Gossypium herbaceum L. Mian Zi Soo or Mian Hua Gen (Cotton) (root) Gossypol, hemigossypol, 6,6 -dimethoxylgossypol, aflatoxin (in seed), methoxylhemigosipol, acetovanillone, hirsutrin (in leaf).33 Antitussive, treat bronchitis. 

Strigol has also been reported recently in root cultures of the broad-leaved herbaceous weed Menispermum dauricum54 In this way, the use of LC/MS/MS techniques has revealed a powerful analysis tool for minor compounds. By using this methodology, a new isomer of strigol, the structure yet unknown, has been detected in sorghum root exudates, and the presence of alectrol or orobanchol in cotton root exudates has been discarded.2 These results are summarized on Table 6.2. 

Tree declines leaves yellow, die, but remain on tree. Cause Cotton root rot. Roots of infected trees are brownish, rotted, and soft. Cotton root rot fungus lives in the soil for 5 years or more, thriving especially in areas with heavy, moist, alkaline soil. An acid-type fertilizer might help mildly affected trees, but dig up dying trees and do not replant with pecans. 

Other diseases can be checked by making your soil more acidic. Scab is most destructive in soils with pH higher than 5.7. To avoid scab, do not plant potatoes in soil that has been recently limed, and adjust soil pH, if necessary, to below 5.7. Cotton root rot, which is prevalent in the Southwest and attacks more than 1,700 plant species, favors a soil pH higher than 8.0. One part of the multifaeeted approach needed to control this disease is to acidify the soil.

Asclepias syriaca. Milkweed silkweed wild cotton. Root of Asclepias syriaca L. 04. cornuti Decaisne), Asclepiadaceae. Habit. Canada to North Carolina and Kansas. Constir. Asclepiadin, asclepion—a bitter principle tannin, volatile oil. 

Cotton-root Bark. Dried root-bark of one or more of the cultivated species of Gossypium herbaceum L. and of other species of Gossypium, Malvaceae. Habit. Asia (India. China. Arabia), Egypt, U.S., West Indies, S. America, Australia, Spain, etc. Const. Yellow chromogen about 8% of a pale yellow resin, fixed oil, sugar. 

BASF 13 338 decreased the relative proportion of linolenic acid in the membranes of cotton root tips regardless of the growth temperature. In addition, BASF 13 338 blocked the low temperature-induced increase in linolenic acid in root tips. BASF 13 338 did not affect linolenic acid levels at 30° in hypocotyl tissue from the same cotton plants. The desaturation step only became sensitive to BASF 13 338 at low temperatures. This could indicate either a lower rate of desaturation in hypocotyls, a different control mechanism, or a difference in the desaturation enzymes between the two tissues.

Cotton and Levant cotton root barks have traditionally been used as abortifacients (Conway and Slocumb 1979 Felter and Lloyd 1898 Moore 1978). A number of animal studies have indicated that the compound gossypol has embryo-toxic activity, while other studies have indicated no such activity and a lack of teratogenic effects (Li et al. 1989 Qian and Wang 1984 Randel et al. 1992 Sein 1986 Lin et al. 1985). Based on this information, use during pregnancy is not recommended except under the supervision of a qualified healthcare practitioner. 

No information on the safety of cotton root bark during lactation was identified. While this review did not identify any concerns for use while nursing, safety has not been conclusively established. 

Cotton and Levant cotton root barks have traditionally been used as abortifacients (Conway and Slocumb 1979 Felter and Lloyd 1898 Moore 1978). An Eclectic medical text reported that cotton acts as an emmenagogue and parturient (Felter and Lloyd 1898). 

No information on the safety of cotton root bark during lactation was identified.

Amenorrhea due to pregnancy might be addressed using herbs with abortifacient or uterine stimulant activity (e.g., pennyroyal, artemisia, cotton root bark). Abortifacient activity may involve reduction in maternal progestogen and testosterone levels, as well as an increase in immunoreac-tive cells (Al-Dissi et al. 2001 Boareto et al. 2008 Mukherjee et al. 1996 Talwar et al. 1997).
