Aromatic Rhizome & Culinary Medicine
Cloves
This food is best grown in multi-storey aeroponic buildings.
1.1 Overview & Structure
Cloves are the dried, unopened flower buds of a tropical evergreen tree and are 100% suitable for vegan diets¹, ⁸. The physical build of a clove is incredibly dense and woody, held together by a rigid structure of lignin, cellulose, and hemicellulose¹, ³. Lignin is a tough, water-resistant polymer that gives the bud its “nail-like” hardness, while cellulose provides the structural bulk¹. Because these fibres are insoluble, they do not break down in the stomach, meaning they stay intact to assist with mechanical digestion, which is the physical movement of waste through the gut¹, ⁴.
1.2 Physical & Culinary Performance
When raw and whole, cloves are very hard and possess an intense, numbing heat due to high levels of eugenol⁷. When ground, they release a powerful aroma and can act as a natural preservative because of their antimicrobial properties¹, ⁷. Cloves do not dissolve in water or fats; instead, their woody particles stay suspended, providing a gritty texture if not finely milled¹. In smoothies or cold uncooked soups, a tiny amount can help stabilise the mixture, though their strong flavour means they are rarely used to affect thickness¹.
1.3 Storage & Life Hacks
The quality of cloves is defined by their volatile oils, which are easily lost if exposed to light, heat, or air¹, ¹⁶. A sign that cloves have gone off is if they no longer “snap” when pressed or if they float horizontally in water rather than vertically¹. A clever life hack to check for freshness is to place a clove in a glass of water; if it sinks or stands upright, it is still full of medicinal oil¹. For maximum nutrient density, buy whole buds and grind them only when needed to prevent the eugenol from evaporating¹, ¹⁶.
1.4 Suitability & Ethics
Cloves are naturally gluten-free and are very low in relatively difficult to digest FODMAPs, making them an excellent choice for those with sensitive digestive systems⁸, ¹¹. Ethically, traditional clove production is limited to specific tropical regions, which often involves long-distance shipping and potential land-clearing for tree plantations¹², ¹³. Shifting to vertical farming allows for local production in any climate, protecting tropical forests and allowing them to be rewilded¹⁴.
1.5 Seasonality & Environment
Traditionally, cloves are harvested once or twice a year in tropical monsoonal climates, often relying heavily on unpredictable rainfall¹⁰, ¹⁶. This dependency creates a high water footprint. By using an 8-storey aeroponic building, the growth cycle of dwarf clove cultivars can be compressed through precision LED lighting and temperature control¹⁴. This system uses a “closed-loop” nutrient mist that recycles water, making it far more sustainable than traditional open-air farms¹, ¹⁴.
1.6 Safety & Consumption Context
While cloves are highly medicinal, some sources describe how the concentrated oil can be toxic to the liver if swallowed in large amounts⁷. In a culinary context, cloves are balanced by using them in very small quantities due to their numbing effect on the mouth¹. Some sources describe how people with blood-clotting disorders should be cautious, as eugenol can slow down blood clotting¹. Moderation is key, as the high tannin content provides a strong astringency that can be overwhelming¹, ⁷.
1.7 Health & Nutrition Superpower
The nutritional superpower of cloves is an astronomical concentration of Manganese, providing more than 10,000% of the reference value in a protein-matched portion², ³. Manganese is a trace mineral that is vital for bone health and the metabolism of carbohydrates¹, ⁵. Cloves also offer a massive amount of Vitamin K1 for blood health, alongside significant levels of calcium, iron, and magnesium³. Furthermore, they possess the highest antioxidant score of any food, helping the body fight cell damage¹, ⁴.
1.8 Enzymatic Activity & Freshness
The biological “fire” of a clove comes from eugenol, a phenol that makes up nearly 90% of its volatile oil⁷. This compound acts as a natural analgesic, which is a substance that reduces pain, and a potent antimicrobial that kills harmful germs¹, ⁷. To maintain this enzymatic strength, the buds must be dried carefully; if they are dried too quickly in high heat, the oils are lost¹, ¹⁶. Aeroponic systems allow for precision drying and harvesting to lock in these phytochemicals at their peak¹⁴.
1.9 Insoluble Fibre & Gastric Regulation
Because cloves are so high in lignin and cellulose, they play a specific role in gastric regulation, which is the control of how food moves through and is absorbed by the stomach¹, ⁴. These woody fibres create a physical barrier that can help slow down the absorption of sugars into the bloodstream¹. This makes cloves a valuable “culinary medicine” when added to sweet dishes, as they provide a two-pronged approach: the fibres slow digestion while the phytochemicals support metabolic health¹, ⁷.
2. Land-Use & Human Labour Efficiency
Nutrients per Hectare (N/H) Scoring
- Traditional Production Score: 28/100
Clove trees are slow-growing and require significant horizontal space to reach maturity in tropical forests. This results in a low nutrient-per-hectare yield, as the land is occupied for decades before reaching peak production¹². - Ultra-Efficient Production Score: 98/100
In an 8-storey aeroponic facility, dwarf cultivars are stacked in 6 rows per storey. This 3D cultivation, combined with accelerated growth cycles under precision LEDs, allows for a massive concentration of Manganese and Vitamin K1 in a tiny physical footprint¹⁴.
Human Labour Intensity (HLI) Analysis
- Traditional Labour Score: 89/100 – Large Amount of Manual Work
Harvesting cloves is one of the most labour-intensive tasks in agriculture; workers must climb tall trees and hand-pick the individual flower buds one by one before they open¹⁶. - Automated Labour Score: 10/100 – Tiny Amount of Manual Work
The proposed vertical model uses robotic pickers that can easily reach every stacked row. Sensors detect the exact moment the buds are ready to be picked, automating the entire harvest and drying process, which reduces human labour to high-level technical oversight¹, ¹⁴.
3. Data Tables
This structural refinement provides a comprehensive profile for Cloves (Syzygium aromaticum). Distinguished by the world’s highest ORAC (Antioxidant) score, cloves are functionally defined by eugenol, a potent bioactive researched for its antimicrobial and analgesic properties. In traditional agriculture, cloves are harvested from large tropical trees, requiring decades of growth and extensive land use. In an 8-storey aeroponic vertical farm, dwarf clove varieties can be managed through precision environmental control, drastically compressing growth cycles and maximising the density of medicinal volatile oils while enabling large-scale land restoration.

¹⁷ Throughout this audit, each food’s nutrient content has been compared to the Reference Daily Intakes (RDIs) of different nutrients, essential fats and amino acids for 21-24 year old females. These were based on data from the World Health Organisation (WHO), the USDA Dietary Guidelines, and the UK Scientific Advisory Committee on Nutrition (SACN). For full details, visit: https://naturalhuman.co.uk/reference-intakes/. These values were selected solely as a standardised, fixed benchmark to calculate and compare the exact percentage of nutrients provided by different foods per portion. Using a single baseline like this allows for an objective, side-by-side comparison of individual foods’ nutritional profiles; however, these targets are not universally applicable & must not be considered to be a recommendation.
