Two seeds you can buy today may soon need a licence
What happened
On 2 October 2026 the Home Office said it wants to change the rules on who can buy two ordinary-looking seeds. The first is the castor bean. The second is the rosary pea. Both are sold today, often online, and both are used in gardens and crafts. Both also contain a natural poison. Castor beans contain ricin. Rosary peas contain abrin. Under the plan, both seeds would be added to the regulated poisons list in the Poisons Act 1972. That would make it a criminal offence to sell them to a member of the public who does not hold a licence. The Home Office also wants to tighten access to other chemicals that can be used to make explosives, and to make shops report suspicious sales. The proposals are not law yet. They are out for consultation. The consultation opened on 1 October 2026 and closes at 11:59pm on 11 November 2026. Anyone can respond, by online survey, by email or by post to the Home Office CBE Threats Unit in London. The Security Minister, Dan Jarvis, said: "Protecting the public is our first duty. While these substances can have legitimate uses, we must stop them from being weaponised." The change follows the first phase of the Southport Inquiry. The inquiry found that the attacker had bought castor beans online and used them to make ricin.
Why this matters
Most people have never thought about castor beans. That is exactly the point. The seeds are cheap. They are legal. They arrive in a padded envelope like any other parcel. Until now, nothing stopped someone buying a large bag of them with no questions asked. The Poisons Act splits dangerous substances into two groups. 'Reportable' substances can be sold, but sellers must tell the authorities about suspicious orders. 'Regulated' substances are much tighter. A member of the public needs a licence to buy them at all. Moving these two seeds into the regulated group is a real change, not a tidying-up exercise. It would also affect the shops, websites and garden suppliers that sell them. There is a second reason to pay attention. The Home Office is asking the public what it thinks, and the window is short. Six weeks is not long. Once it closes, it closes.
What the evidence actually says
Ricin and abrin are not new discoveries. Both have been studied for decades, and both are recognised worldwide as highly toxic. The Home Office is careful about one point, and it is worth repeating. These substances have real, lawful uses. Castor oil, made from castor beans, is used in medicines, soaps and industry. Researchers and manufacturers need access to the plants and the seeds. So the stated aim is balance. The consultation documents say the goal is to make sure the system 'remains effective, proportionate and responsive to current national security and public safety risks, while maintaining access for legitimate users'. It is also honest to say what the Home Office has not published. There is no figure in the announcement for how many castor beans are sold in the UK each year, or how many suspicious sales have already been reported. The case for change rests mainly on the Southport Inquiry's finding that the existing rules let an attacker buy what he needed. That is a specific, evidenced gap rather than a broad claim about rising risk. Readers should treat it as such.
Practical advice
Nothing changes today. The seeds are not yet on the regulated list, and no new offence is in force. If you grow plants, it is still worth knowing what is in your garden. Castor oil plants are grown for their large, striking leaves. Their seeds are the poisonous part. Rosary pea seeds are small, shiny and red with a black tip, and are sometimes sold in jewellery and craft kits. Keep both well out of reach of children and pets. Seeds that look like beads are exactly the kind of thing a small child picks up. If you think a child has swallowed any plant seed, do not wait to see what happens. Ring 111 for advice, or 999 if the child is drowsy, struggling to breathe or being sick repeatedly. Take the packet or a photo of the plant with you. If you sell seeds, plants or craft kits, read the consultation now rather than in November. If the rules change, your paperwork changes with them. And if you want a say, you have until 11 November 2026.
What to know
The Home Office has proposed adding castor beans and rosary peas to the regulated poisons list under the Poisons Act 1972. If that happens, selling them to an unlicensed member of the public would become a criminal offence. Other explosives precursors would be restricted further, and shops would have to report suspicious sales. The plan follows the Southport Inquiry's finding that the attacker bought castor beans online to make ricin. The consultation runs from 1 October to 11:59pm on 11 November 2026. Nothing has changed yet, but the deadline for comments is firm.
