

Imam Zahabi wrote about Thyme : Sa'tar (Thyme) is hot & dry in the third degree, it removes gas, reduces bloating, helps to digest heavy foods, cleanses the skin's color, opens urine & menstruation, very good for coldness in stomach & liver, increases the sex drive, fixes Colds / Flu when inhaled, & kills the intestinal worms. Ibn Al Jauzi narrated that Prophet Muhammad Sallallaho Alaihe Wasallam said "Fumigate your houses with Thyme & Frankincense (Lubaan)". 

Eating Thyme (Za'tar Farsi) is favorite among Arabs, but they take it with heavy salt (usually the Fatair ~ pastry that are made with Thyme, Salt & Sesame dipped in Olive Oil). Thyme is the least common among Indo-Pak community. Dried Thyme is also available in RAW form, it should be cleaned properly before grinding, dust & sticks (branches) should be removed; we only need the dried leaves. Thyme will be the best for children / adults who suffer with intestinal worms.
