Accounting Policies [Abstract]
Nature of Operations [Text Block]	NOTE 1 – NATURE OF OPERATIONS AND MANAGEMENT’S PLANS Since 2014, our team has been committed to researching the application of cannabinoids such as Tetrahydrocannabinol (“THC”) and Cannabidiol (“CBD”) in combination with other compounds to address various ailments, including Alzheimer's disease. With our research, we have developed intellectual property, formulations, and wellness and lifestyle brands. In Fiscal 2021, we were awarded a patent for our cannabinoid-based formulation treatment of seizures in humans and veterinary animals. This followed our Fiscal 2019 and Fiscal 2020 awards of patents for our formulation addressing pain and formulations addressing Cachexia and eating disorders, respectively. Since 2014, the Company has also filed nine other patent applications to address various diseases such as Alzheimer's, pain, stammering, seizures, eating disorders, and fatigue, among others. IGC has two segments: Life Sciences and Infrastructure. The Company’s Life Sciences segment, managed from the United States, involves: a) the development of potential new drugs, subject to applicable regulatory approvals, b) hand sanitizers and several hemp-based CBD products and brands, in various stages of development, for sale online and through stores, c) wholesale of hemp extracts including hemp crude extract and hemp isolate, among others, d) white labeling of hemp-based products and e) the offering of tolling services like extraction and distillation to hemp farmers. Our revenue in Fiscal 2021 was primarily derived from this business segment. The Company’s Infrastructure segment, managed from India, involves: (a) the execution of construction contracts, (b) the rental of heavy construction equipment, and (c) the purchase and resale of physical commodities used in infrastructure. Our revenue in Fiscal 2020 was primarily derived from this business. Information about our infrastructure products and service offerings is available at www.igcinc.us. In the Pharmaceutical channel, we created a patent-pending formulation based on ultra-low dosing of THC in combination with other compounds that, in Fiscal 2021, under an INDA filed with the FDA, underwent the first phase of a phase 1 trial on safety and tolerability. The phase 1 trial is ongoing at the time of this filing. We are motivated by the potential that, with future successful results after appropriate further trials, IGC-AD1 could contribute to symptom relief for some of the 50 million people around the world that are expected to be impacted by Alzheimer's disease by 2030 (WHO, 2020). Data from pre-clinical studies, including cell lines and animal models, showed the formulation, IGC-AD1, inhibited the accumulation of the neurotoxic protein beta-amyloid (“Aβ”) that leads to the buildup of plaques, as well as the hyperphosphorylation of tau that leads to Neuro Fibrillary Tangles (“NFT”) two of the hallmarks of Alzheimer's disease. In pre-clinical studies, certain combinations of IGC-AD1 also showed memory improvement and neurogenesis. For the Retail Channel, in Fiscal 2021, we developed wellness and lifestyle brands, Holief™, Herbo™, and Sunday Seltzer™. We plan on marketing these brands, including to the U.S. based Latino market, which is among the fastest-growing segment in the U.S. GDP that in 2018 was around $2.6 Trillion. (Forbes, 2020). It is projected that the Hispanic population will reach 111.22 million by 2060 from 59 million in 2018 (Statista, 2021). The Company’s principal office is located in the U.S. in Maryland. Additionally, the Company has a facility in Washington and offices in Colombia, Hong Kong, and India. As of March 31, 2021, the Company had the following direct operating subsidiaries: Techni Bharathi Private Limited (TBL), IGCare LLC, Holi Hemp LLC, IGC Pharma LLC, SAN Holdings LLC, Sunday Seltzer, LLC and Colombia-based beneficially-owned subsidiary Hamsa Biochem SAS (Hamsa). The Company’s fiscal year is the 52- or 53-week period that ends on March 31. The Company is a Maryland corporation established in 2005. The Company’s filings are available on www.sec.gov.
