Nature Life International
Jacob Vadakkanchery founded Nature Life International in 1998. They now have several nature cure hospitals across Kerala. Patients are advised naturopathic lifestyle and diet, chemical free foods, and natural methods of treatment at these centers. They also sell several products via these centers and via their website.

Jacob Vadakkanchery resigned as chairman of Nature Life International in May 2018 after cases were registered against him for allegedly spreading lies regarding Nipah virus.

In January 2018 Nature Life Hospital in Kochi was asked to pay a fine of Rs. 4 Lakhs  by the Consumer Disputes Redressal Forum for gross negligence for death of a lawyer Vinayanandan that happened in this center in 2005. The forum president Rose Jose in her order said that though the direct cause of the death was not because of the treatment at hospital there was gross negligence in giving care and attention to the patient. The forum took into consideration the submission of the hospital and Vadakkanchery that the relatives had not shown the ECG report of Vinayanandan at the time of admission indicating that the deceased was a heart patient.

Activism
Vadakkanchery has in the past run several campaigns against liquor shops and chemical based farming.

He also regularly campaigns against preventive medicines and vaccines which has resulted in many cases being filed and getting him arrested several times During the public health crisis of Nipah virus infection in Kerala, he claimed that Nipah virus does not exist, and that the disease is a creation of the "medical mafia". He said that fruit bats, the primary reservoir of Nipah virus, eat only fruits and therefore cannot harbour viruses. He asked people to refrain from eating previously cooked meat to avoid spreading of fever instead of going to the hospital. He also challenged the public to visit the Nipah affected area of Perambra. He expressed confidence that no naturopath has yet been killed by Nipah.

According to Vadakkanchery, vaccination is a part of the 'medical propaganda'. He claims that vaccines have been made from aborted fetus and therefore should not be administered to children. His public talks have been alleged to be a reason for reduced vaccination rates, which eventually caused the diphtheria outbreak in Malappuram district of Kerala.

Vadakkanchery has campaigned against the state government program for prevention of leptospirosis during the public health crisis after 2018 floods in Kerala. He alleged that doxycycline, the medicine used for prevention and treatment of leptospirosis would cause fatal allergic reaction. He proclaimed that pharma companies were using leptospirosis scare to increase the sale of their medicines, and therefore, one should resort to naturopathic ways of treatment.  He was then arrested by police for spreading misinformation against public health campaigns, following a written complaint from the health minister.
