Crocodile mucus use to cure disease

Few days ago, I saw a set of photo of Dr Haron Din (Darussyifa'advisory) with a giant crocodile was uploaded in the facebook. The photo shows the crocodile is to be carried using a blue truck and Jawi texts could be seen written on the truck' body. This confirmed that the photo were taken in Brunei ( It is part of Brunei' law for business where name of company must be written in Jawi, besides Roman text). 

Some speculation was made by some people that the crocodile was captured by Dr. Haron Din, which later found to be not true. Upon reading comments from others, I learned that the crocodile was actually "on-loan" from Louis Zoo (private zoo) in Tutong for medical purposes. Some users mentioned that, Dr. Haron actually plans to get several pints of the crocodile' saliva /mucus to cure some (skin) diseases. This theory is supported by a claim that crocodile never get sick even if they feed on dead animals only. 

Besides that, crocodile are always found to live in a dirty swamp or river and full of bacteria. Eventhough the environment are worsen, dirty and labelled as "toilet water" standard, but crocodile still can cure themselves after getting bruises or deep and serious cuts from fighting, accidents or other means . Isn't that amazing? The strong immune system presents inside the crocodile body is undeniably amazing, where human can easily infected and can get killed due to infection by bacteria- crocodile doesn't have to worry about this. Based on this observation,  is claimed that Dr Harun wants to make use of these information and knowledges to help in curing human (skin) diseases

Prophet Muhammad s.a.w. (pbuh) said there is a cure for every disease.

One user also mentioned that, this medical practice is not recently found but have been practiced by people long time ago. However, I cannot guaranteed the originality of those claims by public regarding to reason behind this rehabilitation technique.

# Darussyifa is an Islamic alternatival medical centre present in Brunei. This medical centre mainly use Al-Quran verses / Ruqyah to cure human diseases. 

1) Allah says

" And We send down of the Qur'an that which is healing and mercy for the believers, but it does not increase the wrongdoers except in loss." ( surah Al-Isra' verse 82)
