Fakta Thibbun Nabawi: Habbatus Sauda, Madu, dan Minyak Zaitun
Saudaraku, tahukah kalian bahwa penyakit itu ada dua macam, penyakit hati dan penyakit jasmani? Kedua penyakit itu disebutkan dalam Al-Qur’an. Klasifikasi jenis penyakit ini mengandung hikmah ilahi dan kemukjizatan yang hanya bisa dicapai oleh kalangan medis di pertengahan abad ke-18. Sesungguhnya iman kepada Allah dan para Rasul, yaitu aqidah yang tertanam dalam hati, merupakan solusi pengobatan yang terpenting bagi hati, yakni bagi penyakit jiwa. Sedangkan untuk penyakit jasmani, kita bisa menengok metode pengobatan Nabi shallallahu ‘alaihi wa sallam.
Istilah Thibbun Nabawi dimunculkan oleh para dokter muslim sekitar abad ke-13 M untuk menunjukkan ilmu-ilmu kedokteran yang berada dalam bingkai keimanan pada Allah, sehingga terjaga dari kesyirikan, takhayul dan khurofat.
1. Habbatus Sauda’ atau Jinten Hitam atau Syuwainiz
Imam Bukhari meriwayatkan dari ‘Aisyah radhiyallahu ‘anha. bahwa ia pernah mendengar Nabi shallallahu ‘alaihi wa sallam bersabda yang artinya: “Sungguh dalam habbatus sauda’ itu terdapat penyembuh segala penyakit, kecuali as-sam.” Saya bertanya, “Apakah as-sam itu?” Beliau menjawab, “Kematian”. Habbatus sauda’ berkhasiat mengobati segala jenis penyakit dingin, bisa juga membantu kesembuhan berbagai penyakit panas karena faktor temporal. Biji habbatus sauda’ mengandung 40% minyak takasiri dan 1,4% minyak atsiri, 15 jenis asam amino, protein, Ca, Fe, Na dan K. kandungan aktifnya thymoquinone (TQ), dithymouinone (DTQ), thymohydroquimone (THQ) dan thymol (THY). Telah terbukti dari berbagai hasil penelitian ilmiah bahwa habbatus sauda’ mengaktifkan kekebalan spesifik/kekebalan didapat, karena ia meningkatkan kadar sel-sel T pembantu, sel-sel T penekan, dan sel-sel pembunuh alami. Beberapa resep penggunaan dan manfaat habbatus sauda’:
Ditumbuk, dibuat adonan dangan campuran madu, kemudian diminum setelah dicampur air panas, diminum rutin berhari-hari: menghancurkan batu ginjal dan batu kandung kencing, memperlancar air seni, haid dan ASI.
Diadon dengan air tepung basah atau tepung yang sudah dimasak, mampu mengeluarkan cacing dengan lebih kuat.
Minum minyaknya kira-kira sesendok dicampur air untuk menghilangkan sesak napas dan sejenisnya.
Dimasak dengan cuka dan dipakai berkumur-kumur untuk mengobati sakit gigi karena kedinginan.
Digunakan sebagai pembalut dicampur cuka untuk mengatasi jerawat dan kudis bernanah.
Ditumbuk halus, setiap hari dibalurkan ke luka gigitan anjing gila sebagian dua atau tiga kali oles, lalu dibersihkan dengan air.
Untuk konsumsi rutin menjaga kesehatan, sebaiknya dua sendok saja. Sebagian kalangan medis menyatakan bahwa terlalu banyak mengkonsumsinya bisa mematikan.
2. Madu atau ‘Asl
“Dari perut lebah itu keluar cairan dengan berbagai warna, di dalamnya terdapat kesembuhan bagi manusia.” (QS. An-Nahl: 69)
Beberapa hasil penelitian tentang madu:
a. Bakteri tidak mampu melawan madu
Dianjurkan memakai madu untuk mengobati luka bakar. Madu memiliki spesifikasi anti proses peradangan (inflammatory activity anti)
b. Madu kaya kandungan antioksidan
Antioksidan fenolat dalam madu memiliki daya aktif tinggi serta bisa meningkatkan perlawanan tubuh terhadap tekanan oksidasi (oxidative stress)
c. Madu dan kesehatan mulut
Bila digunakan untuk bersikat gigi bisa memutihkan dan menyehatkan gigi dan gusi, mengobati sariawan dan gangguan mulut lain.
d. Madu dan kulit kepala
Dengan menggunakan cairan madu berkadar 90% (madu dicampur air hangat) dua hari sekali di bagian-bagian yang terinfeksi di kepala dan wajah diurut pelan-pelan selama 2-3 menit, madu dapat membunuh kutu, menghilangkan ketombe, memanjangkan rambut, memperindah dan melembutkannya serta menyembuhkan penyakit kulit kepala.
e. Madu dan pengobatan kencing manis
Madu mampu menurunkan kadar glukosa darah penderita diabetes karena adanya unsure antioksidan yang menjadikan asimilasi gula lebih mudah di dalam darah sehingga kadar gula tersebut tidak terlihat tinggi. Madu nutrisi kaya vitamin B1, B5, dan C dimana para penderita diabetes sangat membutuhkan vitamin-vitamin ini. Sesendok kecil madu alami murni akan menambah cepat dan besar kandungan gula dalam darah, sehingga akan menstimulasi sel-sel pankreas untuk memproduksi insulin. Sebaiknya penderita diabetes melakukan analisis darah dahulu untuk menentukan takaran yang diperbolehkan untuknya di bawah pengawasan dokter.
f. Madu mencegah terjadinya radang usus besar (colitis), maag dan tukak lambung
Madu berperan baik melindungi kolon dari luka-luka yang biasa ditimbulkan oleh asam asetat dan membantu pengobatan infeksi lambung (maag). Pada kadar 20% madu mampu melemahkan bakteri pylori penyebab tukak lambung di piring percobaan.
g. Selain itu madu amat bergizi, melembutkan sistem alami tubuh, menghilangkan rasa obat yang tidak enak, membersihkan liver, memperlancar buang air kecil, cocok untuk mengobati batuk berdahak. Buah-buahan yang direndam dalam madu bisa bertahan sampai enam bulan.
Madu terbaik adalah yang paling jernih, putih dan tidak tajam serta yang paling manis. Madu yang diambil dari daerah gunung dan pepohonan liar memiliki keutamaan tersendiri daripada yang diambil dari sarang biasa, dan itu tergantung pada tempat para lebah berburu makanannya.
3. Minyak Zaitun
“Konsumsilah minyak zaitun dan gunakan sebagai minyak rambut, karena minyak zaitun dibuat dari pohon yang penuh berkah.” (HR. At-Tirmidzi dan Ibnu Majah).
Fungsi minyak zaitun:
Mengurangi kolesterol berbahaya tanpa mengurangi kandungan kolesterol yang bermanfaat.
Mengurangi risiko penyumbatan (trombosis) dan penebalan (ateriosklerosis) pembuluh darah.
Mengurangi pemakaian obat-obatan penurun tekanan darah tinggi.
Mengurangi serangan kanker.
Melindungi dari serangan kanker payudara. Sesendok makan minyak zaitun setiap hari mengurangi risiko kanker payudara sampai pada kadar 45%.
Menurunkan risiko kanker rahim sampai 26%.
Pengkonsumsian buah-buahan, sayuran, dan minyak zaitun memiliki peran penting dalam melindungi tubuh dari kanker kolon.
Penggunaan minyak zaitun sebagai krim kulit setelah berenang melindungi terjadinya kanker kulit (melanoma)
Berpengaruh positif melindungi tubuh dari kanker lambung dan mengurangi risiko tukak lambung.
Mengandung lemak terbaik yang seharusnya dikonsumsi manusia seperti yang terdapat dalam ASI.
Penggunaan sebagai minyak rambut mampu membunuh kutu dalam waktu beberapa jam saja.
Setiap penyakit itu ada obatnya, seperti hadits Rasulullah shallallahu ‘alaihi wa sallam yang artinya: “Tidaklah Allah menurunkan suatu penyakit, melainkan Dia menurunkan obatnya.” (HR. Bukhari dan Muslim) Setiap kali Allah menurunkan penyakit, Allah pasti menurunkan penyembuhnya. Hanya ada orang yang mengetahuinya dan ada yang tidak mengetahuinya. Jauh sebelum ilmu pengetahuan berkembang pesat, Nabi shallallahu ‘alaihi wa sallam sudah mengetahui dan menerapkan pengobatan yang terbukti kemanjurannya.

otis elevator
Kuala Lumpur, Malaysia
Petronas Twin Towers
Soaring 1,483 feet (452 meters) above the busy streets of Kuala Lumpur, the Petronas Twin Towers were until recently the tallest buildings in the world. The towers were completed in 1998. And, ever since, they have been an integral part of Malaysia’s national pride and a globally known icon. The twin skyscrapers, joined by a dramatic sky bridge at the 44th floor, are the headquarters of Malaysia’s national oil corporation.
Seventy-six Otis elevators (29 of them double-deck) carry passengers through the towers at a speed of 23 feet (7 meters) per second. The buildings also feature Otis escalators.
Installing the elevators, among the largest ever made by Otis, posed unique engineering challenges. Architect Cesar Pelli designed the buildings’ floor plans to form an eight-pointed star, a traditional Malaysian Islamic pattern.
With a small, narrow footprint, there wasn’t enough space in the building core for a conventional “side-by-side” elevator configuration. Instead, the elevators were “stacked” so they overlapped and required less space. To dissipate the electricity generated by the heavy elevators moving through long, narrow shafts, Otis also built in “resistor banks” that absorb energy.
The elevator installation also focused on passenger comfort. To reduce cab noise in the buildings’ narrow shafts, the elevators were shrouded with aerodynamic coverings.

The origins of cancer
The origins of cancer
By Datuk Dr IBRAHIM WAHID
We’re introducing a new column on cancer called Living with Cancer. It’s a monthly columBy the Malaysian Oncological Society (MOS) in collaboration with sanofi-aventis Malaysia. This week, we take a general look at cancer.
THE word cancer originated from the Greek word “karkinos”. In English, this term translates into “carcinos” or “carcinoma”.
Hippocrates was the man that gave cancer its name. Also known as the Father of Medicine, he was the first person to clearly describe the differences between benign (non-cancerous) and malignant (cancerous) tumors1.
Hippocrates first noticed that blood vessels surrounding a malignant tumour looked like the claws of a crab and therefore proceeded to name his observation “karkinos”, or crab in English.
Cancer is not a disease of modern civilisations. The earliest recorded history describing cancer was found between 3000 BC to 1500 BC1. Details of medical conditions consistent with modern descriptions of cancer were found amongst the inscriptions of two papyrus scrolls of Egypt, known as the “Edwin Smith” and “George Ebers” papyri1.
The burden of cancer
Today, cancer remains one of mankind’s most feared diseases. Approximately 10.9 million people around the world are diagnosed with cancer every year, with almost half of these (45%) coming from Asia2.
Up to 24.5 million people worldwide were estimated to have received a diagnosis of cancer in the last five years2.
And each year, an estimated 6.7 million people die as a result of cancer, representing 12% of total deaths that occur annually2.
Cancer is one of the major health problems in Malaysia. It is now one of the leading causes of death among medically certified deaths, with lung cancer being the most common of all cancer related deaths3.
The National Cancer Registry received close to 43,000 notifications of cancer from Malaysian residents in 20034. Cancer occurs at all ages. The median age for cancer diagnosis was 59 years old among Malaysian men and 53 years old among Malaysian women4.
The most common cancers found in men over 50 years old are cancers of the lung, colon, rectum, nasopharynx, prostate and stomach. In women over 50 years old, cancers of the breast, cervix, colon, uterus, lung and rectum were most common4.
The evolution of modern treatment
The understanding of cancer and its treatments have undergone tremendous evolution since the times of the pharaohs to what it is today.
Back in ancient Egyptian civilisations, magic and religion were very much part of daily lives. Gods and demons were believed to be the cause for many ailments.
Treatment for cancer therefore, often involved supernatural elements, and the first recourse often involved making appeals to a deity. Priests and magicians played important roles, alongside with physicians.
Inscriptions in papyrus scrolls detailed the use of ointments, enemas, caster oil, suppositories and poultices in fighting various forms of cancer, often in addition to supernatural elements.
Following the decline of Egypt, medical and scientific development began to take place in Greece and Rome. Then, Hippocrates, together with another physician named Galen, began to revolutionise the practice of medicine through the use of reason and logic, slowly removing it from the grips of superstitions and magic1.
Hippocrates and Galen believed that human diseases are natural physical processes and hypothesised that cancer was the result of an excess of black bile1.
The Renaissance period saw voyages of discoveries that brought a surge in knowledge and new learning. Up till this time, a variety of remedies were used in the form of arsenic-containing creams and pastes.
The invention of the microscope in the late 17th century added much needed momentum in the quest to understand cancer, enabling closer observations on how cancerous cells behave.
The discovery of the lymphatic system in the late 17th century brought an end to Galen’s “black bile” theory. The understanding and treatment of cancer began to take on a new path, and new theory suggests that it was the result of abnormalities in the lymph and lymphatic system1.
It was not until the 18th century that a modern era in the science of cancer began to emerge. Two French physicians, Jean Astruc and Bernard Peyrilhe, took the very first steps and conducted research that give birth to modern experimental oncology1.
Systematic experiments on cancer were performed, leading to oncology as a medical specialty.
With the discovery of anaesthesia in 1844, surgical procedures flourished and classical cancer operations such as mastectomy (surgical removal of the breast) began to develop, changing the treatment paradigm for cancer.
The 19th, 20th and 21st centuries marked tremendous leaps in research, discoveries and developments in cancer treatment as well as improved understanding of its etiology. It is also during these times that the development and use of chemical compounds (chemotherapy) to treat cancer began to play a central role, alongside radiation and surgery.
Cancer as we know it today is much more complicated than what early scientists hypothesised. It is a class of diseases in which a group of cells display traits of uncontrolled growth, invasion into and destruction of nearby tissues, and sometimes metastasis (spread to other locations in the body via the lymphatic system or blood)5.
Nearly all cancers arise from abnormalities of genetic materials within cells. These abnormalities may be caused by carcinogens (cancer-causing agents) such as tobacco smoke, radiation, certain chemicals or infectious agents5.
Cancer therapy in the modern era
The discovery of various chemical agents during World War I and II kick-started the use of chemicals in fighting cancer.
During World War II, nitrogen mustard was used as ammunition for chemical warfare. Soldiers exposed to this gas were found to have abnormally low counts of white blood cells. Nitrogen mustard was then thought to have an effect on rapidly growing white blood cells.
Subsequent administration of it to a number of patients with lymphoma proved to be effective, albeit only temporarily.
This discovery spearheaded research into the use of chemical compounds for cancer treatment. Up to the 1980s, only a few chemical compounds were discovered and their use caused various toxicities.
However, since the 1990s, newer, more effective and safer chemotherapy compounds were discovered and have been in use for the treatment of cancer until this present day.
Stage IV colorectal cancer is one good example to illustrate how treatment advancements have extended the survival of patients.
Before the 1960s, a patient diagnosed with stage IV colorectal cancer can only hope to survive between four to six months without any use of chemotherapy6. With the discovery of 5-fluorouracil (a chemotherapy agent) in the 1960s, survival was extended to 12-15 months6, making it the only chemotherapy treatment for the next 30 years.
During the 1990s, the discovery of newer chemotherapy compounds such as oxaliplatin and irinotecan changed the treatment paradigm for colorectal cancer. The use of either of these two agents in combination with 5-fluorouracil further pushed up survival to around the range of 16-17 months6.
Therefore, combination therapy of oxaliplatin or irinotecan with 5-fluorouracil became the standard of care.
As we enter into this new millennium, advances in genetics and biochemistry have enabled greater understanding of how cancer cells behave at molecular levels.
This fuelled the research and development of drugs that target specific parts or mechanisms that cause cancer cells to grow. New agents known broadly as “molecular targeted therapy” began to play a role in cancer treatment.
The results achieved from a combination of chemotherapy and molecular targeted agents in fighting cancer have been greatly encouraging.
For the case of stage IV colorectal cancer, a combination of molecular targeted agents with chemotherapy has been shown in various clinical trials to extend survival by up to 30 months7.
Indeed in just a span of 40 years, research has enabled the survival of stage IV colorectal patients to improve from less than six months to more than two years.
Extension of survival through the use of combination treatment of chemotherapy and molecular targeted agents were also observed in other cancer types, such as cancers of the breasts, lungs and kidneys.
Cancer will continue to be a major health problem in the foreseeable future.
At least now in this age of modern science and technology, we can gather more comfort and confidence that continuous medical research is heading towards the right direction in our quest to improve survival for cancer patients.

Air Sungai Mississippi mula melimpahi tebing
IOWA 19 Jun - Paras air di sungai Mississippi semalam melimpah dari 12 tambak yang dibina di sebalik kejadian banjir buruk yang telah menenggelamkan ladang-ladang mengakibatkan kerugian bernilai berbilion dolar.
Lebih membimbangkan lagi cuaca buruk itu dijangka akan meningkatkan kadar inflasi makanan dunia.
Setakat ini 22 tambak telah pecah dan 10 daripadanya berlaku dalam minggu ini mengakibatkan paras air sungai menyusut dan melimpah ke ladang-ladang berhampiran.
Pihak berkuasa tempatan dan sukarelawan kini sibuk menambak laluan air utama menggunakan beg pasir di kebanyakan kawasan di Amerika Syarikat (AS) bagi menahan tambak daripada pecah dan menyelamatkan ribuan ekar tanaman utama daripada ditenggelami air.
“Kami berasa sedikit lega kerana paras air sungai menurun sedikit tetapi dijangka keadaan ini tidak kekal lama.
“Namun kami masih terus menambak kawasan ini dan keadaan dijangka akan menjadi kritikal malam ini,” kata seorang pekerja dari Agensi Perkhidmatan Kecemasan Daerah Hancock, Kathy Dougherty.
Bencana ini merupakan yang paling buruk melanda Tengah Utara AS dalam tempoh 15 tahun yang turut memusnahkan sebahagian besar kawasan pertanian dan memaksa lebih 10,000 penduduk dipindahkan ke kawasan selamat.
Kerugian akibat bencana ini dijangka mencecah lebih AS$20 bilion (RM64 bilion) dan Iowa merupakan negeri paling teruk terjejas akibat banjir.
Kejadian ini turut mengakibatkan harga di pasaran komoditi, pengeluar makanan dan pengeksport melambung.
Lembaga Perdagangan Chicago melaporkan harga dagangan jagung telah mencatat rekod apabila diniagakan pada harga AS$8.07 untuk satu busyel.
AS menguasai eksport jagung dunia sebanyak 54 peratus, kacang soya 36 peratus dan gandum 23 peratus.- Reuters

Bencana ini merupakan yang paling buruk melanda Tengah Utara AS dalam tempoh 15 tahun yang turut memusnahkan sebahagian besar kawasan pertanian dan memaksa lebih 10,000 penduduk dipindahkan ke kawasan selamat.
Kerugian akibat bencana ini dijangka mencecah lebih AS$20 bilion (RM64 bilion) dan Iowa merupakan negeri paling teruk terjejas akibat banjir.
Kejadian ini turut mengakibatkan harga di pasaran komoditi, pengeluar makanan dan pengeksport melambung.
Lembaga Perdagangan Chicago melaporkan harga dagangan jagung telah mencatat rekod apabila diniagakan pada harga AS$8.07 untuk satu busyel.
AS menguasai eksport jagung dunia sebanyak 54 peratus, kacang soya 36 peratus dan gandum 23 peratus.- Reuters
sultan johor dan batu putih
Pulau itu bukan hak Singapura - Sultan Johor
“Saya akan berikhtiar mencari jalan mendapatkan semula hak kedaulatan Batu Putih yang kini dimiliki Singapura supaya kembali kepada kerajaan Malaysia. Suka saya ingatkan bahawa saya tidak lupa pada Batu Putih. Pulau itu bukan hak Singapura, tetapi hak Johor. Sampai bila pun saya akan cari ikhtiar dapatkan semula pulau milik Johor itu,” titah Sultan Johor, Sultan Iskandar. Titah itu ditegaskan oleh Sultan Iskandar semasa merasmikan pembukaan Persidangan Pertama Dewan Undangan Negeri (DUN) Johor hari Khamis. Pada 23 Mei lalu, Mahkamah Keadilan Antarabangsa (ICJ) di The Hague, Belanda memutuskan hak kedaulatan Batu Putih diberikan kepada Singapura, manakala Batuan Tengah kepada Malaysia sementara Tubir Selatan diberikan kepada negara yang berada di perairannya. Sementara itu, Menteri Besar Johor, Datuk Abdul Ghani Othman ketika diminta mengulas titah Sultan Johor itu berkata, pihaknya akan mengambil kira perkara yang dibangkitkan oleh baginda tetapi enggan mengulas lanjut mengenai perkara itu. - 19/6/2008

melogikkan pemikiran kita
"Untuk kenaikan harga minyak kali ini. Penstrukturan subsidi yg dibayar menggunakan wang pos. Tahukah anda, Pos Malaysia adalah milik ECM-LIBRA, dan ECM-Libra adalah milik Khairi Jamaluddin menantu Pak Lah. Perancang strategik Pak Lah dari tingkat 4. Bayangkan duit yg masuk ke dalam poket Khairy, setiap RM10 yg dibayar sbg subsidi.. 10 sen akan masuk ke poket sebagai komisen wang pos. Maknanya ada 6 juta kenderaan di malaysia dan setiap kenderaan akan dapat subsidi Rm 620, iaitu RM 6.20 komisen kepada Khairi. Untuk setiap kenderaan RM 6.20 X 6 Juta kenderaan = RM 37 200 000 setiap tahun. Itu tidak termasuk bayaran setiap bulan terhadap VESEL dan Nelayan, juga menggunakan wang pos." Bayaran tunai sebanyak RM200 setiap bulan bagi setiap pemilik dan pekerja vesel rakyat Malaysia yang berdaftar dengan Jabatan Perikanan. Bayaran insentif kepada pemilik vesel pada kadar 10 sen sekilogram hasil tangkapan ikan yang didaratkan oleh vesel perikanan berdaftar di pusat pendaratan ikan di dalam negara. "Pembayaran akan diuruskan oleh Lembaga Kemajuan Ikan Malaysia . Kabinet juga telah memutuskan pengusaha bot penumpang sungai akan diberi bayaran tunai sebanyak 10 sen seliter berdasarkan kuota yang diluluskan," kata Abdullah."Figure2 di atas tidak termasuk "Berapa bilion wang kerajaan akan menjadi simpanan tetap di Pos Malaysia dan berapa untung Pos Malaysia memperniagakan wang itu dengan keuntungan yang didepositkan ke tempat lain."-- Berjuang,berjuang, berjuang dan terus berjuang!!!
